Texas man convicted of killing his mother 20 (UPI) -- A Texas man was found guilty of capital murder after running over his mother with his pickup as she was being lifted into an ambulance. Shaun Samuelson, 46, received an automatic sentence of life in prison without parole Wednesday after killing his 72-year-old mother, Virginia Samuelson, in Austin, Texas, last September. It took jurors only 30 minutes to reach their verdict, the Austin American-Statesman reported. Police said Samuelson, who hadn't had a job in years, was angry at his mother for not giving him money. When the two met so Virginia could give her son a government assistance check and $300 cash, they began to fight. During the altercation, Shaun Samuelson struck his mother at least 20 times in the head, officials said. She fled the area and went to a gas station across the street to call for help. As EMTs put her on a gurney and began loading her into the ambulance, Shaun Samuelson appeared from behind the wheel of his truck and crashed into his mother's gurney, killing her, police said. Jurors were shown a videotaped interview with detectives afterward, during which Samuelson said: "I was trying to hit my mom. I felt nothing but such great rage toward her at that point.
