Anna Mae Blessing told authorities she had been contemplating her 72-year-old son's intention to send her away for several days because she had "become hard to live with" before she confronted him, according to a press release by the Maricopa County Sheriff's Office.
Anna Mae Blessing fatally shot her son Monday morning at their home in Fountain Hills, the Maricopa County Sheriff's Office said in a press release.
She fired one of the pistols multiple times, striking and killing her son before pointing the gun at his girlfriend, who wrestled away the firearm and threw it into a corner of the room, court records show.
When authorities later questioned the suspects, Blessing said her son wanted to her to leave their shared apartment because she "had become hard to live with".
Deputies rushed to the home for "unknown trouble" and found her son dead in his bedroom and the woman believed responsible for the shooting relaxing in a recliner chair.
She pulled out a second pistol, which she told police her late husband had given to her in the 1970s, the BBC report said.
Despite her age, Blessing is some way off becoming the oldest murderer in American history.
Blessing then turned the gun on his girlfriend and the two struggled over the weapon, police said.
Sheriff's deputies arrested Anna Mae Blessing in Fountain Hills, Arizona, on Monday. Blessing reportedly also claimed that she meant to kill herself after, but didn't have any other weapons.
Blessing was in a wheelchair at her initial court appearance Tuesday where her bond was set at $500,000 and a lawyer was being appointed to represent her.
"It is always concerning when domestic issues escalate to violence or tragic outcomes", Penzone told KSAZ-TV. 'They are often isolated and neither predictable nor preventable'.
When Blessing was asked what she thinks should happen to her, she replied she should be "put to sleep" as a result of her actions. The case resumes on July 13.
