¶ 1 Appellant, Andrew E. Lillioek, appeals from the judgment of sentence entered on December 4, 1997. After a careful review of the record and relevant case law, we find appellant’s contentions to be meritless and thus affirm.
¶ 2 The relevant facts underlying this case are as follows. On March 4, 1995, a fire erupted at the mobile home of Sandra Lillioek. On June 26, 1996, Sandra Lilliock’s estranged husband, Andrew Lil-lioek, was arrested and charged with arson, risking a catastrophe, recklessly endangering another person, burglary, and criminal trespass. During the jury trial, the Commonwealth presented the testimony of an eyewitness, Judy Dutchko. Ms. Dutchko testified that, on March 4, 1995, she observed a white male, approximately thirty years old and with no noticeable facial hair, driving a white Volks-wagon Rabbit or Plymouth Horizon arrive at Sandra Lilliock’s mobile home. The person entered the mobile home, remained there for a few minutes, and then *241 departed. Several minutes later, Ms. Dutchko noticed flames inside of the home. The Commonwealth also adduced evidence that Sandra Lilliock had recently-separated from appellant and that there was a history of physical abuse by appellant towards his wife. Additionally, the Commonwealth presented the testimony of Jay Whitfield, a former friend of appellant, who testified that he was with appellant at a bar on the night of the fire. According to Mr. Whitfield, appellant left the bar after he learned that his wife was with another man. Later that night, appellant admitted to Mr. Whitfield that he set his wife’s mobile home on fire and that he made it look like a furnace fire by placing rags around the furnace.
¶3 After deliberating upon the evidence presented, the jury returned a verdict of guilty on all counts. Appellant was sentenced to eighteen to thirty-six months’ incarceration. Appellant filed a post-sentence motion, which was denied by the lower court. This timely appeal followed.
¶4 Appellant presents ten questions for our review:
I. Were the verdicts against the weight of the evidence?
II. Did the trial court err in permitting the jurors to take a magnifying glass into [the] courtroom to examine photographs?
III. Did the trial court err in not permitting introduction of all of Sandra Lilliock’s bank records?
IV. Did the trial court err in not instructing the jury with the “false in one, false in all” standard jury instruction?
V. Should the defendant’s sentence be modified?
VI. Was trial counsel ineffective for failing not to object to the admission of “prior bad acts”?
VII. Was trial counsel ineffective for not calling alibi witnesses?
VIII. Was trial counsel ineffective for failing to raise post trial motions on the trial court’s hearsay determination of the police report?
IX. Was trial counsel ineffective for failing to raise post trial motions on the trial court’s limitation of defense witness testimony?
X. Was trial counsel ineffective for failing to raise post trial motions on the inflammatory closing remarks of the district attorney?
Appellant’s brief, at 6 (suggested answers omitted).
WEIGHT OF THE EVIDENCE
¶ 5 Appellant first argues that the verdict was against the weight of the evidence for four reasons: (1) the Commonwealth did not present evidence that established that there was any forcible or unprivileged entry into Mrs. Lilliock’s home in order to sustain the burglary conviction; (2) Ms. Dutchko’s testimony was insufficient to identify appellant as the perpetrator; (3) the two expert witnesses provided conflicting testimony regarding the origin of the fire; (4) the testimony of Mr. Whitfield was inconsistent with other evidence presented by the Commonwealth; and (5) a portion of Mrs. Lilliock’s testimony was refuted at trial.
¶ 6 The decision to grant a new trial based on a challenge to the weight of the evidence is within the sound discretion of the trial court. Absent an abuse of discretion, we will not reverse the trial court’s ruling.
Commonwealth v. Eddowes,
¶ 7 We find that appellant’s first argument is meritless. Forcible entry is not an element of the crime of burglary. In order to be convicted of burglary, the Commonwealth must establish that the defendant “enterfed] a building or occupied structure, or separately secured or occupied portion thereof, with intent to commit a crime therein, unless the premises are at the time open to the public or the actor is licensed or privileged to enter.” 18 Pa. C.S.A. § 3502. The Commonwealth presented evidence to satisfy all elements of the crime of burglary. The Commonwealth need not have presented evidence of forcible entry.
