Authorities have charged a 73-year-old man with murder in a recent shooting that killed a man and wounded a woman in a rundown duplex in suburban Reno, Nevada.

The defendant, Wayne Burgarello, acknowledges the Feb. 13 shooting at a property he owns in Sparks but says he was acting in self-defense under Nevada's "stand your ground" law.

Activists hailed prosecutors Wednesday. Debbie Peckham, mother of 34-year-old Cody Devine, says her son was "in the wrong place at the wrong time" when he was killed. She says he was unarmed and wasn't a threat.

Burgarello was arrested and charged Tuesday. He is being held in county jail without bail and doesn't yet have a lawyer.

More than 30 states have "stand your ground" laws that allow deadly force against imminent threats.
