Mark Jewell, a 61-year-old man from Euless, Texas, was found dead on May 21, 2021, after an explosion at the Fort Worth home he shared with roommate Jason Alan Thornburg. The Tarrant County Medical Examiner initially listed cause of death as thermal and blast injuries; the manner of death was later amended to homicide after Thornburg confessed during a police interview. Thornburg admitted to slitting Jewell’s throat, uncapping a natural gas line, and lighting a candle before leaving for work, which led to the fatal explosion.

Thornburg, 41, was indicted for murder and arson in Jewell’s death. His statements also linked him to other killings and raised questions about his mental state; a magistrate ordered a mental health evaluation during proceedings.

Did anyone in Fort Worth or Euless know Mark Jewell or have information about his relationship with his roommate?
