A defendant who intends to offer the defense of alibi at trial shall file with the clerk of courts not later than the time required for filing the omnibus pretrial motion provided in Rule 579 a notice specifying an intention to offer an alibi defense, and shall serve a copy of the notice and a certificate of service on the attorney for the Commonwealth.
Within 10 days after receipt of the defendant’s notice of defense of alibi, or within such other time as allowed by the court upon cause shown, the attorney for the Commonwealth shall file and serve upon defendant’s attorney, or the defendant if unrepresented, written notice of the names and addresses of all witnesses the attorney for the Commonwealth intends to call to disprove or discredit the defendant’s claim of alibi.
If prior to or during trial a party learns of an additional witness whose identity, if known, should have been included in the notice furnished under paragraphs (A) or (C), the party promptly shall notify the other party’s attorney, or if unrepresented, the party, of the existence and identity of such additional witness.
No adverse inference may be drawn against the defendant, nor may any comment be made concerning the defendant’s failure to call available alibi witnesses, when such witnesses have been prevented from testifying by reason of this rule, unless the defendant or the defendant’s attorney shall attempt to explain such failure to the jury.
A defendant may testify concerning an alibi notwithstanding that the defendant has not filed notice, but if the defendant has filed notice and testifies concerning his or her presence at the time of the offense at a place or time different from that specified in the notice, the defendant may be cross-examined concerning such notice.
