Police officers who responded to a report of a domestic disturbance found an unresponsive female with an apparent head wound.
According to Stanley's arrest report, the argument happened after Stanley returned home to find his girlfriend drinking. He described her to police as an alcoholic. Stanley eventually left for a few hours before returning and the argument continuing.
Stanley told police his girlfriend then went to the convenience store to buy more champagne but she was slow to return. Stanley went searching for her around convenience stores and apartment complexes she was known to frequent. He eventually found her in the complex.
According to Stanley, his girlfriend was there with another woman whose hair she was going to be dyeing. He was told to go back their apartment.
When his girlfriend returned to their apartment, another argument began and Stanley told police his girlfriend threw a drink at him. She left toward the east stairwell with Stanley following. Stanley told police he only intended to grab her and bring her back into the apartment when she fell down the stairs as she was pushing Stanley's arm away.
After she fell, she was transported to UMC Trauma where she later died. The Clark County coroner identified her as 24-year-old Kimberly Johnson of Las Vegas. She died of blunt force trauma to the head.
