A Texas woman was executed Wednesday evening for starving her girlfriend’s 9-year-old son to death a decade ago. Lisa Coleman received a lethal injection after the U.S. Supreme Court rejected her final appeal for a stay of execution.

The 38-year-old, who was pronounced dead 12 minutes after officials from the Texas Department of Criminal Justice administered the lethal dose of the sedative, is the fifteenth woman to be executed in the U.S. since the Supreme Court resumed the death penalty in 1976. Nearly 1,400 men have been executed in the same period. Coleman was sentenced to death after she was found guilty of killing Davontae Williams, her partner Marcella Williams’ son in July 2004. 

"I'm all right," Coleman reportedly said, as her relatives watched her through a glass window. "Tell them I finished strong. ... God is good."

The body was found in a North Texas apartment shared by Coleman and Marcella. Health care professionals who examined the body of the boy revealed that Davontae’s weight was nearly half that of a normal 9-year-old boy, The Associated Press reported. They also reportedly testified that the boy had more than 250 injuries on his body. These injuries were reportedly caused due to burns from cigarettes and several scars from binding.

"There was not an inch on his body that not been bruised or scarred or injured," Dixie Bersano, one of Coleman's trial prosecutors, said, according to AP.

Coleman is also reportedly the ninth convicted killer and second woman to receive a lethal injection in Texas this year.

Davontae’s mother, Marcella, was also reportedly arrested in connection with the murder and took a plea bargain and was given a life sentence after Coleman was convicted and put on death row by a Tarrant County jury in 2006. The 33-year-old Marcella is reportedly not eligible for parole until 2044.

"She (Marcella) was as culpable in the death of Davontae Williams as my client, and that is what seems unfair," Fred Cummings, Coleman's original trial attorney, said in a recent interview, according to USA Today.
