The bodies were found in a burning dumpster in Fort Worth in 2021.
The Tarrant County jury found Jason Thornburg, 44, guilty of capital murder last month in the deaths of David Lueras, 42, Lauren Phillips, 34, and Maricruz Mathis, 33. According to his arrest warrant, Thornburg confessed to police about the killings.
“He is evil,” prosecutor Amy Allin told jurors.
According to Thornburg’s arrest warrant, he also told police he had killed his roommate and girlfriend.
The roommate, Mark Jewell, 61, was found dead in a house fire earlier that year. Thornburg’s girlfriend, Tanya Begay, a Navajo woman from Gallup, New Mexico, went missing after taking a trip to Arizona with Thornburg in 2017.
