This week marks the 12th anniversary of the disappearance of a Michigan girl.

The FBI and local police say they're renewing efforts to find Brittany Beers. She was 7 years old on Sept. 16, 1997, when she was last seen sitting on a bench near the apartment complex where her family lived.

Investigators tell WNDU-TV in South Bend, Ind., they're going back over the entire case to look for new leads. Sturgis is near the Indiana border, about 80 miles south of Grand Rapids.

Investigators say they hope the passage of time will make it easier for people with knowledge about Brittany's disappearance to break their silence and come forward.

Investigators ask people with tips to call Crime Stoppers at 800-342-STOP.
