Michigan State Police Capt. Monica Yesh said the suspect's car matches the description of the black, four-door vehicle that witnesses saw, the Detroit Free Press reported Tuesday.
The suspect, whose name was not released, was taken into custody Monday night during a raid at a home in Wixom, Yesh said.
Three of the shootings occurred on I-96 while the rest happened on surface roads or other highways in Oakland, Ingham, Livingston and Washtenaw counties.
