Read defense attorney cross-examines prosecution digital forensics expert SUV event, phone lock timeline

DEDHAM, Mass. (WLNE) — Karen Read defense attorney Robert Alessi continued his cross-examination of the prosecution’s witness, Shanon Burgess, in Read’s retrial Tuesday.

Burgess, a digital forensics expert, was introduced by the prosecution to explain a time discrepancy between the clock in Read’s SUV and victim John O’Keefe’s cell phone.

Read’s SUV registered an “event” within two minutes of O’Keefe’s phone being locked.

It would support the prosecution’s theory that read hit O’Keefe, knocked him to the ground, and then took off.

Burgess is trying to prove to the jury that O’Keefe’s clock was 30 seconds fast, and both incidents happened at the same time.

Alessi scrutinized Burgess’ calculations, saying that the data recorded on O’Keefe’s phone such as a phone lock occurred after the SUV’s trigger event, challenging his timeline.
