Detective Vega summarized interviews conducted by investigators with the victim, family and a neighbor. He told the panel that Yvonne Alvarado described a history of domestic violence, said Fabian Leon grabbed her, kicked her and threatened "one of us is going to die today," and that he at one point threatened to harm puppies in the house.
Vega said Alvarado told investigators Leon would "pretend that he had a firearm and walk outside so police would shoot and kill him." The detective also summarized an interview with Alvarado's adult son, who said he did not personally observe the assault that morning but had seen prior violent incidents and heard officers give commands. A neighbor, identified as Nicholas Inguez, said he heard ongoing police commands, saw Alvarado run out followed by a male, and believed the male had an object in his hand that may have been a knife.
