OPINION BY
¶ 1 Appellant, the Commonwealth of Pennsylvania, appeals from the order entered in the Lebanon County Court of Common Pleas, which granted Appellee, William Padillas, a new trial. We reverse and remand for re-sentencing.
*360 ¶ 2 The relevant factual and procedural history of this case is as follows. On August 1 and August 9, 2006, the Lebanon City police set up two controlled drug buys using a confidential informant (“Cl”). The drug buys occurred at 372 North 12th Street, Lebanon City, Pennsylvania, where Appellee lived with his parents and brother, Daniel Padillas, among others. On November 13, 2006, the police arrested Ap-pellee and charged him with two counts of delivery of a controlled substance arising out of both controlled buys. 1
¶ 3 On June 4, 2008, the court held a jury trial. The Cl testified he had gone to 372 North 12th Street and purchased cocaine from Appellee on August 1 and August 9, 2006. The Cl stated he had known the Padillas family, including Appellee and his brother, Daniel, for approximately twenty (20) years, and had, at one point, lived with the family. Appellee’s mother, father, and Daniel, testified on Appellee’s behalf. Mr. and Mrs. Padillas testified Appellee did not use or sell drugs. They also testified Appellee left to drive to New York City before the Cl arrived at the house on August 1, 2006. Appellee’s mother testified she was in Florida on August 9th. Appellee’s father testified he could not remember where he was on August 9th.
¶ 4 Daniel testified he was at home with some friends on August 1st. The Cl came to the house, approached Daniel, and asked if Daniel could help him get some drugs. Daniel told the Cl he would see what he could do. Daniel went upstairs. The Cl remained downstairs talking with the friends, but soon followed Daniel up to his room. 2 In Daniel’s room, the Cl pulled a bag of cocaine out of his mouth, and both Daniel and the Cl did a line of cocaine. The Cl put the remaining cocaine into a different bag and left. Daniel believed one of his friends had sold the drugs to the Cl on August 1st, but said the Cl had previously brought drugs to the house and often carried the drugs in his mouth. Daniel testified he had done drugs with the Cl “quite often.” (N.T. Trial, 6/4/08, at 83; R.R. at 106). Daniel stated the Cl would come to the Padillas residence to see Daniel, and Appellee would avoid the Cl when the Cl was at the house. Daniel said his brother did not use or sell drugs. Daniel testified he could not remember where he was on August 9th, but there were usually a large number of people at the house.
¶ 5 Appellee testified he did not like the Cl and tried to avoid the Cl as much as possible. The Cl would come over to the house to see Daniel. Appellee knew Daniel used cocaine and would do drugs with the Cl. On August 1st, Appellee, his girlfriend, and his children left around 1:00 p.m. to drive to New York City. Appellee could not remember exactly where he was on August 9th, but he was probably at home. Appellee said he did not at any time sell drugs to the Cl, use drugs, or deal drugs. On cross-examination, Appel-lee admitted he had pled guilty to possession of a small amount of marijuana with intent to deliver drug paraphernalia and had used marijuana. Appellee then explained he thought “drug” meant cocaine.
¶ 6 The jury convicted Appellee of one count of possession with intent to deliver (“PWID”) cocaine in relation to the August 9th incident. On October 22, 2008, the court sentenced Appellee to one (1) to *361 three (3) years to be served in county prison. That same day, Appellee filed a post-sentence motion seeking a judgment of acquittal, arrest of judgment, or a new trial based on the after-discovered evidence of his brother’s post-verdict confession to the August 9th drug sale. The court set a hearing date on the motion. At the hearing, the court apprised Daniel of his constitutional right against self-incrimination and his right to counsel. Daniel decided to seek the assistance of counsel before testifying. The hearing was continued to January 13, 2009.
¶ 7 At the January 13, 2009 hearing, Daniel testified his friends sold the Cl cocaine on August 1st, but he sold the Cl cocaine on August 9th. Daniel stated he had not admitted his role before because he was “too scared” but decided to come clean as he did not want his brother to go to jail for something Daniel had done. (N.T. Post-Sentence Motion Hearing, 1/13/09, at 7; R.R. at 150). Daniel agreed the Cl would not confuse Daniel and Ap-pellee “unless he wanted to.” (Id. at 10; R.R. at 153).
