“Incendiary devices” were found at a Jehovah’s Witness hall following the apparent murder-suicide of a married couple there on Christmas Day, according to Colorado police.
“An adult female was shot and killed by an adult male, who then shot and killed himself,” the police said in a statement Sunday.
Police in Thornton, which is about 10 miles north of Denver, said the two were former members of the congregation.
Officers were originally called to the scene after reports of a fire.
The devices at the scene were rendered safe, police said, adding there were no additional suspects.
“No other people were injured as a result of this incident,” the police said.
The identities of those killed will be released later by the Adams County Coroner’s Office, the police added.
“This kind of violence is always shocking but particularly on Christmas Day,” Thornton Mayor Jan Kulmann said in a statement on Twitter.
