Former Minneapolis police officer Derek Chauvin's murder trial is continuing its second week. Chauvin, who is charged with second-degree murder, third-degree murder and second-degree manslaughter, has pleaded not guilty.

An expert witness testified Tuesday that officers used excessive force against George Floyd during his fatal May 2020 arrest. LAPD Sergeant Jody Stiger, an expert in tactics and de-escalation training, reviewed the case and testified for the prosecution.

"My opinion was the force was excessive," Stiger said.

Stiger is expected to return to the stand Wednesday to continue his testimony.
