A Detroit police officer was killed early Sunday in what authorities are calling a hit-and-run crash on the city's east side.

The officer, identified as Cameron Richardson, was driving home in a Jeep Wrangler after working a shift when a motorist allegedly attempted to make a turn into an intersection and hit the Jeep, causing it to roll, CBS reports.

The vehicle that hit the Jeep, described by witnesses as a white van, left the scene, but was found a short distance from the intersection, the Michigan State Police say. A firearm was reportedly found in the van.

The driver of the van, identified by authorities as a 28-year-old man, is not in custody. Police are in close contact with the man's family, and asking that he turn himself in.

Officer Richardson is survived by two daughters, ages 12 and 14, and his parents John and Mona.