¶ 8 As to appellant’s second claim, we find that Ms. Dutchko’s description of the assailant was sufficient. Ms. Dutchko testified that she witnessed a white Volks-wagon Rabbit or Horizon pull up to the mobile home on the night of the fire. She observed a white male, approximately six feet tall, with short hair and no apparent facial hair, exit the car and walk towards the front door. A light went on in the mobile home and then minutes later, the light went off. The man exited the mobile home and attempted to hide from Ms. Dutchko’s view. Soon after he left the premises, Ms. Dutchko saw that the mobile home was on fire. Appellant is a white man, is five feet, eleven inches tall, has brown hair, and owned a white ■ Volks-wagon Rabbit at the time of the fire. When we consider Ms. Dutchko’s testimony, together with other evidence presented by the Commonwealth, we find that the evidence was sufficient to identify appellant as the assailant.
¶ 9 Appellant next challenges the weight of the evidence on the ground that the two expert witnesses presented by the Commonwealth provided contradictory testimony as to the origin and cause of the fire. Trooper Brian Craig examined the mobile home shortly after the fire was extinguished. Agent William J. Petraitis of the Bureau of Alcohol, Tobacco and Firearms, however, based his opinion upon his review of Trooper Craig’s report, witness statements, and photographs of the scene. While appellant is correct in stating that the experts provided differing opinions as to the origin and cause of the fire, both experts did conclude that the fire was a result of arson. The experts’ testimony, particularly concerning their opinion as to the fire being a result of arson, support the conviction, especially when considered together with the other evidence presented at trial. In any event, where evidence is conflicting, the issue of credibility of witnesses and a resolution of the conflict is a matter solely of the trier of fact.
Commonwealth v. Russell,
¶ 10 Appellant also challenges the weight of the evidence on the ground that the testimony of Jay Whitfield was contradictory and inconsistent with other evidence presented by the Commonwealth. Mr. Whitfield testified as to the statements made to him by appellant about how appellant started the fire. His testimony as to appellant’s statements admitting how he started the fire differed from the experts’ analysis of the origin and cause of the fire. Nevertheless, this does not render the verdict against the weight of the evidence because both the experts’ and Mr. Whitfield’s testimony support a finding that appellant started the fire. We reiterate that any inconsistencies in the evidence are a matter for the trier of fact to resolve, and we will not disturb the verdict on that basis. Russell, supra.
¶ 11 Finally, appellant argues that Mrs. Lilliock’s testimony regarding appellant’s motive was refuted at trial. Mrs. Lilliock testified that appellant stated that he needed a tragedy to reunite his family. This statement had been made in the context of a discussion about the terminal illness of a family friend. Ms. Lilliock testified that appellant’s statement was made after the friend’s death. On cross-
*243
examination, however, the defense presented evidence establishing that the friend did not die until after the fire occurred. Appellant now asks us to disturb the verdict because of this minor inaccuracy. “As the phenomenon of lying is within the ordinary capacity of jurors to assess, the question of a witness’s credibility is reserved exclusively for the jury.”
Commonwealth v. Davis,
JUROR USE OF A MAGNIFYING GLASS
¶ 12 Appellant argues that the trial court erroneously permitted the jurors to take a magnifying glass into the courtroom to examine photographs that were admitted into evidence. At trial, both parties used a visual presenter, a video machine that enlarges a regular photograph on a video monitor, to assist them in presenting photographic evidence to the jury. A video presenter is not available to the jury in the jury room. As a result, the jury requested a magnifying glass in order to view the photographic evidence. According to appellant, the juror’s use of the magnifying lens violated Pa.R.Crim.P. 1114, which states:
1. Upon retiring, the jury may take with it such exhibits as the trial judge deems proper, except as provided in paragraph 2.
2. During deliberations, the jury shall not be permitted to have a transcript of any trial testimony, nor a copy of any written or otherwise recorded confession by the defendant, nor a copy of the information.
Pa.R.Crim.P. 1114. “In interpreting this rule, [our Supreme Court] ... has noted that such trial court decisions are committed to the trial court’s discretion and will not be reversed absent an abuse of that discretion.”
Commonwealth v. Rued,
¶ 13 We recognize the difficult task of the jury in determining the facts. “[Wjhere materials inform a jury and aid it in the difficult task of determining facts, the jury should be permitted to study those materials during its deliberations.”
