She sent her 72-year-old son, 92, to Arizona to the grave because he wanted to send her to a nursing home.
Anna May Blessing was arrested Monday at a Phoenix suburb she was sharing with her son. She was taken into custody and the bail for her temporary release with restrictive conditions was set at $ 500.000, judges clarified.
She did not plead not guilty or be guilty in connection with the briefing. It is not clear if he has a lawyer.
Blessing confessed to the police officers who arrested her that she hid two pistols in the pockets of her robe and went to confront her son in his bedroom. He suffered multiple injuries, the sheriff's office in Marikopa County said in a statement.
The suspect also said that then she tried to point the guns at her son's 57-year-old girlfriend, but she managed to take her weapons after a fight, the sheriff's office added.
Blessing was sitting in a reclining seat in her bedroom when she was arrested. He refused to leave the house.
She told police she confronted her son because he intended to send her to a nursing home because, he told her, it was difficult to live with her.
Blessing told police she had to be "put to sleep" for her act and that she wanted to commit suicide.
The 92-year-old said she had bought one of the pistols and that the other had been given to her by her late husband, but added that the two weapons had been in use since the 1970s.
Police said officers had visited the house again, following a complaint they received about a dispute between the elderly woman and her son.
