Sherry Lynn Quinn was 17 when she told her family on September 5, 1980, that she was going to an acquaintance's place in the Dale City/Woodbridge area to pick up some of her things. She never came home. Weeks later a family member took a collect call from her that seemed to come from somewhere in Texas, and that was the last time anyone heard from her.

The hardest part of this case is the 41 years in between. No formal missing person report was opened until Prince William County police did it in 2021, so there was never a search, flyers or news coverage when people's memories were fresh.

She was about 5'3" with brown hair and brown eyes, and friends sometimes called her "Frizz." She was known to hitchhike, sometimes long distances. Who was the acquaintance she was going to see? If you knew Sherry in Dale City or Woodbridge in 1980, that's the person investigators most need to hear about.
