Jefferson County John Doe was a young teenage boy or young man whose arm bone and pelvis were found on August 9, 1973 in Jefferson County, Texas. He is believed to be a victim of Dean Corll and his accomplice Elmer Henley Jr., and David Brooks.
On August 8, 1973, Henley called the Houston Police Department after he shot and killed Corll in a dispute. He confessed to them about their and Brook's involvement of the serial killings known as the Houston Mass Murders. Between 1970 and 1973, Corll, Henley, and Brooks abducted, raped, tortured, and killed at least twenty-eight young boys and teenage men. Henley and Brooks showed police where they buried their victims, which included a boat shed in southwest Houston, Texas, Lake Sam Rayburn, and High Island Beach. This victim's remains were found with the twenty-seventh and twenty-eighth victim in High Island Beach.
Henley is currently imprisoned at the Mark W. Michael Unit for nine of the murders and David Brooks was incarcerated for one of the murders at the Ramsey Unit until his death from COVID-19 on May 28, 2020.
Although the Houston Police Department at the time believed Corll, Henley, and Brooks killed twenty-eight victims, various pieces of testimony and evidence suggests they killed more boys and young men. The presence of this victim's bones suggests an additional twenty-ninth victim who is not counted on the official list.
