OPINION
Following a jury trial, Appellant Lenwood Mason was found guilty of first-degree murder for the lolling of Iona Jeffries. The jury returned a verdict of death, and on February 20, 1996, the trial court formally imposed the death sentence. Upon petition by Appellant’s trial counsel, the court ordered that counsel be permitted to withdraw, as private counsel had been retained. New counsel for Appellant filed a petition for collateral review under the Capital Unitary Review Act, 42 Pa.C.S. § 9570, et seq., 1 which the trial court denied. This direct appeal followed. 2 For the reasons presented below, we affirm the judgment of sentence.
Although Appellant concedes that he fatally stabbed Iona Jeffries, he claims in his first allegation of error that there was insufficient evidence to support the jury’s verdict of first-degree murder. As in all cases in which the death penalty has been imposed, this Court is required to independently review the record to determine whether the evidence is sufficient to sustain the verdict for murder in the first degree.

See Commonwealth v. Zettlemoyer,
Evidence is sufficient to sustain a conviction for first-degree murder where the Commonwealth establishes that the defendant acted with a specific intent to kill, that a human being was unlawfully killed, that the defendant did the killing and that the killing was willful, deliberate and premeditated. 18 Pa.C.S. § 2502(d);
Commonwealth v. Spotz,
Viewed under these standards, the record below establishes that on March 31, 1994, police were called to the 3800 block of Clearfield Street in Philadelphia. Officer Terry Brown observed Appellant walking on Clearfield Street, with Iona Jeffries close to his side. Noting a frightened look on Ms. Jeffries’ face, the officer approached her and asked if she was all right. The officer noticed bruises on Ms. Jeffries’ forehead, shoulder, neck and mouth. Although Appellant told the officer that Ms. Jeffries had been attacked by several other women, Ms. Jeffries informed the officer that Appellant had actually caused her injuries. Ms. Jeffries explained to the officer that she was reluctant to press charges against Appellant, as she feared he would kill her. Based on his own observations and Ms. Jeffries’ statements, however, the officer placed Appellant under arrest.
Approximately three months later, on the evening of June 18, 1994, Ms. Jeffries was at a bar, Cadillac Slim’s, with Appellant and several of her friends. Appellant had been released from prison two days earlier, on June 16, 1994. *508 When Ms. Jeffries and her friends decided to leave Cadillac Slim’s and go to another club, Ms. Jeffries asked that a male acquaintance drive Appellant home, as she did not want him to accompany her to the club. Upset by Ms. Jeffries’ plans to exclude him, Appellant yelled, “You want it like that?” and ran out of the bar.
At approximately 9:30 the following morning, Ms. Jeffries’ mother, Mrs. Wisteria Jeffries, was at her home when she heard Appellant banging on the door. As Wisteria Jeffries approached the door, she saw Appellant’s hand protruding through the screen door. When Wisteria Jeffries asked Appellant what he wanted, he replied that he needed to speak with Ms. Jeffries. Wisteria Jeffries explained that Ms. Jeffries was asleep. After Appellant insisted that he speak with Ms. Jeffries, Wisteria Jeffries told Appellant to wait outside while she got Ms. Jeffries. She locked the door and went upstairs to Ms. Jeffries’ room, where Ms. Jeffries was sleeping on a bed with her then three year-old son, Anthony. Ms. Jeffries refused to come downstairs. Wisteria Jeffries returned to the front door and told Appellant that Ms. Jeffries was sleeping and that he would have to wait to speak with her. Appellant then forced his way into the house, pushed past Wisteria Jeffries, and ran up the stairs. Wisteria Jeffries immediately called the police.
Wisteria Jeffries retrieved a knife from the kitchen and began to head upstairs, when she saw Appellant descending the steps. Appellant stated to Wisteria Jeffries, “I got her now.” At that point, Wisteria Jeffries attempted to stab Appellant, but he pushed her aside and ran outside, where a neighbor, Greg Bell, saw Appellant placing what appeared to be a knife into the waistband of his pants. Wisteria Jeffries ran upstairs to Ms. Jeffries’ bedroom and found Ms. Jeffries bleeding profusely from multiple stab wounds. Police and rescue units arrived and Ms. Jeffries was taken to the hospital, where she was pronounced dead. Later that same day, Appellant surrendered to the police and was charged with murder in the first degree, burglary and possessing an instrument of crime.
