Though the powers that be in Washoe County have not declared it as such, it appears the Sunday, April 5th, shooting of a man was done in self-defense. See the News4 story.
The deceased man was beating and strangling his girlfriend, but fled the scene before police arrived. He came back later looking for his girlfriend. On the return visit, the suspect had some sort of confrontation with the landlord, leading the landlord to be placed in "immediate danger." The landlord shot and killed the boyfriend.
According to the RGJ, "The landlord defended himself, shooting the suspect once, police said." This appears to be self-defense.
Side note: the RGJ published an article basically begging people to subscribe to keep them afloat. Uh, does the fact that your reporting sucks mean anything to you? Maybe if your investigated stuff, did more than regurgitate press releases and paraphrase government spokesholes people might read your stuff. Want to see an example of crap journalistic quality these days? Compare the RGJ article to the News4 Story.
