A Washington state man was arrested on suspicion of second-degree murder after police said he shot and killed an intruder who was showering inside his house.

Bruce Fanning, 59, of Mason County, discovered a stranger showering in one of the two residencies that he owns Saturday at around 8 a.m., Sheriff’s Lt. Travis Adams said. Adams added that Fanning runs a business out of a second property.

Fanning told investigators that he ran from the scene, grabbed a gun and then returned and shot the intruder, court documents showed. Fanning told police he thought the stranger was drunk and claimed he became afraid when the stranger made threats toward him, Q13 Fox reported.

Fanning fired four shots through the shower curtain, killing the intruder, the New York Times reported. Fanning called authorities after the shooting.

The victim was identified as Nathaniel Joseph Rosa, 31, of Bothell. Rosa had worked at Woodmor Elementary School in Bothell and was described as a “compassionate educator,” according to Q13 Fox.

Police said there was no indication that Fanning was threatened by Rosa and that the facts did not support Fanning’s right to self-defense. According to Washington state law, “no person in the state shall be placed in legal jeopardy of any kind whatsoever for protecting by any reasonable means necessary, himself or herself, his or her family, or his or her real or personal property.”

Authorities were still trying to determine why Rosa apparently broke in.

Fanning’s bail was set at $250,000.
