The Washtenaw County Sheriff's Department says the target of a drug raid died after deputies used a stun gun to subdue him.
Sheriff's spokesman Derrick Jackson said Sunday that state police are investigating because deputies are involved.
Jackson says deputies were assisting with a drug raid Friday afternoon in Superior Township, about 30 miles west-southwest of Detroit.
He says 31-year-old Stanley H. Jackson fled into a house, then struggled with deputies, who used a stun gun in arresting him.
The spokesman says an emergency medical services crew was called as a matter of routine. He says the suspect was alert then and on arrival at St. Joseph Mercy Hospital but later died there.
