AKIPRESS.COM - 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, reports AP.

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 became the ninth convicted killer and second woman to receive lethal injection in Texas this year. Nationally, she's the 15th woman executed since the Supreme Court in 1976 allowed the death penalty to resume. During that same time, nearly 1,400 men have been put to death.

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."

"I'm all right," she said. "Tell them I finished strong. ... God is good."

She mouthed an audible kiss, laughed and nodded to her witnesses in the seconds before the lethal drug took effect.
