Rosa Monarrez, a 59-year-old Hispanic woman, was found dead in her Las Vegas home on the evening of January 1, 2012. Her brother discovered the body in the residence on the 1000 block of Bracken Avenue near South Maryland Parkway and East Oakey Boulevard. The Clark County coroner determined the cause of death was a gunshot wound to the neck.

Investigators focused on Rosa’s 29-year-old nephew, David Monarrez, who lived in the house with her and other family members. The two reportedly had constant conflict, often about money. David, who is deaf and diagnosed with schizophrenia, was taken into custody in the early hours of January 2 when he returned to the home. Officers found a black and gray nylon bag containing a 9 mm handgun with blood and hair on it; David initially denied ownership but later described the bag’s contents and admitted to shooting his aunt, saying he bought the gun for $500. He was booked on a murder with a deadly weapon charge and held without bail.

Did anyone in the neighborhood or family know of escalating disputes between Rosa and her nephew that could shed light on what happened?
