WIXOM, Mich. (AP) — A person of interest has been taken into custody in connection with dozens of shootings across four Michigan counties that resulted in at least one injury, authorities said Tuesday.

Ingham County Sheriff Gene Wriggelsworth told The Associated Press that authorities executed a search warrant late Monday night in Wixom, the Detroit suburb where the shootings began last month.

"We're trying to confirm whether he's our guy or not," Wriggelsworth said.

A tip — one of close to 3,000 that have come in — led authorities to the person, he said.

Asked for more details on the execution of the search warrant, the sheriff said: "We'll have to see how this shakes out."

The shootings began Oct. 16 and stretched from Oakland County west to Ingham County. The targets in the 24 reported incidents were mostly cars traveling on roads near Interstate 96. Only a handful of shootings actually occurred on the interstate.

Before Tuesday's development, clues appeared to be few: slugs and bullet fragments embedded in cars, metal casings on roadways, a simple black-and-white sketch of the shooter — a man believed to be in his late 20s or early 30s — and vague descriptions of the dark car he drove.

The crime scene where the shootings took place is 100 miles long and slices through suburbia, shopping malls and farm pastures. Shootings have occurred during the day, at night, on weekdays and on weekends. Police say the shooter drives along roadways and fires at vehicles traveling in the opposite direction.

So far, only one person has been wounded.

Initial reports of shootings stirred panic. Wixom schools restricted recess and other activities that would take students outdoors. Drivers avoided main thoroughfares where they might be exposed and took to driving along side streets.

But police have been working hard to maintain calm. In Wixom — where 10 of the shootings have been reported — police planned special Halloween patrols to protect trick-or-treaters. From Oakland County, northwest of Detroit, to Shiawassee County, northeast of Lansing, authorities stopped cars resembling the shooter's vehicle.

A $102,000 reward is being offered for information.
