On the morning of May 15, 2016, 33-year-old Salvador Ramirez was killed inside his Las Vegas home while his wife, Danielle Ramirez, and their children were present. The family had been hosting 34-year-old Mario Espinoza and Espinoza’s girlfriend until they could find their own apartment.

Two of the girls escaped, but a 10-year-old daughter could not get away. As that child watched, Salvador Ramirez was shot in the head. Danielle Ramirez fought the attacker and grabbed a knife, which caused Espinoza to flee; he was later apprehended by police. Espinoza, who had prior convictions including domestic assault and drug-related offenses, was charged with first-degree murder, attempted murder, and possession of a firearm by a prohibited person.

Are there witnesses or neighbors who saw activity at the house that night or who have information about Espinoza’s behavior in the days before the killing?
