On the evening of June 19, 2016, 67-year-old Christine Ralston was walking her dog near the front office of The Suites on Boulder Highway in Las Vegas when a man approached from behind and punched her in the face. Her husband later told police the same man had previously banged on their door seeking sex; on an earlier occasion Ralston had defended herself with a bat and called police. Ralston was taken to Sunrise Hospital and Medical Center and was initially able to describe the attack, but she later fell unconscious and her condition worsened. She died on July 14, 2016; the Clark County coroner ruled her death a homicide.

Investigators identified a suspect, Alexander Duwarte, and say his phone records placed him near the scene. Two men also told police Duwarte had confessed to beating a woman who later died. Duwarte was arrested in August 2017 and booked on an open murder charge.
