The FBI has joined Michigan and local police in investigating three shootings involving vehicles on southeast Michigan roadways.
The shootings were reported Monday evening in Washtenaw County within roughly 15 minutes of each other. Police believe the shootings are related.
Two were in Bridgewater Township and one was in nearby Pittsfield Township, about 40 miles southwest of Detroit. No one was injured.
Pittsfield Township public safety director Matt Harshberger says investigators "do believe they're probably related."
FBI spokesman Simon Shaykhet says the agency is working with township, county, state and other federal authorities on the shootings. Investigators held a joint meeting Wednesday.
Authorities say they want help from the public in finding leads and evidence in the shootings.
