Saginaw County Sheriff Bill Federspiel calls it a bizarre incident with two people in jail after a weekend I 75 shooting. Three people escaped injury after a man and woman in a second car fired an unknown number of shots at them on the Zilwaukee Bridge.

Federspiel says 30-year-old woman from northern Michigan called Saginaw County 911 about 3:30 a.m., Sunday, December 1, even though there was a misdemeanor warrant for her arrest. Federspiel thinks survival and facing arrest may be reason for calling the police for help.

The incident began in the southbound I 75 rest area just north of the Bay-Saginaw county line. It ended on the exit ramp to M 13, River Road.

Saginaw County Sheriff detectives believe a drug dispute may be involved as drug paraphernalia was found in both cars.

Investigators are seeking assault with intent to murder charges against a 30-year-old man and a 20-year-old woman. Both suspects are from Grand Traverse County. They face arraignment in Saginaw County District Court on Tuesday, December 3.

Two men and a woman from Kalkaska and Montcalm Counties were not injured by the gunfire.
