MILWAUKEE (WTAQ) - Police and prosecutors in Milwaukee continue to investigate the weekend shooting death of a robbery suspect by a city police officer.

Officials said a 28-year-old man from Germantown robbed another man late Saturday afternoon and then drove away.

The robbery victim followed the suspect and called police – and the suspect ran off after crashing his vehicle.

An officer later tracked down the suspect. Officials said the patrolman was trying to interview the suspect when the officer felt his life was in danger – and he shot the man.

Witnesses told TV reporters that they heard 4 gunshots, and one report said the suspect was unarmed.

Milwaukee Police said the alleged robber was on probation, and he wanted for felony escape and violating a previous probation.

The officer is a 15-year Milwaukee Police veteran. He’s on administrative duty while the shooting is being investigated.
