CINCINNATI -- Grant Fredericks, a video analyst expert, took the stand at about 12:30 p.m. Monday in Ray Tensing's retrial.
Fredericks continued until after 1:30 p.m., when court was adjourned for the day. He will continue Tuesday morning.
In Tensing's first trial, Fredericks gave a 45-minute scene-by-scene breakdown of Tensing's body camera footage.
David Lindenschmidt, Ray Tensing's former University of Cincinnati Police Department colleague, was first to testify on Day Three of the former officer's murder retrial. Next, a Cincinnati Police crime scene investigator Jimmy Pham -- who said he was the first investigator on the scene -- testified.