¶ 8 On April 8, 2009, the court denied Appellee’s motion for judgment of acquittal and arrest of judgment, but granted Appellee a new trial. On April 27, 2009, the Commonwealth filed a notice of appeal. The court did not order the Commonwealth to file a concise statement of matters complained of on appeal pursuant to Rule 1925(b), and the Commonwealth filed none.
¶ 9 The Commonwealth raises one issue for our review:
WHETHER THE TRIAL COURT ERRED IN GRANTING [APPEL-LEE] A NEW TRIAL BASED UPON AFTER-DISCOVERED EVIDENCE?
(Commonwealth’s Brief at 4).
¶ 10 “When we examine the decision of a trial court to grant a new trial on the basis of after-discovered evidence, we ask only if the court committed an abuse of discretion or an error of law which controlled the outcome of the case.”
Commonwealth v. Bonaccurso,
¶ 11 Initially, the Commonwealth argues the law does not recognize a “de facto” invocation of the constitutional right against self-incrimination. The Commonwealth asserts the Fifth Amendment could render Daniel’s testimony unavailable only if he had explicitly invoked it, as the privilege applies to those who decline to respond to certain inquiries but does not extend to mere silence. The Commonwealth submits the court erred when it decided that Daniel must have intended to invoke the privilege at Appellee’s trial, just because Daniel said nothing at the time of his alleged involvement in the offenses. The Commonwealth maintains Daniel’s post-trial admission should have been deemed “available” at the time of Appel-lee’s trial. The Commonwealth claims the court should have further evaluated whether Daniel’s “presumed” claim of privilege was justified rather than simply assuming the Fifth Amendment would have protected Daniel’s testimony.
*362 ¶ 12 The Commonwealth also argues Ap-pellee failed to exercise due diligence in discovering this exculpatory evidence. The Commonwealth notes Appellee first told the police at the time of his arrest that his brother had sold the drugs and “it happened before”; yet Appellee failed to question Daniel or his family members about Daniel’s possible involvement. The Commonwealth asserts Appellee had a duty to develop Daniel’s role in the drug sales if Appellee believed his brother was involved in those sales. The Commonwealth maintains Appellee was not relieved of this duty when Daniel denied involvement in the drug sales. The Commonwealth contends Appellee’s close relationship and regular contact with Daniel made it very likely Appellee could have discovered Daniel’s inculpatory statement in the exercise of due diligence.
¶ 13 Moreover, the Commonwealth states Daniel’s inculpatory statement is cumulative and offered solely to impeach the Cl’s trial testimony identifying Appellee as the perpetrator. Appellee challenged the Cl’s credibility at trial through the testimony of Appellee’s mother, father, and brother, and this challenge failed. The Commonwealth contends Appellee now offers Daniel’s confession to impeach the Cl; by granting Appellee a new trial, the court improperly gave Appellee this chance. Lastly, the Commonwealth contends the circumstances surrounding Daniel’s confession are so unreliable, it is unlikely the outcome of Appellee’s trial would be different. The Commonwealth concludes this Court should vacate the new trial order, reinstate the jury’s guilty verdict, and remand for re-imposition of the sentence. We agree.
¶ 14 The Fifth Amendment protects a witness from compelled self-incrimination and renders that testimony unavailable.
United States v. Doe,
[F]ar from being prohibited by the Constitution, admissions of guilt by wrongdoers, if not coerced, are inherently desirable. In addition to guaranteeing the right to remain silent unless immunity is granted, the Fifth Amendment proscribes only self-incrimination obtained by a genuine compulsion of testimony. Absent some officially coerced self-accusation, the Fifth Amendment privilege is not violated by even the most damning admissions. Accordingly, unless the record reveals some compulsion, ... incriminating testimony cannot conflict with any constitutional guarantees of the privilege.
United States v. Washington,
*363
¶ 15 When a witness invokes his Fifth Amendment right against self-incrimination, the court must assess whether the witness’ fear of self-incrimination is reasonable, and not of an “imaginary and unsubstantial character.”
Ohio v. Reiner,
¶ 16 To be granted a new trial based on the basis of after-discovered evidence:
[Defendant] must demonstrate that the evidence: (1) could not have been obtained 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) would likely result in a different verdict if a new trial were granted.
