The man who carried out one of the deadliest U.S. mass shootings escaped from a mental health facility in 2012, the same year he was convicted by a U.S. Air Force court-martial of domestic abuse, according to a police report.

Devin Kelley, who massacred 26 people at a church in rural southeastern Texas on Sunday, was convicted of assaulting his first wife and stepson while serving in the U.S. Air Force in 2012, according to the Pentagon.

That same year he briefly escaped from a mental health facility in Santa Teresa, New Mexico, according to an El Paso, Texas, police report.
