A Texas man, who confessed to killing five people, was indicted on Monday on a capital murder charge. 

The dismembered bodies of three victims were found in a burning dumpster in west Fort Worth on September 22. Surveillance footage of a vehicle at the site of the dumpster led authorities to 41-year-old Jason Thornburg.

During interrogation, he confessed to killing the three people found in the dumpster. He also confessed to killing his roommate and girlfriend. The 41-year-old told the officers that he had in-depth knowledge of the Bible and believed he was being called to “commit sacrifices,” according to the arrest warrant.

Cops said that when they identified Thornburg as a suspect in the killing of the three found in the dumpster, they were already familiar with him from a suspicious death investigation earlier in the year. His roommate had been killed in a suspicious house fire in May.

During the interrogation in September, Thornburg told officers he had slit his roommate’s throat, then uncapped a natural gas line and lit a candle. At the time, the medical examiner had not been able to determine his roommate’s cause of death. When police asked Thornburg about any other crimes that he had committed, he said he also sacrificed his girlfriend in Arizona, according to the arrest warrant.
