On November 16, 1983, Sheri Jo Elliot vanished after she didn’t make it home from school. Recently, police have used DNA evidence to finally identify her killer.
WASHINGTON — Michigan authorities revealed on Wednesday that they have cracked the 43-year-old case of a teenager’s murder. Her lifeless body was found four days following her disappearance on her usual route home from school.
Michigan State Police, in a recent social media update, shared that the case involving 16-year-old Sheri Jo Elliot’s kidnapping and murder had remained unsolved for decades.
As per police reports, Elliot went missing on November 16, 1983, after she failed to return to her home in Flint, Michigan. She was last seen waiting for the bus, but a thorough search near the bus stop yielded no clues.
Her body was discovered four days later, lying along a rural road in Blumfield Township, approximately 35 miles north of Flint.
Investigators confirmed that Elliot had been sexually assaulted and shot multiple times.
Evidence was collected from the site where she was found, but police were unable to match any of it to a suspect.
A stalled investigation gets new life 40 years later
Investigators in 1983 ran out of leads, and the case went dormant because forensics at the time were limited. DNA testing for criminal cases would first be used in England three years after Elliot’s murder, but the then-groundbreaking technology didn’t become a commonly-used tool in the U.S. until the early 2000s.
“Despite extensive efforts, the case went cold due to limited forensic technology available at the time,” Michigan State Police investigators said in their Wednesday announcement.
But the case was reopened in 2023, exactly 40 years after Elliot’s murder, with the hope that new technology could find her killer.
State police partnered with Othram Labs, a private DNA sequencing company, to develop a genetic profile of the killer based on DNA left at the scene.
That DNA profile led investigators to 75-year-old Roni Collins of Grand Blanc, Michigan.
Police said investigators had hoped to obtain a voluntary DNA sample from Collins to compare against their profile, but he died by suicide in January 2026 before that could happen.
DNA obtained during his autopsy was found to be a match to the sample from the crime scene, police said, identifying him as the person responsible for Elliot’s 1983 murder.
“Although Collins will not face prosecution, detectives believe the identification provides long-awaited answers to Elliott’s family and the community,” MSP said in a statement.
