Alabama authorities made a second arrest in a deadly 2017 home invasion after obtaining DNA testing results from a mask left at the crime scene.

AL.com reported that Jefferson County police arrested Jason Dale Boatwright, 40, on August 22 for the September 15, 2017, home invasion that left Stephen Douglas Crump, 38, dead. Police said Boatwright and Crump, both armed, barged through a door at a Mulga home—leading the homeowner to fatally shoot Crump in the head.

Crump was pronounced dead at the scene. The alleged getaway driver, Horace D. Stokes, 39, was arrested shortly after the botched break-in and charged with murder for Crump’s death. Stokes remains jailed, awaiting trial.

Boatwright’s mask reportedly fell off as he fled the home. WFSA reported that the mask was sent to the Alabama Department of Forensic Sciences for DNA testing. From there, the DNA was run through the Combined DNA Index System (CODIS) for a match. The system includes forensic data registered by state, federal, and local laboratories, potentially allowing authorities to link crimes to offenders entered in the database.

The news station reported that on August 15, the Alabama Department of Forensic Sciences informed Jefferson County detectives that DNA from the mask matched Boatwright. He’s currently charged with murder, first-degree robbery, first-degree burglary, and second-degree assault. He’s being held without bond.
