Appearing:

Video expert testimony addressed surveillance-footage limits before Bryana Bongolan testified about an alleged balcony incident; her cross-examination continued to the next morning.

Full day summary

The court resolved evidentiary issues before the jury entered, including overruling a Rule 403 objection to the government's video compilation and entering an immunity order for Bryana Bongolan. Forensic video expert Frank Piazza testified about cellphone and surveillance recordings, including playback-speed corrections, timestamp limitations, and apparent gaps in the surveillance footage; the court admitted his chronological compilation. Bongolan then testified about an alleged balcony incident involving Sean Combs and identified photographs she said showed injuries. On cross-examination, the defense questioned her about prior accounts, civil litigation, drug use, and differences in descriptions of the balcony and knife incidents. The jury was excused before cross-examination concluded, and it was set to continue the next morning.
