MILWAUKEE (CBS 58) -- Milwaukee police are searching for a driver after a deadly hit-and-run crash Thursday morning, April 23. 

Officers responded to the scene near 13th and Vliet around 9:10 a.m.

Police say a driver struck the victim and fled; the victim was pronounced dead at the scene. 

People who live in the area say they believe the man who was killed lived in a tent nearby. They say they saw officers going door to door looking for video of the vehicle involved. 

We spoke with a man who lives across the street from the scene of the crash, who said he heard it happen. 

"Just heard a boom. I just thought - because there's a lot of bumps out there - I thought it was one of them," he said. "Nobody screamed. I look out the car, and I see the man laying on the ground."

An active investigation is underway. Anyone with information is asked to contact Milwaukee police at 414-935-7360, or to remain anonymous, call Crime Stoppers at 414-224-TIPS.
