Defendant also challenges the sufficiency of the evidence to support the convictions.
Finding no error, we affirm the trial court. The parties are fully conversant with the record, and this memorandum opinion recites only those facts necessary to a disposition of the appeal. Failure to make timely objection ordinarily constitutes a waiver. . . . Counsel cannot remain silent when improper argument is made and after the whole argument is concluded . . . Thus, defendant's motion, first made at the conclusion of the Commonwealth's opening statement, was clearly untimely.
