Senior Special Agent James Reyerson is the lead investigator for the case against Derek Chauvin in the death of George Floyd.
CHANLEY PAINTER: The state has called the Senior Special Agent of the newly formed Use of Force Investigation Unit of the Bureau of Criminal Apprehension here in Minnesota to the stand this afternoon. Now, James Reyerson is the lead investigator for the case against Derek Chauvin in the death of George Floyd.
JAMES REYERSON: So my supervisor called me at approximately 9:45, Agent Phil, and informed me there had been an incident that occurred in the confines of Minneapolis involving Minneapolis Police Department. It was determined that myself, Agent Phil, and Agent Scott Mueller would all report to City Hall.
MATTHEW FRANK: And so did you understand essentially why you, as BC agents, were being called to this incident?
JAMES REYERSON: We knew that some form of critical incident had occurred, but at that point, we didn't have a huge amount of information.
MATTHEW FRANK: And when you use the term "critical incident" in this context, what did it mean to you at that time?
JAMES REYERSON: An incident involving a police officer and potentially a civilian that could have caused harm.
CHANLEY PAINTER: During Reyerson's testimony, prosecutors showed a series of video clips from bystander video, body camera video, and surveillance video. And earlier today, an expert, Sergeant Jody Stiger, offered his opinion on the level of force Derek Chauvin was using on George Floyd May 25, 2020. That's the latest from here.
