Diana Cristina Rios, 24, was found dead in a vacant Las Vegas apartment undergoing renovations at 3947 Silver Dollar Avenue on December 26, 2016. A contractor discovered her unresponsive body in a bedroom around 4:30 p.m.; the Clark County coroner later determined she had been strangled. At the time she was a mother of two and about thirteen weeks pregnant with a third child.

Investigators focused on Diana’s former boyfriend and the father of her children, 24-year-old Salvador Gonzalez, after a contractor working in the hallway saw a nervous man who asked for a cigarette and then left shortly before the body was found. A 7-Eleven cup near the body and surveillance footage from a nearby 7-Eleven showed Diana and Gonzalez together shortly before the killing. Reports describe a history of domestic violence between the couple, including a prior threat by Gonzalez to kill her; he denied knowing her at one point during questioning.

Was anyone in the neighborhood or who worked on the renovation aware of the couple’s disputes or of the man seen in the hallway that afternoon?
