Booth’s DNA was found on a 10-inch butcher knife recovered from McCarthy’s home. McCarthy was arrested after police found her name on a pawn shop receipt for the ring.
McCarthy blamed the crime on two drug dealers she identified only as “Kilo” and “J.C.”
“We could never turn up anything that would indicate they existed,” Parks said.
McCarthy was tried twice for Booth’s slaying, most recently in 2002. Her first conviction in 1998 was thrown out three years later by the Texas Court of Criminal Appeals, which ruled police violated her rights by using a statement she made to them after asking for a lawyer.
Prosecutors presented DNA and fingerprint evidence that tied McCarthy to similar slayings of two other women in Dallas in December 1988. Maggie Harding, 81, was beaten with a meat tenderizer and stabbed. Jettie Lucas, 85, was beaten with both sides of a claw hammer and stabbed. McCarthy was indicted but not tried for those slayings. She denied any involvement.
“When the jury saw the other two were equally gruesome, I think it sealed the deal for her,” Davis said.
McCarthy is a former wife of Aaron Michaels, founder of the New Black Panther Party, and he testified on her behalf. They had separated before Booth’s slaying.
McCarthy declined to speak with reporters as her execution date neared. She’s one of 10 women on death row in Texas but the only one with an execution date.
In 1998, Karla Faye Tucker, 38, became the first woman executed in Texas since the Civil War for a robbery in Houston where two people were killed with a pickax. Two years later, a 62-year-old great-grandmother, Betty Lou Beets, received lethal injection for the slaying of her fifth husband in northeast Texas to collect insurance and pension benefits. And in 2004, Frances Newton, 40, was executed for the 1987 slayings of her husband and two children in Houston.
At least eight male Texas prisoners have executions scheduled in the coming months.
