A 60-year-old man in Las Vegas, Nevada is accused of fatally shooting his ex-girlfriend Krystal Graham, 42, and then setting their shared home on fire. Police say William Hall had smoked meth earlier in the day and became enraged, believing his roommates were spying on him and trying to ruin his life. Hall allegedly shot Graham twice in a motor home outside the house before being arrested at the scene.

Why it matters

This tragic incident highlights the dangers of domestic violence, substance abuse, and mental health issues. It also raises questions about the availability of support services and intervention programs to prevent such escalating situations from turning deadly.

The details

According to the police report, Hall lived with Graham, her husband David MacArthur, their two children, Graham's brother Chance Graham, his wife Linnea Hayden, and Graham's mother Peggy Graham. Less than two weeks before the incident, Graham had accused Hall of molesting their adult daughter, leading her to tell him he needed to move out within three days. On the day of the shooting, Hall said he smoked meth around 3:30 pm to "calm himself" before waking up angry a few hours later. He then set his bedroom on fire, armed himself, and waited for Graham and MacArthur to exit the burning home, intending to shoot MacArthur. When Graham came out alone, Hall shot her twice, killing her.

  • On February 20, 2026, police responded to reports of a shooting and house fire on Gabriel Drive in Las Vegas.
  • On February 25, 2026, William Hall appeared in court for his arraignment.
