A Las Vegas man has been arrested and charged with open murder after allegedly shooting and killing his roommate, Anton Watson, following a drunken accusation that Watson had slept with Thompson's girlfriend, Allayah Muhammad. Police say the incident occurred at the apartment the three shared, with Muhammad witnessing the aftermath of the shooting.

Why it matters

This tragic incident highlights the dangers of domestic disputes escalating to violence, especially when alcohol is involved. It also raises questions about the role of mental health, jealousy, and trust in intimate relationships. The case will likely prompt discussions around gun violence, domestic abuse, and the need for better conflict resolution resources in the Las Vegas community.

The details

According to police, on the morning of February 18th, 2026, Thompson returned home after drinking heavily and accused Watson, his roommate of one month, of having an affair with his girlfriend Muhammad. An argument ensued, and Thompson allegedly shot and killed Watson in the apartment hallway. Muhammad told police she did not believe Watson did anything to provoke Thompson in a way that would justify the shooting, and there was no physical altercation beforehand. Thompson then fled the scene but was later arrested about 12 miles away. Police found two 9mm cartridges in Thompson's pockets that matched the casings found at the crime scene.

  • On February 18, 2026, at around 10:15 a.m., police received a call reporting a man had been shot and was lying in the apartment complex parking lot.
  • Thompson was arrested about a dozen miles from the scene shortly after the shooting.
