DNA Links Paper Bags to Colorado’s Notorious Serial Killer in Fisher Case

After nearly four decades, authorities have identified a suspect in the 1987 murder of Rhonda Marie Fisher through groundbreaking DNA analysis. The Douglas County Sheriff’s Office confirmed a match to Vincent Darrell Groves, considered one of Colorado’s most notorious serial killers.

Historic Case Background

On April 1, 1987, Rhonda Marie Fisher’s body was discovered along a rural highway embankment near Sedalia, Colorado. She had been sexually assaulted and strangled. At the time, Fisher was last seen walking on a street in Denver, approximately 25 miles north of where her body was found.

Investigation Details

Initially, detectives explored leads involving Fisher’s acquaintances and other serial offenders active in the Denver area from the 1970s to the 1990s. Despite extensive investigative efforts, including a DNA testing strategy in 2017 that yielded no suspects, the case went cold.

Breakthrough with DNA Analysis

The Douglas County Cold Case Unit revisited the evidence earlier this year, focusing on two paper bags that had been preserved since Fisher’s murder. These bags were placed over her hands at the crime scene, and researchers believed they might contain residual skin cells.

• Paper bags preserved for 40 years provided critical evidence.
• DNA was not routinely used in 1987, highlighting the preservation effort.
• Expert Shane Williams noted the bags had not been touched, increasing the likelihood of successful DNA extraction.

Identification of the Suspect

The DNA results pointed to Vincent Darrell Groves, who was already a convicted killer by the time of Fisher’s murder. Groves, who died in prison in 1996, is linked to multiple murders in the Denver area from 1978 to 1988.

While it remains unclear how Groves encountered Fisher, he had previously been considered a possible suspect. However, it took the DNA confirmation to solidify his connection to the crime.

Impact on Victims’ Families

Despite the resolution of Fisher’s case, many family members, including her parents and brother, have passed away. Nevertheless, a cousin of Fisher expressed relief at finally receiving answers.

“Rhonda Fisher was a mother, daughter, sister, and friend,” stated Sheriff Darren Weekly. “This case exemplifies our commitment to pursue justice for every victim, regardless of the time elapsed.”

Advancements in Forensic Science

The case illustrates a broader trend, where law enforcement across the United States is utilizing advanced DNA technologies to solve cold cases. The Douglas County Sheriff’s Office noted that Fisher’s murder marks the seventh cold homicide solved in seven years, thanks to improvements in DNA analysis.

As forensic science continues to evolve, authorities are optimistic about uncovering more truths and bringing closure to families waiting for answers.
