On the morning of November 16, 2017, 41-year-old Nicole Nguyen was found in the garage of her Las Vegas home on College Green Street with a fatal gunshot wound to her torso. She was taken to St. Rose Dominican Hospital, San Martin campus, and pronounced dead about an hour after the shooting. Her estranged husband, 51-year-old John Fitzgerald Gonzalez, was at the scene; their 6-year-old son was inside the house and was unharmed.

Nguyen had filed for divorce seven weeks earlier and sought sole custody, describing Gonzalez in court filings as aggressive and threatening and citing safety concerns. Gonzalez gave shifting accounts to investigators about what happened, saying at one point that Nguyen produced a gun and it discharged during a struggle and later describing a sexual encounter in the garage during which a gun went off. Detectives called his explanations implausible and questioned why he would have brought two firearms and why a gun would be accessible during the alleged encounter. Gonzalez was arrested and charged with murder.

Anyone who knew Nicole, the family, or who has information about the events on November 16, 2017 is asked to come forward.