Commonwealth v. Bango,
EXCLUSION OF EVIDENCE OF BANK RECORDS
¶ 14 In order to establish ownership of the mobile home by Mrs. Lillioek and her right to deny access to the mobile home to appellant, Mrs. Lillioek testified that she made down-payments on the trailer and made a final payment of $1,300 at the time of closing. She later placed a stop payment order on the closing check because of misrepresentations regarding the date of manufacture made by the seller. The defense presented the testimony of Denise Poole of the Irwin Bank and Trust Company, who testified as to the status of Mrs. Lilliock’s checking account at the time of the fire. According to Ms. Poole, Mrs. Lilliock’s account upon which the closing check was drawn contained only $358.41 at the time that she issued the check. Appellant sought to show the status of Mrs. Lilliock’s account prior to the time this check was issued. The court, however, did not allow the admission of such evidence and limited Ms. Poole’s testimony to Mrs. Lilliock’s account balance on the date of the closing check. Appellant now challenges the trial court’s ruling.
*244
¶ 15 Admission of evidence is within the sound discretion of the trial court and will be reversed only upon a showing that the trial court clearly abused its discretion.
Commonwealth v. Bardo,
¶ 16 The trial court concluded that the bank records were irrelevant to the issues at hand and thereby held that they were inadmissible. Appellant claims that the evidence should have been admitted to prove that Mrs. Lillioek did not have the financial security to purchase the mobile home at the time that it was destroyed. Appellant has not explained how Mrs. Lil-liock’s financial instability is relevant to the issues in the case. We agree with the trial court’s finding that the evidence was inadmissible as irrelevant.
“FALSE IN ONE, FALSE IN ALL” STANDARD JURY INSTRUCTION
¶ 17 Appellant requested that the trial court instruct the jury with the maxim “falsus in uno, falsus in omnibus” (“false in one, false in all”) because he believed that the Commonwealth’s witnesses provided numerous inconsistent and untrue statements. The “false in one, false in all” instruction states that “if a witness willfully and corruptly swears falsely to any material fact in a case, the jury are at liberty to disregard the whole of his testimony.”
Commonwealth v. Parente,
MODIFICATION OF SENTENCE
¶ 18 Appellant challenges the sentence on two grounds: (1) the evidence fails to support the verdicts and thereby fails to support the imposition of the consecutive sentences imposed; and (2) the consecutive sentences constitute a failure of the court to consider the mitigating evidence offered by appellant. Appellant’s brief, at 17. Appellant has not developed these arguments in any fashion and has merely made bald assertions. Issues as to which defendant developed no argument and cited no authority are waived.
Commonwealth v. Luktisch,
INEFFECTIVENESS OF COUNSEL
¶ 19 Finally, appellant challenges the effectiveness of counsel on five grounds: (1) counsel failed to object to the admission of prior bad acts; (2) counsel failed to call alibi witnesses; (3) counsel failed to raise post trial motions on the trial court’s hearsay determination; (4) counsel failed to raise post trial motions on the trial court’s limitation of defense witness testimony; (5) counsel failed to raise post-trial motions on the inflammatory closing remarks of the district attorney.
¶20 The standard of review for claims of ineffective assistance of counsel is well • settled. In order to prevail, appellant must demonstrate that the underlying claim is of arguable merit, that
*245
counsel’s actions had no reasonable basis designed to effectuate appellant’s interests, and that counsel’s actions prejudiced appellant.
See, e.g., Commonwealth v. Correa,
Failure to Object to Admission of Pri- or Bad Acts
¶ 21 At trial, the trial court permitted evidence of a temporary seven-day Protection From Abuse order which was received twelve years prior to the fire and another Protection From Abuse order received eight months after the fire. The admission into evidence of prior bad acts is within the sound discretion of the trial court, and we will reverse only upon a showing of an abuse of that discretion.
Commonwealth v. Miles,
Failure to Call an Alibi Witness
¶ 22 Appellant next argues that trial counsel was ineffective for failing to call an alibi witness. He contends that these witnesses would have supported other testimony as to the timing of the fire and his whereabouts on that night. To obtain relief as to .a missing witness claim, appellant must establish that (1) the witness existed; (2) the witness was available to testify; (3) counsel was informed of the existence of the witnesses where counsel should otherwise have known of him; (4) the witness was prepared to cooperate and testify for appellant at trial; and (5) the absence of the testimony prejudiced appellant so as to deny him a fair trial.