*509 At Appellant’s trial, Dr. Haresh G. Mirchandani, the chief medical examiner for Philadelphia County, testified that the cause of Ms. Jeffries’ death had been multiple (eighteen) knife wounds to the body. According to Dr. Mirchandani, Ms. Jeffries had suffered knife wounds to her head, neck, chest, back, abdomen, arm, groin and leg. Ms. Jeffries’ son, who was four years old at the time of the trial, testified that he was on the bed with his mother when Appellant entered the bedroom and stabbed his mother with a knife.
Appellant testified on his own behalf, claiming that he had been drinking and doing drugs, including PCP for the first time, at the bar on the night before the murder. He testified that after he smoked the PCP, everything went blurry and that he did not recall leaving Cadillac Slim’s or going to Ms. Jeffries’ house on the morning of her murder. He further maintained that he did not regain his senses again until late in the evening on the day of the murder, when he was already in jail. Appellant’s mother and brother also testified in Appellant’s defense. Essentially, they claimed that when they saw Appellant on the day of the murder, he was under the influence of drugs and that his condition was unlike any “high” that they had ever seen him experience.
On February 15, 1996, the jury found Appellant guilty of first-degree murder, burglary and possessing an instrument of crime. After a penalty hearing, the jury found that there were two aggravating circumstances and no mitigating circumstances. 3 The jury therefore returned a verdict of death for the murder conviction, which the trial court formally imposed on February 20, 1996.
Appellant first argues that there was insufficient evidence to establish that he acted with premeditation, a finding necessary to sustain his conviction for first-degree murder. He essentially contends that the following circumstances sur *510 rounding the crime suggest a lack of premeditation on his part: (1) that he did not threaten Ms. Jeffries or her mother prior to the stabbing, (2) that he did not initially break down the Jeffries’ screen door and (3) that he did not conceal his identity or eliminate the witnesses to the stabbing. This claim fails.
The period of premeditation necessary for first-degree murder “may be very brief.”
Commonwealth v. Green,
Appellant also contends that the jury erred in failing to find that he was acting under the “heat of passion” when he fatally stabbed Ms. Jeffries. This claim lacks merit.
A “heat of passion” defense is a partial defense to murder.
Commonwealth v. McCusker,
Here, Appellant does not claim that his quarrel in the bar with Ms. Jeffries, which occurred more than seven and one-half hours before the stabbing, caused him to kill Ms. Jeffries in the heat of passion. Rather, Appellant claims that he was so intoxicated at the time of the stabbing that he can’t remember whether words were exchanged which would give rise to a heat of passion defense. However, there was no evidence to support a finding that Ms. Jeffries did anything immediately before the stabbing to provoke Appellant so as to cause him to act in the heat of passion. In fact, Ms. Jeffries’ son testified that his mother was just lying on the bed when Appellant came into the room and began stabbing her. N.T., 2/12/96, at 77-80;
see also
N.T., 2/9/96, at 146-47. Thus, the record in the instant case simply does not support Appellant’s speculative claim that he was acting under the heat of passion when he stabbed Ms. Jeffries to death. See
Commonwealth v. Speight,
In his final challenge relating to the sufficiency of the evidence, Appellant maintains that the jury erred in finding a specific intent to kill because he presented evidence to show that he was intoxicated at the time of the killing.
4
By
*512
their verdict, however, the jury clearly disbelieved the evidence that Appellant introduced in an attempt to establish that his intoxication on the day of the stabbing prevented him from forming the specific intent required to support a conviction for firsi>degree murder. It is well settled that such credibility determinations are for the jury to resolve.
