Texas executes mentally handicapped man despite UN protest

Texas executed a convict Wednesday, despite proof of a mental disorder developed in his childhood, prison authorities from the southern US state said.

Yokamon Hearn, a 34-year-old African American,

was sentenced to death at age 19 for killing a white man in a carjacking. Hearn was pronounced dead by lethal injection on Thursday. For the first times, Texas executioners administered one single injection of pentobarbital.

Several states are using the new injection, after one of the three traditional injections used in executions had run out of stock.

"I would like to tell my family that I love (you), and I wish," Hearn said in his last statement, trailing off before a final, "Well. I'm ready." On death row for 14 years, Hearn was diagnosed with mental disorders related to fetal alcohol syndrome, caused by his mother's alcohol abuse during pregnancy, and severe neglect as child. Hearn had suicidal thoughts at age 10 and suffered brain damage, according to Texas-based criminal justice system advocacy group StandDown.
