Identification of the Suspect
Nearly 40 years after the murder of Rhonda Marie Fischer, the Douglas County Sheriff’s Office has identified Vincent Darrell Groves as the primary suspect. Fischer, a 31-year-old woman, was found dead on April 1, 1987, near Sedalia, Colorado. Investigators revealed that she had been sexually assaulted and strangled. Groves, who is considered one of Colorado's most prolific serial killers, is believed to be responsible for at least 12 homicides during a crime spree that lasted from 1978 to 1988. He primarily targeted vulnerable women, often hitchhikers, and was known to have been released from prison shortly before Fischer's murder.
Breakthrough in Forensic Evidence
The breakthrough in Fischer's case came when the cold case team revisited the evidence in February 2025. They decided to test paper bags that had been placed over Fischer's hands at the crime scene to preserve trace evidence. Remarkably, skin cells found on the bags matched Groves' DNA, which had been retained from previous investigations into his other crimes. This DNA match was confirmed through the Combined DNA Index System, a national database maintained by the FBI, and was reported to investigators in October 2025.
Historical Context of the Case
Fischer was last seen alive on March 31, 1987, walking in Denver. At the time of her death, Douglas County detectives investigated various acquaintances and serial offenders, including Groves, but lacked the forensic technology to make a definitive connection. Groves had been convicted of murder in 1982 but served only five years before his release. He was later incarcerated again for other murders and died in prison in 1996.
Official Statements & Responses
Douglas County Sheriff Darren Weekly emphasized the importance of advancements in forensic science in solving cold cases. He stated, “This case underscores our dedication at the Douglas County Sheriff’s Office to solving these cold cases and embracing new technologies.” The sheriff's office has successfully solved seven cold cases in the past seven years, with 35 remaining unsolved. Weekly reiterated their commitment to these investigations, stating, “As science evolves, so does our ability to uncover the truth.”
Criticism & Opposition
While the resolution of Fischer's case has been met with relief, some critics have raised concerns about the justice system's handling of Groves' earlier convictions. Questions remain regarding why Groves was released after serving such a short sentence for his initial murder conviction, especially given his history of violent behavior.
