[.....] Mr. Thomas, who confessed to the murders of his wife, their son and her daughter by another man, was convicted in 2005 and sentenced to death at age 21. While awaiting trial in 2004, he gouged out one of his eyes, and in 2008 on death row, he removed the other and ate it.

At least twice in the three weeks before the crime, Mr. Thomas had sought mental health treatment, babbling illogically and threatening to commit suicide. On two occasions, staff members at the medical facilities were so worried that his psychosis made him a threat to himself or others that they sought emergency detention warrants for him.

Despite talk of suicide and bizarre biblical delusions, he was not detained for treatment. Mr. Thomas later told the police that he was convinced that Ms. Boren was the wicked Jezebel from the Bible, that his own son was the Antichrist and that Leyha was involved in an evil conspiracy with them. He was on a mission from God, he said, to free their hearts of demons.

Hospitals do not have legal authority to detain people who voluntarily enter their facilities in search of mental health care but then decide to leave. [.....]
