The Livingston County Sheriff's department believes that they have identified one suspect and possibly another in the 1990 disappearance of a 30-year-old substitute teacher.

Paige Renkoski's (pictured, left) car was left running along Interstate 96, and was last seen on May 24, 1990. Her purse was found inside of the car.

She left her home that morning to drive her mother to Detroit's Metro Airport, then stopped to visit a friend in Wayne County's Canton Township, according to reports.

After leaving her friend's house, she headed back to the Lansing area, investigators believe.

Renkoski is from Clinton County's DeWitt Township.

The two suspects are from Detriot and one of the men is already in prison, according to reports.
