LAS VEGAS (KLAS) — A man who called police Friday to report that he fatally stabbed another man in self-defense at their east valley apartment complex is facing a charge of open murder, Metro police said.

Brandon Alexander, 64, who lived in the complex on the 4300 block of Boulder Highway and was a neighbor of the victim, according to police, was jailed at the Clark County Detention Center. He was due in court Sunday on a charge of open murder with a deadly weapon.

Lt. Jason Johansson of the Las Vegas Metropolitan Police Department’s homicide section said the stabbing at the complex south of South Lamb Boulevard was reported in a 911 call at 7:19 p.m. Friday.

When officers got to the complex, they found the man who made the call, Alexander, and took him into custody, Johansson said. They also found the other man with stab wounds, and medical personnel pronounced him dead at the scene, he said.

Johansson said Friday night the investigation was in its preliminary stages and he did not know if the victim was armed. A news release from police Sunday did not add clarity.

The two men, both white and in their 60s, were in the victim’s apartment when the stabbing happened, he said.

“What we’re being told is that they might have had a relationship in the apartment complex of not liking each other,” he said.

The open murder charge means a conviction can be returned on any of the state’s classifications of murder, ranging from first degree to manslaughter.

Police said the victim’s identity would be released pending an examination by the Clark County Coroner’s Office.
