2 shot on Southfield Freeway in west Detroit, state police say

Two people were wounded in a shooting Thursday night on the Southfield Freeway on Detroit's west side, Michigan State Police said.

The agency's 911 center was notified of the shooting on M-39 southbound lanes near Plymouth. Two victims were transported to St. Mary Mercy Livonia Hospital. 

An investigation revealed that the car was traveling south on the freeway near Schoolcraft "when a unknown vehicle pulled alongside and began shooting," state police said on Twitter.

The driver sustained a gunshot wound to the shoulder and a passenger sustained a gunshot wound to the knee, state police said Friday. A motive has not been determined.

It was the second reported shooting on the Southfield Freeway in 24 hours. On Wednesday, a man said he was driving a van north near the Interstate 96 ramp at about 10 a.m. when he saw "two cars traveling at a high rate of speed approach his vehicle," Michigan State Police said on Twitter, citing a preliminary investigation.

At the point where the local and express lanes split, one of the cars — a gray sedan — fired a shot, striking the van, state police said.

Thursday's incidentcame shortly after a shooting on I-75 in Detroit left one child dead and another wounded.