Commonwealth v. Pagan,
¶ 17 To obtain a new trial based on after-discovered evidence, the petitioner must explain why he could not have produced the evidence in question at or before trial by the exercise of reasonable diligence.
Commonwealth v. Jones,
¶ 18 Before a court grants a new trial on the basis of after-discovered evidence, the defendant must also show the alleged after-discovered evidence is not just corroborative or cumulative of the evidence already presented at trial.
See Pagan, supra.
Whether new evidence is corroborative or cumulative in this context depends on the strength of the other evidence supporting the conviction.

monwealth v. McCracken,
¶ 19 Further, a defendant seeking a new trial must demonstrate he will not use the alleged after-discovered evidence solely to impeach the credibility of a witness.
See Pagan, supra.
“Whenever a party offers a witness to provide evidence that contradicts other evidence previously given by another witness, it constitutes impeachment.... ”
Commonwealth v. Weis,
¶ 20 Finally, before granting a new trial, a court must assess whether the alleged after-discovered evidence is of such nature and character that it would likely compel a different verdict if a new trial is granted.
See Pagan, supra; Moore, supra.
In making that determination, a court should consider the integrity of the alleged after-discovered evidence, the motive of those offering the evidence, and the overall strength of the evidence supporting the conviction.
Parker, supra
(stating conflicting accounts are inherently unreliable and would not compel different verdict in new trial).
See also Commonwealth v. Washington,
¶ 21 A statement against penal interest is often considered trustworthy if it subjects the declarant to criminal liability and a reasonable person would not make the claim unless it was true.
Randolph, supra
at 587-88,
¶ 22 In the instant case, the court found Daniel had “de facto ” invoked his Fifth Amendment right to remain silent when testifying at Appellee’s trial, because Daniel could have invoked the Fifth Amendment if asked about his role in the drug sales. Therefore, the court concluded Daniel’s belated confession constituted “unavailable” evidence at Appellee’s trial. The court found Daniel’s confession was not cumulative or corroborative of the trial evidence because Daniel’s confession fully exculpated Appellee. The court found Daniel’s confession reliable because it was a statement against Daniel’s penal interest. The court summarily concluded Daniel’s statement was not solely to impeach the Cl’s identification testimony and would likely change the verdict if the jury believed it. Respectfully, we disagree with the court’s analysis.
¶ 23 Here, Daniel voluntarily testified at Appellee’s trial on Appellee’s behalf. Appellee questioned Daniel about the events of August 1st, but asked Daniel no questions about the August 9th incident. Daniel stated he did not remember what happened on August 9th. At no point was Daniel asked about his possible involvement in the drug sales. The court erred as a matter of law when it simply inferred the unavailability of Daniel’s confession, given the absence of questions about potentially incriminating topics, simply because Daniel could have invoked his *367 rights if asked incriminating questions. See Washington, supra. Thus, Daniel was not subjected to compelled self-incrimination at Appellee’s trial and had no need to invoke his constitutional rights. See Doe, supra. Therefore, we conclude Daniel’s testimony was “available” for purposes of Appellee’s trial. See Washington, supra; Morley, supra.
¶ 24 Moreover, Daniel’s confession fails the due diligence prong of the four-part test for after-discovered evidence. Appellee lived in the same home with Daniel throughout the relevant period. Appel-lee was aware his brother used cocaine, was friends with the Cl, and did drugs with the Cl. When the police arrested Appellee, Appellee even said they “probably had him confused with [Daniel], it happened before.” (See N.T. Post-Sentence Motion Hearing, at 13; R.R. at 156.) Based on these circumstances, Appellee knew or should have known, at or before trial, of Daniel’s possible involvement in the August 9th drug sale. Nonetheless, Appellee did not ask Daniel or any of his family members about Daniel’s connection to the drug sales or otherwise investigate that prospect. Further, Daniel voluntarily testified for Appellee at trial. Appellee did not ask Daniel about his role, if any, in the drug sales at issue. Appellee did not investigate an obvious, easily accessible source of information and provided no plausible explanation for this failure. The fact that Daniel had earlier said he “could not remember where he was on August 9th” does not relieve Appellee of his duty to investigate with reasonable diligence the exculpatory information Daniel waited until after trial to offer. In light of these circumstances, we conclude Appellee failed to act with reasonable diligence in discovering Daniel’s allegedly exculpatory evidence. See Chambers, supra; Parker, supra; Jones, supra; Johnson, supra.
