A body discovered near the Surrey Ridge exit off Interstate 25 in Douglas County, Colorado, on July 25, 1988, was identified as 25-year-old Diane Montoya Mancera, a Hispanic woman. An autopsy showed she had been strangled to death. At the time of her killing, Mancera was known to have been involved in prostitution in the Aurora area.

Her murder became part of a wider investigation into a string of similar killings of women who were involved in sex work. Police eventually arrested Vincent Darrell Groves on September 1, 1988, in connection with multiple murders; DNA recovered from Mancera’s body was cited as linking him to her death. Groves was convicted in 1990 of the murder of Juanita Becky Lovato and received a life sentence, and he was later given an additional 20-year sentence for Mancera’s death.

Groves was suspected in the deaths of at least seven women, with some investigators estimating as many as twenty victims. Does anyone have information about Mancera’s life in Aurora or about sightings around July 25, 1988?
