An 85 year-old Idaho woman’s memory about how exactly she shot an armed intruder dead with a .357 Magnum revolver last month is a little fuzzy but local prosecutors are pretty confident it was a case of justifiable homicide and are not investigating any further, Fox News reports.

That octogenarian Christine Jenneiahn herself took multiple 9mm rounds to her abdomen, leg, arm and chest when the fatally wounded 39 year-old Derek Condon returned then fire might explain the memory lapses, as Jenneiahn apparently recalled in pretty specific detail about how she was able to retrieve the hand cannon despite being partially cuffed to a chair while Condon looked for two safes.

“At one point while Condon was downstairs, Christine drug the chair she was handcuffed to into her bedroom, and retrieved her 357 magnum revolver from under her pillow,” wrote Bingham County prosecutor Ryan Jolley. “She then went into the living room and hid the revolver between the arm rest and cushion of a couch next to where she was seated and waited to see what Condon did next.”

Jenneiahn then decided it was “now or never” and things got real. With Condon having found out and herself gravely wounded, she then collapsed to the floor, laying there for 10 hours before her disabled son – who slept through the 2:00 AM gunfight – came across her and called 911. The moral of the story is sometimes old ladies are really tough and you should not ever fuck with them.