¶ 25 Additionally, the nature and substance of Daniel’s confession is both corroborative and cumulative of the evidence presented at Appellee’s trial where the essence of his defense was that he did not commit the crimes in question. Further, the Commonwealth’s case against Appellee relied on the testimony of the Cl. The Cl had known Appellee and Daniel for approximately twenty years, and, as Daniel testified, could tell the brothers apart. The Cl consistently and positively identified Appellee as the seller of the drugs on August 9th. At trial, Appellee attempted to impeach the Cl’s testimony by showing bias arising out of the Cl’s affair with Appellee’s mother fifteen years ago and the purportedly hostile relationship between the Cl and Appellee thereafter. Appellee’s mother, father, and Daniel all testified that Appellee did not use or sell drugs and did not associate with the Cl. Daniel’s post-verdict confession is therefore cumulative and corroborative of the trial testimony exonerating Appellee. See Rivera, supra; Nocero, supra. As the Cl testified for the Commonwealth at Appel-lee’s trial and unequivocally identified Ap-pellee as the perpetrator, Daniel’s later confession directly contradicts the Cl’s trial statements. Thus, the confession impeaches the Cl. See Weis, supra; Moore, supra. Therefore, Daniel’s confession is cumulative, corroborative, and offered solely for impeachment purposes. See Pagan, supra.
¶ 26 Finally, Daniel confessed only to the drug sale for which the jury had convicted his brother. There is no evidence corroborating Daniel’s claimed role in the August 9th drug sale. Also, the close sibling relationship between Daniel and Appellee gave Daniel strong reason to fabricate a confession clearing his brother. See Randolph, supra; Parker, supra. The trial court found Daniel’s confession *368 reliable solely because it was a statement against Daniel’s penal interest, without testing Daniel’s motive or considering whether the circumstances surrounding the confession indicated it was trustworthy. See Parker, supra. Daniel’s close relationship with Appellee gave Daniel an obvious motive to fabricate his confession. See Weichell, supra. Further, Daniel’s confession is a complete recantation of his testimony at Appellee’s trial, and the court should have viewed it as suspect even if the confession subjected Daniel to prosecution. 5 See McCracken, supra. Given our review of the entire record and the dubious circumstances surrounding Daniel’s confession, we cannot say that a new jury presented with all the evidence including Daniel’s confession would likely reach a different verdict upon retrial.
¶ 27 Based upon the foregoing, we conclude the court erred in granting Appellee a new trial due to the alleged after-discovered evidence of Daniel’s confession. See Pagan, supra. Accordingly, we reverse the order granting Appellee a new trial, and remand the case for reinstatement of the jury verdict and re-sentencing.
¶ 28 Order reversed; case remanded for re-sentencing. Jurisdiction is relinquished.
Notes
. 35 P.S. § 780-113(a)(30).
. On direct examination, Daniel testified he and the Cl went upstairs at the same time; however, on cross examination, Daniel testified he went upstairs, while the Cl remained downstairs talking with Daniel’s friends. Daniel later stated the Cl purchased drugs from one of Daniel's friends, outside of Daniel's presence.
. The Court’s reference to “reputation” means the privilege protects the witness against compelled self-incrimination in criminal conduct as well as protection from answering questions that would bring the witness social "disgrace or infamy.” See
Commonwealth v. Swinehart, 541
Pa. 500, 512-13,
. The federal courts distinguish between evidence which was previously unavailable and evidence previously undiscovered, for the purposes of Federal Rule of Criminal Procedure 33 (governing motions for a new trial based on newly-discovered evidence). A majority of federal circuits have concluded evidence known but unavailable at trial, including evidence unavailable due to a witness' invocation of the Fifth Amendment, does not constitute "newly discovered evidence” within the meaning of Rule 33.
United States v. Owen,
. If Daniel were later tried on charges arising from the August 9th drug sale, he could use the Cl's earlier identification of Appellee as a cause for reasonable doubt.
