Despite years of treatment, a 91-year-old former Hurst resident accused of killing her neighbor in 2003 has been found incompetent to stand trial for murder for the 15th time, according to Tarrant County court records.
Kristal Locke, 91, was found incompetent Monday in Criminal District Court No. 297 based on the recommendation of the medical staff at the San Antonio State Hospital, where she has been the last few years.
Dr. Matthew Hopkins wrote that there had been no significant changes in Locke’s clinical presentation, saying she remains “paranoid, delusional and not competent to stand trial.”
Locke has been found incompetent 15 times since her arrest in 2003. She remains the oldest person under indictment in Tarrant County in a pending murder case.
Never miss a local story.
Locke is accused of fatally shooting her neighbor, Linda Porter, on April 11, 2003, at a condominium complex in the 600 block of Bellaire Drive in Hurst. According to Hurst police, Locke, then 78, believed that Porter, 55, was trying to steal a man from her.
Porter didn’t know the man, but Locke was fixated on him and had been harassing him for more than 20 years.
Locke still believes that shooting Porter was an act of self-defense, according to an April report by psychiatrist Vicky L. Litton at the San Antonio hospital.
Locke told Litton that she was concerned that a man wearing a hat was trying to marry her.
When asked why she was at the hospital, Locke replied, “I don’t want to remember why I’m here,” according to the report.
Hopkins, who is medical director of geriatric services at the San Antonio hospital also noted that Locke remained mentally ill, and that she was likely to cause serious harm to others.
Last year after a court-ordered evaluation, a psychiatrist wrote that it “seems unlikely she will ever be able to have her competency restored.”
