Authorities said Friday that a Utah police officer allegedly killed four family members and himself in a quadruple murder-suicide, the Salt Lake Tribune reported.

Spanish Fork Police Chief Steve Adams told the newspaper that a commander from the Lindon, Utah police department called to ask the SFPD to check up on the alleged shooter, Joshua Boren, when he didn’t show up for work Thursday night.

Officers went to Boren’s home that night and said no one would answer the door, although it was unlocked. Once inside the home, police found the bodies of Boren, his mother-in-law, his wife and two children. The mother-in-law was dead from a gunshot wound.

Adams told the Tribune that investigators had not found any message or suicide note, although he said Boren had been experiencing marital problems.
