BERMAN: All right, good morning, everyone. I'm John Berman.</s>HARLOW: And I'm Poppy Harlow. This morning the hero who shot the Texas church gunman tells his story. Listen to his humble account.</s>STEPHEN WILLEFORD, SHOT AND CHASED TEXAS CHURCH SHOOTER: I'm no hero. I am not. I think my God, my Lord, protected me and gave me the skills to do what needed to be done. And I just wish I could have gotten there faster.</s>HARLOW: More from that interview in just a moment.</s>BERMAN: But first this morning, new information about the killer that unequivocally should have kept this man from owning a gun. Just no question about it. Domestic abuse so bad he once fractured his stepson's skull. And an admission from the Air Force that it dropped the ball reporting this man's previous conviction and everything it knew. We'll get the latest from the Pentagon in just a moment. But first, Dianne Gallagher on the scene in Southerland Springs, Texas. Dianne, what are you hearing from investigators?</s>DIANNE GALLAGHER, CNN CORRESPONDENT: So, John and Poppy, at this point they're not just trying to track down a motive, but also kind of put together a picture of who this shooter really was. Now, we are learning from them that at least their best lead at this point seems to be something stemming from this family dispute, an ongoing grudge with his wife's family that we're told that he just wasn't able to let go of and had become increasingly obsessed with over the past recent time here. Now, investigators let us know that he sent a threatening text message to his mother-in-law the morning of the shooting. We do not know the contents of that text message but it was described as threatening. She was not in the sanctuary, but his wife's grandmother was. She died in that shooting.
