A 40 year old male was stabbed and killed on Sunday night in Las Vegas. Apparently the man, Justin Dale Boyer, got into a fight with a family member.

Boyer, a resident of St. John, North Dakota was staying with a family member in Las Vegas when neighbors found him screaming and bleeding outside their residence according to  The Review Journal, a newspaper in Vegas.

Boyer died of a sharp force injury and the death was ruled a homicide. The family member that Boyer was fighting with was not identified but detectives who interviewed the family member were told he acted in self-defense.

The Associated Press reports the family member was Boyer's brother.
