A Colorado woman is facing an attempted murder charge after authorities said she shot an alleged home intruder last weekend.

Police said Emily Strunk, 25, of Aurora, called 911 on Saturday after shooting a male intruder who allegedly broke into her apartment, FOX 31 Denver reported.

The initial investigation suggested the intruder, who had a previous relationship with Strunk, forced his way into the apartment and assaulted another man inside, identified as 27-year-old Kevin Wertin, police said.
