MILWAUKEE — A Milwaukee Police officer who was driving home after work died after another driver ran a red light and crashed into his car at 1:35 a.m. Tuesday, according to Police Chief Alfonso Morales.

The officer, Kou Her, a two-year veteran of the Milwaukee Police Department, died at Froedtert Hospital after a crash at North 60th Street and West Capitol Drive, Morales said at a press conference Tuesday morning.

The officer was southbound on North 60th Street when a westbound car on West Capitol Drive crashed into his vehicle, Morales said. Witnesses reportedly told police the other driver was speeding and ran a red light; the other driver fled.

Morales said witnesses stayed on the scene and told police what direction the suspect fled. Officers caught up to the suspect and arrested him, a 34-year-old Milwaukee man with four previous operating while intoxicated convictions, Morales said.

The man was still on probation from his fourth OWI, Morales said. Morales did not indicate whether he was suspected to be intoxicated in Tuesday's crash.

"I want the residents of this city to know and to appreciate the work that's done by our police officers," Milwaukee Mayor Tom Barrett said at the press conference. "Officer Her had just completed his tour of duty and like all of us wanted to drive home safely. Because (of) a person running a red light, he is now no longer with us."

The Wisconsin State Patrol is investigating the crash.

Officer Her is survived by his wife, six brothers, two sisters and parents.
