The elementary school teacher who was fatally shot Saturday while showering in a stranger's home in Washington state may have believed he was in a friend's house, the New York Daily News reports. Prosecutor Michael Dorcy says Nathanial Rosa was staying at a friend's house nearby and had been out "drinking and celebrating." Dorcy says the house belonging to 59-year-old Bruce Fanning has the same floor plan as the house where Rosa was staying and the two homes "are almost identical." Dorcy says Rosa probably thought he was locked out of his friend's house, "but he's dead now so we can't confirm."
Fanning was charged with murder on Wednesday, the News Tribune reports. The charge was upgraded from second-degree to first-degree murder based on allegations of premeditation. According to the Kitsap Sun, Fanning found Rosa in the shower and left the house, which he uses for his business, before returning with a gun and allegedly shooting Rosa multiple times. Authorities say it's unclear why Fanning, whose property is adorned with signs warning "trespassers will be shot," didn't call 911 until after shooting Rosa. Fanning says he was afraid for his safety. Investigators are attempting to determine if Rosa was drunk at the time or suffering from hypothermia—his clothes were soaked. (Read more murder stories.)