See Commonwealth v. Brown, 538
Pa. 410, 437-38,
Thus, we find that Appellant’s arguments challenging the sufficiency of the evidence are meritless. Instead, after an independent review of the record, we agree with the trial court that the Commonwealth presented sufficient evidence for the jury to find, beyond a reasonable doubt, that Appellant committed murder in the first degree when he repeatedly stabbed Ms. Jeffries to death.
See Commonwealth v. Thomas, 552
Pa. 621, 632-34,
For the same reasons advanced in his sufficiency claim, Appellant also argues that the verdict of first-degree murder was against the weight of the evidence. This claim also lacks merit.
A defendant’s request for a new trial based on the argument that the verdict was against the weight of the evidence will only be granted when the verdict is so contrary to the evidence as to shock one’s sense of justice.
Commonwealth v. Spotz,
Here, Appellant has failed to show that the trial court abused its discretion in determining that the verdict was not against the weight of the evidence. Given the facts in evidence in this case, this is not a verdict which shocks one’s sense of justice. Accordingly, we reject Appellant’s contention that the jury’s verdict was against the weight of the evidence.
The next several claims of error raised by Appellant involve the alleged ineffectiveness of his trial counsel. To prevail on such a claim, Appellant must demonstrate that (1) the underlying claim is of arguable merit; (2) counsel’s course of conduct was without a reasonable basis designed to effectuate his interest; and (3) that he was prejudiced by counsel’s ineffectiveness, i.e. if not for counsel’s ineffectiveness, there is a reasonable probability that the outcome of the trial would have been different.
Commonwealth v. Douglas,
Appellant first maintains that counsel was ineffective because he failed to adequately consult with him prior to trial, allegedly meeting with him on only two or three occasions prior to the guilt phase of his trial. This claim fails.
*514
In the first instance, it is well settled that, by itself, the amount of time an attorney spends consulting with his client before trial is not a legitimate basis for inferring the total extent of counsel’s pre-trial preparation, much less the adequacy of counsel’s preparation.
Commonwealth v. Bundy,
*515 Appellant next alleges that counsel was ineffective for failing to conduct an adequate pre-trial investigation. 7 He contends that if counsel would have investigated further, he would have uncovered physical evidence that he and Ms. Jeffries had reconciled and spent time together in the days immediately before the murder. This claim is meritless.
In the first instance, the jury was aware that Ms. Jeffries and Appellant had apparently reconciled before the murder.
*516
Appellant himself testified that he and Ms. Jeffries had spent time together in the days before the murder, had ran errands together on the day before the murder and had gone to Cadillac Slim’s together. Both Appellant’s brother and mother indicated the same during their testimony. Even Ms. Jeffries’ mother, as a witness for the Commonwealth, testified that Ms. Jeffries and Appellant had spent time together in the days before the murder and that Ms. Jeffries had gotten Appellant’s name tattooed on her arm during this time. Likewise, Samantha Edens, Ms. Jeffries’ friend and a witness for the Commonwealth, testified that Ms. Jeffries wanted Appellant to accompany her to Cadillac Slim’s on the evening before the murder and that the two had spent time together before arriving at Cadillac Slim’s. Thus, any evidence allegedly showing the reconciliatory nature of the relationship that Appellant contends should have been unearthed during pretrial investigation would have been merely cumulative of the testimony provided by both defense and Commonwealth witnesses.
See Commonwealth v. Hall,
Appellant contends, however, that physical evidence of his and Ms. Jeffries’ reconciliation in the days preceding the murder, including prison records showing Ms. Jeffries’ visits to him and a motel receipt from the motel room he and Ms. Jeffries shared after he was released from prison, existed. He argues that such physical evidence, if located and introduced by counsel, would have corroborated the testimony regarding the reconciliation. 8 In making this argument, Appellant fails to recognize that even if the jury believed the evidence that Ms. Jeffries and Appellant had rekindled their relationship in the days before the murder, this would in no way have precluded the first-degree murder conviction. The jury could have reasonably concluded that Appellant, despite *517 being on good terms with Ms. Jeffries in the days before the murder, later became angry, decided to kill Ms. Jeffries, and carried out the plan. Thus, this claim of ineffectiveness also fails to offer Appellant any basis for relief.
