Sixteen-year-old Cynthia Rae Cadieux left her family’s home in Roseville, Michigan, on the evening of January 15, 1976, to visit a friend and vanished after leaving that house around 8 p.m. Her body was found about five hours later, at approximately 1:05 a.m., by a motorist on Franklin Road in Bloomfield Township. She was nude, her skull had been crushed by a blunt object, and her arms showed signs of having been bound; an autopsy later determined she had been raped and sodomized by more than one person.

Investigators later received a tip that led them to Raymond Heinrich Jr. and Robert Anglin and to the conclusion that Cynthia had been kidnapped, taken to a motorcycle club in Detroit, tied up, sexually assaulted by multiple men, and murdered. In 1979 Heinrich and Robert L. Anglin were convicted of first-degree murder and sentenced to life in prison. A third man alleged to have been involved died before he could be tried.

If anyone has memories of Cynthia, the motorcycle club, or the area around Franklin Road in 1976, please share what you know.
