Kimberley McCarthy, a cocaine-addicted home health care worker was convicted of robbing and killing a 71-year-old Dallas woman, Dorothy Booth.
As a few dozen protesters gathered outside the prison in Huntsville, McCarthy, 52, was put to death by lethal injection yesterday, according to the Texas Department of Criminal Justice, making her one of a small number of women to have been executed.
McCarthy was the fourth woman executed since Texas adopted the practice of lethal injection in 1982.
McCarthy claimed Dallas prosecutors exhibited racial bias in eliminating three African-Americans from the jury panel. Only one juror in McCarthy's trial was black. McCarthy was African-American.

McCarthy was convicted of fatally stabbing her neighbour, retired university professor Dorothy Booth, in July 1997.
Prosecutors argued the killing was prompted by a robbery, in which McCarthy severed her victim's finger in order to steal a ring. The ring and other items taken from the home then were converted to cash for drug purchases.
Additionally, she had convictions for forgery, theft of services and prostitution.
McCarthy's attorney, Maurie Levin of the University of Texas Capital Punishment Clinic, said the conviction came as a result of "discrimination and racial bias and inadequate counsel appointed by the state.
Many US states have imposed a moratorium on the death penalty, with few executions carried out and convicts on death row.
A total of 1,336 people have been executed across the United States since the Supreme Court lifted a moratorium on the death penalty in 1976 and over a third of the executions were carried out in Texas.