In a related claim, Appellant argues that he is entitled to a new trial on the basis of after-discovered evidence, which consists of letters written by Ms. Jeffries to him while he was in prison and a picture of Ms. Jeffries visiting him in prison. Appellant asserts, without explanation or elaboration, that because the letters demonstrate the couple’s close and intimate relationship, Appellant’s “acts could only have been the product of ‘heat or passion’ or intoxication.” Appellant’s Brief at 15. This claim is without merit.
After-discovered evidence can only be the basis for a new trial when it: (1) has been discovered after the trial and could not have been obtained at or prior to the conclusion of the trial by the exercise of reasonable diligence; (2) is not merely corroborative or cumulative; (3) will not be used solely to impeach the credibility of a witness; and (4) is of such a nature and character that a different verdict will likely result if a new trial is granted.
Commonwealth v. Wilson,
Here, Appellant fails to satisfy even the first prong of this test. The alleged after-discovered evidence consists of a picture and letters sent by Ms. Jeffries to Appellant while he was incarcerated. There is nothing to suggest that these items were not in the possession of, or accessible to, Appellant at the time of trial. Indeed, Appellant concedes that these items were in a cabinet in Appellant’s home.

In his final claim, Appellant alleges that his trial counsel was ineffective for referring to the stabbing as a “heinous crime” during his guilt-phase closing argument and baldly asserts that this remark supported “the Commonwealth’s efforts to obtain a first-degree murder conviction and death penalty” and “served to fix an unfavorable bias against [Appellant] in the minds of the jury.” Appellant’s Brief at 15. 9 This claim fails.
Appellant specifically challenges trial counsel’s reference to the crime as “heinous” and the making of the following comment during his closing argument to the jury: “You have a very difficult task because you have to sort through the evidence of a rather'heinous crime without emotion, without bias, without sympathy____” N.T., 2/14/96, at 62. However, Appellant fails to assert, much less demonstrate, that counsel
*519
lacked a reasonable basis for the challenged comment or that the use of the comment prejudiced him.
See Commonwealth v. Carpenter,
Given Appellant’s admission that he stabbed Ms. Jeffries and the other evidence of Appellant’s guilt, it is clear that Appellant’s counsel was left with few strategic options for defending his client against a first-degree murder charge. However, the record reflects that counsel’s challenged comment was merely a reminder to the jury that it was the evidence, and not its emotions, that should control the outcome of the case. Head in context, the comment was clearly part of counsel’s strategy to persuade the jury that despite the crime’s gruesomeness, and despite the fact that Appellant had in fact stabbed Ms. Jeffries to death, the evidence showed that Appellant had done so only while he was too intoxicated to form the specific intent necessary for a first-degree murder conviction. Under the circumstances of this case, we fail to discern how this strategy was unreasonable.
See Commonwealth v. Marshall,
Having concluded that Appellant’s conviction for first-degree murder was proper, we are statutorily required to perform an automatic review of his sentence of death. Pursuant to this review, we must affirm the sentence of death unless we determine that:
(i) the sentence of death was the product of passion, prejudice or any other arbitrary factor;
(ii) the evidence fails to support the finding of at least one aggravating circumstance specified in subsection (d); or
(iii) the sentence of death is excessive or disproportionate to the penalty imposed in similar cases, considering both the circumstances of the crime and the character and record of the defendant.
42 Pa.C.S. § 9711(h)(3).
Upon review of the record, we conclude that the sentence of death was not the product of passion, prejudice or any other arbitrary factor, but rather, was based upon evidence properly admitted at trial. We also conclude that the evidence was sufficient to support the finding of at least one aggravating factor, that Appellant had a significant history of felony convictions involving the use or threat of violence to another person. See 42 Pa.C.S. § 9711(d)(9). Appellant’s two previous convictions for robbery were placed before the jury during the penalty phase.
