Christine Gallegos had plans to start a family with her fiance when she was found shot to death in 1985, police and family in Utah said. She was 18 years old, and for four decades her killing remained unsolved — until now, the Salt Lake City Police Department said in a May 15 news release, nearly 40 years to the day of her body being found.

The person believed responsible for sexually assaulting and killing 18-year-old Christine Gallegos in 1985 died of natural causes in 2023, police said.
