Investigators are looking for a 31-year-old man they said stabbed a man and woman early this morning during a fight in a 7-Eleven store parking lot at Hewitt and Ellsworth roads in Ypsilanti Township.

The two victims, both 31 and from Ypsilanti, sustained non life-threatening injuries in the stabbing, which occurred about 12:50 a.m., Washtenaw County Sheriff's Department Sgt. Tom Pennington said.

Deputies responded to a fight involving five to six people, and, when they arrived on scene, saw a vehicle leaving the area, Pennington said. Officers followed the vehicle to St. Joseph Mercy Hospital in Superior Township, finding the two victims inside.

Pennington said it's unclear what prompted the fight. The victims know the suspect, he said. Pennington said he did not know what was used to stab the victims.

Anyone with information can call the department's tip line at 734) 973-7711.
