Pulitzer Prize-winning author Cormac McCarthy's ex-wife was arrested after allegedly threatening her boyfriend with a gun that she pulled out of a very unlikely place.

McCarthy's boyfriend was able to wrestle the weapon away from her, threw it in the toilet and then later moved the gun to the trash outside. The Albuquerque Journal reported that McCarthy was wearing lingerie at the time of the assault.

McCarthy was charged with aggravated assault on a household member.
