Texas church shooter Devin Patrick Kelley called his dad to tell him “he wasn’t going to make it” minutes before apparently shooting himself to death on a Texas highway.

Right after killing 26 people and injuring another 20 inside the First Baptist Church in Sutherland, Texas, Sunday morning — as he was speeding away from the crime scene with two good Samaritans in hot pursuit — Kelley “called his dad. He used a cellphone to tell him he didn’t think he would make it,” Freeman Martin of the Texas Department of Public Safety said during a Monday-morning press conference.

Kelley apparently killed himself moments later, officials said.

Investigators “found evidence at the scene indicates that the subject may have died form a self-inflicted gunshot wound,” Martin said.
