APRIL 2 UPDATE: The Clark County Coroner has identified the three people killed in the incident from March 27.
15-year-old Kevin Figueroa and 17-year-old Alex Figueroa were both shot multiple times and their deaths were ruled homicides.
45-year-old Alejandro Figueroa died of a self inflicted gunshot to the head, ruled a suicide.
A Las Vegas man is believed to have shot and killed his two teenage sons before shooting and killing himself Friday night.
The incident took place in the 3900 block of Chasing Heart Way, near Nellis Boulevard and Craig Road, according to Las Vegas Metropolitan Police Homicide Lt. Ray Spencer.
Spencer said a neighbor called police to report gunshots around 10:30 p.m. and the dispatcher could hear gunshots during the call.
He said when officers arrived, a teenage girl climbed out of one of the home's windows and told them that her two brothers were still inside.
"Obviously, it is a life or death situation," Spencer said. "We knew there was gunfire inside the house."
Spencer said SWAT was immediately activated and made an entry for hostage rescue as soon as they got on scene. However, both boys and the father were dead when they entered and had likely been dead before they arrived.
Police later identified the father as 45-year-old Alejandro Figueroa. He died of a self-inflicted gunshot wound.
Investigators reported that Figueroa had been drinking and handling a gun. One of the teens then called the police and Figueroa became upset and shot the two teens before turning the gun on himself.
Spencer said the girl was not injured, and her mother was not at home at the time of the shooting.
Spencer also mentioned that during the current state-wide coronavirus lockdown, there could be a lot of stress on families.
He urged anyone who's feeling stressed to call therapists at the Family Justice Center or by calling 2-1-1.
