COLD CASE: SEEK CLUES ON 'JANE DOE 1973' - IDENTIFIED AFTER MORE THAN 50 YEARS

Weld County cold case detectives are seeking information on a dead California teen identified through forensic genealogy more than 50 years after her body was discovered in Colorado. Roxanne Colleen Leadbeater, 15, of Redondo Beach, California, was positively identified last December, according to the Weld County Sheriff's Office. Her body was discovered near the bank of the St. Vrain River, north of Highway 66 and four miles west of Platteville, on Nov. 19, 1973. Her remains were interred at Linn Grove Cemetery in Greeley as "Jane Doe 1973."

Six law enforcement agencies in the Los Angeles area have no record of the teen being reported missing or running away. The manner and cause of Leadbeater's death are unknown but considered suspicious.

The youth once lived on West 163rd Street in Lawndale, California - and attended Lawndale High School from 1971 to 1972. She was in the ninth grade. Her only known living relatives believe she went missing around 1972 and had no known ties to Colorado. A cousin provided a DNA sample.

Roxanne’s mother, Joan Kobayashi, deceased, lived in Maui, Hawaii. Roxanne’s father, John Leadbeater, also deceased, lived on 190th Street in Redondo Beach. Her brother, Bryant Leadbeater, died in Torrance, California, in September 1984.

The sheriff's office: "Detectives have released a photo of Roxanne during the time she attended Will Roger’s Junior High from 1970 to 1971 in the hopes classmates, friends, neighbors, or acquaintances will come forward with any information about Roxanne’s life prior to her death."

Leadbeater was born June 8, 1957, in Burlington, Vermont, according to the Find a Grave database.
