WIXOM (AP) -- Police agencies and federal agents in southeast Michigan are searching for a man responsible for shooting at two dozen vehicles along a busy interstate and nearby roads.
Officials with a task force say Wednesday that more than 2,200 tips have been received in the case that started with shootings Oct. 16 in Wixom, about 25 miles northwest of Detroit.
About 1,300 of 2,200 tips have come in since a reward was increased Monday from $12,000 to $102,000.
Only one motorist has been wounded in the shootings which have occurred in Oakland, Livingston, Ingham and Shiawassee counties.
Investigators are up against anonymity and a 100-mile-long crime scene. The clues appear to be few and include slugs embedded in cars and a simple sketch of the shooter.
