A Texas jury on Thursday took less than an hour to convict Chante Mallard of murdering a homeless man she struck with her car and left dangling from the shattered windshield. At the sentencing hearing after the verdict, Mallard, 27, apologized and accepted responsibility for her actions. She did not testify during the trial. Mallard, a nurse's aide, said a half-tablet of ecstasy taken hours before the crash affected her judgment. "I was scared and didn't know what to do," she said. "I couldn't think and do the right thing. "I have ruined the lives of other people. I have put people through pain. I am so sorry," she said. Mallard said she doesn't deserve probation. "I do feel like I need to be punished." In closing statements Thursday, prosecutor Christy Jack said Mallard was guilty of murder because she failed to stop and get medical help after hitting Gregory Biggs, 37, on a Fort Worth freeway in the early hours of Oct. 26, 2001. Had Mallard sought aid, Biggs could have survived his injuries, Jack said. Instead, Mallard left him alone in her garage, "turned off the lights, shut the door and left him to die. It was Greg Biggs' darkest night." Defense attorney Jeff Kearney argued that the crash was an accident and that Mallard was too impaired by drugs to act responsibly. He also said prosecution witnesses were not credible. The prosecution's blood-splatter expert had scant credentials, Kearney said. Mallard's confession was taken by a police veteran who interviewed a frightened Mallard without witnesses. Prosecution testimony was questionable, and "we're not at a point where we start guessing people into the penitentiary," Kearney said. Mallard's testimony at the sentencing hearing Thursday mostly mirrored the story that her friend Titilesee "T" Fry told the jury during the trial. Fry got immunity from prosecution in return for testimony against Mallard. On the night of the crash, Mallard said she and Fry partied for most of the night, sharing a tablet of ecstasy, smoking marijuana and drinking at Joe's Big Bamboo Club. Mallard said the ecstasy affected her more profoundly than it had the one time she had previously taken the drug. "I was real loose. I had no control over myself," she said. After the club closed, Fry got behind the steering wheel of Mallard's gold 1997 Chevy Cavalier while Mallard sat in the passenger's seat. Fry drove to her own house and went inside. Mallard moved to the driver's side and headed toward the freeway. As she rounded a curve that connected one freeway to another, "I hit Mr. Biggs," said Mallard, crying. She said she didn't see him walking along the freeway. "When I hit him, there was a loud noise and all this glass started flying in the car. There was a lot of wind." As Biggs flew through the windshield, "I never saw his face. He was on the floor, underneath the dashboard on the passenger side. One leg was, like, somewhat out of the front glass, from the crease of the knee down," Mallard said. She said she was screaming and crying. "I didn't know what to think. I was scared and asking God to tell me what to do." Mallard exited the freeway, stopped and continued to wail, she said. At some point, she walked around to the passenger side of the car. "I touched his leg for half a second and I started yelling and screaming again," she said. Mallard said she doesn't remember getting back into the car, but she found herself driving again when she heard Biggs moan. "It was the first time I heard him," she said. As she drove toward her home, it never occurred to her to stop at a nearby fire station or call the police on a pay phone at a convenience store, Mallard said. Mallard said she stumbled into the house and called Fry. She didn't call her parents or her brother, who is a firefighter and an emergency medical technician. "They would have been so ashamed of me," she said. "I was scared to tell my family." Fry drove to Mallard's house and took a look in the garage while Mallard continued to cry in the living room. The pair decided to go back to Fry's house, Mallard said. There, Mallard called a former boyfriend, Clete Jackson. "I told him I had an accident and hurt someone." Jackson testified during the trial that he and a friend pulled Biggs out of the windshield, wrapped him in a blanket and dumped him in a nearby park. Jackson and his friend pleaded guilty to tampering with evidence and were sentenced to prison. The sentencing phase continues today. Mallard faces up to life in prison.