In terms of our duty to determine whether Appellant’s sentence is excessive or disproportionate, we have independently reviewed Appellant’s sentence in light of the sentencing data compiled and monitored by the Administrative Office of the Pennsylvania Courts. We find that the sentence of death imposed upon Appellant is not excessive or disproportionate to the penalty imposed in similar cases. 10
*521 Accordingly, we affirm the verdict and sentence of death. 11
Notes
. The Capital Unitary Review Act was later suspended by this Court.
See In re Suspension of the Capital Unitary Review Act,
. Pursuant to 42 Pa.C.S. § 9711(h), this Court has automatic jurisdiction to review the trial court’s judgment of a sentence of death.
. Specifically, the jury found as aggravating circumstances that Appellant committed the murder of Iona while he was engaged in the commission of a felony, 42 Pa.C.S. § 9711(d)(6), and that he had a significant history of committing crimes of violence, 42 Pa.C.S. § 9711(d)(9).
. A showing of voluntary intoxication can negate the intent necessary for a conviction of first-degree murder and reduce the crime of murder
*512
from first to third degree.
Commonwealth v. Marshall,
. We also note that Ms. Jeffries' mother testified that Appellant did not appear in any way to be under the influence of anything when she talked to him before he broke into her home and stabbed Ms. Jeffries. N.T., 2/9/96, at 158-59. Further, the detective who processed Appellant when Appellant turned himself in also testified that Appellant did not appear to be incoherent in any way but rather "understood completely everything I asked him, he answered very clearly, and he seemed like he knew exactly what he was doing.” N.T., 2/14/96, at 24.
. Appellant alleges that his counsel’s infrequent pre-trial consultations with him resulted in counsel being generally unprepared for the guilt phase of his trial. In support of his argument, Appellant cites to a portion of the record where defense counsel, after the start of trial but before the defense began presenting its evidence, stated that he had not yet had the opportunity to interview two potential defense witnesses. We agree with the Commonwealth, however, that the mere fact that counsel did not succeed in interviewing two potential defense witnesses
*515
until after trial began but before the defense presented its case does not establish ineffectiveness on the part of counsel.
See Commonwealth v. Anderson,
. We note that Appellant’s claims challenging the effectiveness of his trial counsel's pre-trial preparation are raised in light of the following exchange between Appellant and the trial court:
THE COURT: Mr. Mason, your counsel has indicated that he is about to rest your case in chief, specifically that there will be no further evidence forthcoming from the defense. Have you discussed this with your counsel?
APPELLANT: Yes.
THE COURT: And it is likewise your decision that there need not be presented any further evidence on the part of the defense? APPELLANT: Yes.
THE COURT: Are you satisfied with the representation of your counsel up to this point in time?
APPELLANT: Yes.
THE COURT: Are there any witnesses that you wish to present that have not yet been presented?
APPELLANT: No.
THE COURT: Is there any outstanding investigation that you believe needs to be done before your counsel rests his case?
APPELLANT: No.
N.T., 2/14/96, at 10-11.
. Appellant claims that the Commonwealth presented evidence that Appellant stalked Ms. Jeffries and that without physical evidence to contradict the Commonwealth’s theory, the jury only had one take on the nature of Appellant’s and Ms. Jeffries’ relationship to consider. These contentions are simply not supported by the record.
. Appellant fails to adequately develop his argument on this issue and cites to absolutely no case law or other legal support for his bald assertion. An issue will be deemed to be waived when an appellant fails to properly explain or develop it in his brief.
See Commonwealth v. LaCava,
. We note that on June 25, 1997, the Governor signed legislation that removes a proportionality review requirement from the death penalty
*521
statute. Act of June 25, 1997, No. 28 § 1 (Act 28). However, Act 28 is not applicable to the instant case as Appellant's death sentence was imposed prior to June 25, 1997.
See Commonwealth v. Gribble,
. The Prothonotary of the Supreme Court is directed to transmit the complete record of this case to the Governor of Pennsylvania. 42 Pa.C.S. § 971 l(i).
