On December 15, 1986, workers maintaining the Amtrak railway tracks behind the Club House Diner on Street Road in Bensalem Township, Bucks County, Pennsylvania, discovered the skeletal remains of a young woman concealed in brush alongside the gravel railway bed. For thirty-seven years, she stood on the coroner's docket as "Bucks County Jane Doe."

Discovery, Railroad Corridor & Forensic Pathology

Forensic anthropologists estimated the decedent was a Caucasian female between 18 and 30 years old, standing 5 feet 0 inches to 5 feet 3 inches tall. She had been dead for approximately six months to two years before recovery. Cause of death was ruled a homicide.

At the scene, investigators recovered clothing fragments: blue denim trousers, a red-and-white striped shirt, and a distinct gray winter sweater. Despite extensive regional dental comparisons and fingerprint checks against Mid-Atlantic missing persons records, no matching profiles emerged.

The Othram Resolution & The Bensalem Homicide Hunt

In 2022, Bucks County District Attorney Matt Weintraub and Bensalem Township Police Detective Chris McMullin partnered with Othram Inc. to conduct Forensic-Grade Genome Sequencing on degraded skeletal samples. Othram's team constructed a comprehensive SNP profile that allowed genetic genealogists to construct family trees centered in nearby Philadelphia.

In late 2023, detectives contacted surviving siblings of Sherri Lee Cook, who was 23 years old when she vanished from her Philadelphia neighborhood in the mid-1980s. A reference DNA swab confirmed the match with absolute certainty.

With Sherri's identity established after nearly four decades, Bucks County detectives have launched a full-scale homicide investigation. Investigators are examining connections between Sherri's social circle in Philadelphia and the Amtrak railway corridor in Bensalem, seeking tips from anyone who knew Sherri Lee Cook between 1984 and 1986.
