Edward Dowell, 30, was one of four people shot execution-style in a Bethel, Ohio home on July 5, 1981. He had been visiting his brother-in-law, fireworks dealer Billy Stevenson, when Stevenson, his wife Lynda, their 5-year-old son Billy Jr., and Dowell were all killed and the house was set on fire. Authorities suspected robbery as a motive and brought in the Clermont County Sheriff’s Department, the state fire marshal’s office, and the state Bureau of Criminal Identification to investigate.

No suspects were immediately identified. A 17-year-old, Tony Noe, was charged with arson in a separate explosion at Stevenson’s fireworks stand a few days earlier; officials did not confirm whether that incident was connected to the murders while they investigated. The killings and the child victim shocked the community, and investigators continued to pursue leads.

If anyone knew Edward, the Stevenson family, or saw suspicious activity in Bethel around July 1981, please share what you know.
