On January 30, 2016, 40-year-old Denise Gray was found wounded at the doorway of her Las Vegas townhouse on Terrazzo Avenue after calls about a woman crying out for help. Neighbors reported hearing her on the floor yelling for help; police arrived around 2:40 a.m. and found Gray with a gunshot wound. She was taken to University Medical Center, where she later died.

Initial reports led investigators to treat the incident as a homicide and it was counted among the city’s early-year violent deaths, but detectives were unable to establish a motive at the time. In March 2016 the Clark County coroner ruled the death an accident, identifying the cause as a gunshot wound to her left thigh. After the coroner’s ruling, no arrests or suspects were announced and the case was not classified as a homicide.

What details about that night or about Denise’s movements before 2:40 a.m. might help clarify how a gunshot wound to the thigh was fatal?
