A domestic dispute in North Las Vegas on July 13, 2015 ended with a fatal shooting. Tsai F. Mattox, 70, was shot in the chest inside her home on the 2300 block of Plumeria Avenue, near Losee and Lone Mountain roads. She was taken to University Medical Center but died from a single gunshot wound.

Her husband, 78-year-old Arthur Mattox, called 911 and admitted to shooting her. He was taken into custody by North Las Vegas police and booked into the Clark County Detention Center on a charge of open murder; a judge set bail at $1 million.
