52-year-old Kimberly McCarthy will be the 500th inmate executed in Texas.

The State of Texas will execute the woman on account of an alleged murder that might have taken place in 1997, where the former occupational therapist would have killed her 71-year-old neighbor in a robbery.

The Texas authorities claimed that the soon-to-be-executed woman had previously entered the 71-year-old retired professor's home, stabbed the old professor multiple times, then took her vehicle and credit cards.

Texas has carried out the most executions since 1976 when the death penalty was reinstated by the Supreme Court. This Texas woman's execution will mark the 500th time.

Oklahoma, Mississippi, Arizona and Texas executed 75% of all U.S. death penalty inmates in 2012.

Texas might soon execute the woman if the case is not overturned. McCarthy could have been the victim of racial discrimination due to the selection of her jury. She was given a jury with only one African American member. The Texas woman to be executed is also African American.

The issues in McCarthy's case "reflect problems that are central to the administration of the death penalty as a whole," Levin said. "For this to be the emblem of Texas' 500th execution is something all Texans should be ashamed of."