Commonwealth v. Petras,
Failure to Raise Post Trial Motions on Trial Court’s Hearsay Determination
¶ 23 At trial, Trooper Brian Craig, a fire marshall who investigated the fire at Sandra Lilliock’s home, was called as a Commonwealth witness. During cross-examination, defense counsel attempted to show Trooper Craig’s police report to the jury on the court presenter. The trial court did not allow the admission of the report on the ground that it was hearsay, but it allowed defense counsel to cross-examine Trooper Craig extensively *246 regarding the contents of the report. During deliberations, the jury requested that they review the police report. The trial court ruled that the police report had not been admitted into evidence and the jury would have to use their recollection of the cross-examination of Trooper Craig to remember the contents of the report. Appellant now claims that the court erred in not admitting the report into evidence, and counsel was ineffective for failing to raise this issue in a post-trial motion.
¶ 24 “There is no question that the police report, as an' out-of-court statement offered to prove the truth of the matters asserted therein, constitutes hearsay.”
Jennings v. Dep’t of Transportation,
¶25 “Error is considered to be harmless where: (1) the error did not prejudice the defendant or the prejudice was
de minimus;
or (2) the erroneously admitted evidence was merely cumulative of other, untainted evidence which was substantially similar to the erroneously admitted evidence; or (3) the properly admitted and uncontradicted evidence of guilt was so overwhelming and the prejudicial effect of the error was so insignificant by comparison that the error could not have contributed to the verdict.”
Commonwealth v. Foy,
. Failure to Raise Post Trial Motions on Trial Court’s Limitation of Defense Witness’s Testimony
¶ 26 Appellant next claims that the court erred in limiting the testimony of defense witness, Dan Miele, an insurance adjuster. During cross-examination of Sandra Lilliock, defense counsel questioned her concerning a statement that she made to her insurance adjuster several days after the fire. Appellant attempted to demonstrate that the fire financially benefited Mrs. Lilliock. Appellant argues that Dan Miele’s testimony was necessary to establish that Mrs. Lilliock’s statements at trial contradicted her statements made to the insurance adjuster. Appellant claims that if permitted to continue with his testimony, Mr. Miele would have testified that Mrs. Lilliock indicated that she did not intend to stay in the trailer.
¶ 27 The trial court has broad powers with regard to the admission or exclusion of evidence.
Commonwealth v. Kunkle,
Failure to Raise Post Trial Motions on the Inflammatory Closing Remarks by the Prosecutor
¶28 Appellant claims that during closing arguments, the prosecutor .made the following inflammatory remarks that prejudiced appellant: (1) the prosecutor centered his closing remarks around appellant’s prior Protection From Abuse violations and his previous relationship with his wife; (2) the prosecutor elaborated as to why Jay Whitfield would be inclined to fabricate his testimony for appellant; and (3) the prosecutor made a remark about appellant’s brother not attending the trial. We note that appellant has failed to cite to the record. Such omissions generally preclude review of this issue.
Commonwealth v. Rozanski,
¶ 29 The standard when reviewing challenges alleging prosecutorial misconduct is well established:
Every unwise or irrelevant remark made in the course of a trial by a judge, a witness, or counsel does not compel the grant of a new trial. Rather the focus is on what if any effects the comments had on the jury. A new trial is required when the effect of the District Attorney’s comments “would be to prejudice the jury, forming in their minds fixed bias and hostility towards the defendant so that they could not weigh the evidence objectively and render a true verdict.”
Commonwealth v. Faulkner,
¶ 30 Firstly, as discussed above, the evidence concerning the relationship of appellant and his spouse and the prior Protection From Abuse orders was relevant and was properly admitted. Thus, the prosecutor’s comments during closing arguments were appropriate. Secondly, the prosecutor’s remarks regarding the veracity of Jay Whitfield was a proper argument regarding the witness’s credibility. Finally, we have reviewed the prosecutor’s remark regarding the absence of appellant’s brother from trial, and we find that, given appellant’s closing argument, the remark was a proper statement and was not prejudicial to appellant. Thus, counsel was not ineffective for raising this meritless claim.
¶ 31 Accordingly, judgment of sentence is affirmed.
