New details released into Greenfield officer-involved shooting

GREENFIELD, Wis. (CBS 58) -- Greenfield Police Chief Jay Johnson on Tuesday, Aug. 24, spoke for the first time since an officer-involved shooting left an officer critically injured and the suspect dead.

Chief Johnson's message was posted to Greenfield Police Department's social media pages. He called it, "The most difficult time in the history of the Greenfield Police Department."

Police say it started around 1:30 Sunday morning, Aug. 22. Officers pulled over the suspect, 31-year-old Tyran Lamb. When backup officers arrived, Lamb took off but crashed his car a short time later at 27th and Becher.

A man started recording the incident on his cellphone shortly after the crash. It shows officers surrounding the car, ordering the suspect to show his hands.

"As officers approached the vehicle to take the subject in to custody and check on the welfare of those involved, the suspect fired a weapon from inside the vehicle at both officers," Chief Johnson said.

Chief Johnson says Lamb got out of the car, still shooting and ran. The shootout can be heard on video as the man filming ducks for cover.

"One of the officers was found to have several gunshot wounds," Chief Johnson said. "The backup officer performed life saving measures."

Lamb was also shot; police found him nearby. The cellphone videos shows officers performing CPR but Lamb was pronounced dead on the scene.

The officer remains in critical condition.

"We have along road ahead of us, of recovery," Chief Johnson said. "Our officer is still fighting for his life at Froedtert."

Chief Johnson says the entire incident was recorded on body cameras and dash cameras. Those videos have been turned over to the Milwaukee Police Department, which is leading the investigation.
