Police Found His DNA 40 Years Later—He Was Already in Prison

The Ruby Battee cold case remained unsolved for 40 years until DNA evidence linked a convicted murderer to her 1986 killing in Dallas, Texas. In May 2026, investigators used modern forensic DNA testing and the CODIS database to identify Marvin Lee Holloway as a suspect. But detectives discovered something unexpected—Holloway was already serving a life sentence for another murder. Evidence preserved for four decades had finally produced a breakthrough. Holloway was subsequently charged with capital murder in Ruby Battee's death.
