On Wednesday, the jury heard from a prosecution cell-phone expert who testified about the last movements of O’Keefe’s cell phone, and from a Massachusetts State Police trooper about physical evidence recovered at the scene of O’Keefe’s death. The prosecution will call its next witness when the trial resumes Thursday at 9 a.m.

A new witness is set to testify after an expert told jurors when a star witness for the prosecution searched how long it takes to die in the cold.
