AUSTIN MAN pulls a gun on his pregnant girlfriend over baby shower money, then shoots their roommate in the head. It started Tuesday evening at an apartment complex on Menchaca Rd. Christopher Foy, 24, had doubts the baby was his, and he wanted back the money he'd given her for the shower. He was outside the apartment yelling at her when he pulled a handgun from his waistband, waved it around, pointed it at her, and started threatening to shoot people. Their roommate, Miguel Guevara, wasn't home. When a relative told him Foy had pulled a gun, he drove back to confront him. He parked right out front, got out, and started walking toward Foy. Foy saw him coming. He pulled the gun and fired once from a few feet away. Then he got in his white Ford Fusion and drove off. Guevara went down on the sidewalk outside the front door and died. Foy was booked into Travis County Jail on a murder charge. Guevara would have turned 35 next week.
