“There was not an inch on his body that not been bruised or scarred or injured” this child suffered everything from cigarette burns to being tied up with clothesline. A Texas woman convicted of the starvation and torture death of her girlfriend’s 9-year-old son a decade ago was executed Wednesday evening

Lisa Coleman, 38, received a lethal injection about an hour after the U.S. Supreme Court rejected a last-day appeal to spare her. She was pronounced dead at 6:24 p.m. CDT, 12 minutes after Texas Department of Criminal officials began administering a lethal dose of pentobarbital.

Coleman smiled and nodded to several friends and an aunt who watched through a window, thanking them and expressing her love. She also said she loved the other women on Texas’ death row and urged them to “keep their heads up.”

Coleman was condemned for the death of Davontae Williams, whose emaciated body was found in July 2004 at the North Texas apartment Coleman shared with his mother, Marcella Williams.

Paramedics who found him dead said they were shocked to learn his age. He weighed 36 pounds, about half that of a normal 9-year-old. A pediatrician later would testify that he had more than 250 distinct injuries, including burns from cigarettes or cigars and scars from ligatures, and that a lack of food made him stop growing.

“There was not an inch on his body that not been bruised or scarred or injured,” said Dixie Bersano, one of Coleman’s trial prosecutors. Coleman’s trial attorneys said the boy’s death at the apartment in Arlington was an accident. They said he may have had mental health issues that made him difficult to handle and Coleman and Williams didn’t know how to deal with him in a positive manner.

After a Tarrant County jury in 2006 convicted and sent Coleman to death row, Williams took a plea bargain and accepted a life prison sentence. Now 33, she’s not eligible for parole until 2044.
