On Valentine's Day in 1985, college senior Terry Dolowy went missing from a mobile home near Barre Mills, Wis., some time after a late night shift at Piggy's Restaurant in downtown La Crosse.
Four days later, Mike Weissenberger, now retired from the La Crosse County Sheriff's Department, was one of the officers who responded after a report of a glowing object in a ditch along a rural Wisconsin road.
There, they found the burning and decapitated body of the 24-year-old woman.
Weissenberger is one of dozens of investigators from several agencies who have done thousands of interviews and spent a large part of their careers trying to find Dolowy's killer.
Now, he's hoping that the crime can be solved.
Dolowy's exhumed body was brought to the Minnesota Regional Medical Examiner's Office in Hastings on Friday, where a crowd of investigators -- including a forensic anthropologist from Hamline University's Anthropology Department, and the Cook County medical examiner from Illinois -- did an autopsy in hopes of finding what, and who, killed her.
By day's end, the body was sent back to Illinois for reburial, said Dr. Lindsey Thomas, who heads the regional office.
"Exhumations are very rare," Thomas said. "I've done maybe two or three in 20 years. It's an unbelievable case because there was no scene, no mess and her head was never found."
