After assaulting his then-fiancé Nicarsia Jackson on two separate occasions, Willie Wright was convicted in the Circuit Court for Prince George’s County of two counts of second-degree assault and one count of reckless endangerment. On appeal, Mr. Wright challenges the circuit court’s decision to admit portions of three phone calls he made while in jail awaiting trial. The state of the trial court record leaves some doubt as to which portions of which phone calls were actually played for the jury, despite extensive efforts on the part of the parties to reconstruct it. For present purposes, we resolve those mechanical doubts in Mr. Wright’s favor—that is, we assume, notwithstanding real doubts, that the jury heard the challenged excerpts. Even so, we find that any alleged errors were harmless beyond a reasonable doubt, and so we affirm Mr. Wright’s convictions.
