A pair of 911 calls reveal the horror just before — and after — a former neo-Nazi allegedly fatally shot four people before turning a gun on himself in a Phoenix suburb.
Authorities believe Jason Todd "JT" Ready killed his girlfriend and three others, including a toddler, in a domestic dispute Wednesday at a Gilbert home.
Ready, 39, was the leader of a group of armed civilians that patrols Arizona's desert near the Mexican border for illegal immigrants and drug smugglers.
In one of the 911 calls, Ready's girlfriend is heard saying in a raised voice: "Oh my God. He's got a gun. No!" before the sounds of two shots.
In another call, a sobbing young woman tells a 911 dispatcher that "my mom and my niece and my sister are all on the floor. They're hurt pretty bad."
Asked by the dispatcher about the shooter, the woman said: "It's my mom's boyfriend, JT Ready."
Besides Ready, Gilbert police have identified the victims as Lisa Lynn Mederos, 47, Ready's girlfriend; Lisa's daughter Amber Mederos, 23; Amber's 15-month-old daughter, Lilly; and Amber's boyfriend Jim "Jambob" Hiott, 24.
Police released some of the 911 calls Monday.
Lisa Maderos' 19-year-old daughter, Brittany, identified herself to the dispatcher in a 911 call, saying she heard Ready and her mother "fighting and screaming and I was in my room under a bed... I come out and they're all on the floor and there's blood."
Gilbert police said they found two handguns and a shotgun at the home when they responded to the 911 calls.
A neighbor is heard on another 911 call saying he "heard about six shots" and saw the bodies of two men with "blood coming from their head" outside the home.
The neighbor added that he had just moved in next door to Ready, only knew his first name and thought he was a U.S. Border Patrol agent.
Authorities said Ready was a former member of the neo-Nazi National Socialist Movement and led a civilian border patrol group known as the U.S. Border Guard.
The FBI was already conducting a domestic terrorism investigation of Ready at the time of the shootings. The FBI's investigation dated to when Ready was a member of the neo-Nazi National Socialist Movement and continued into his participation with the border group, according to The Arizona Republic.
Search warrant affidavits obtained by the Republic show federal agents seized numerous computers and munitions from the Gilbert home where Ready lived and died in an apparent murder-suicide. The warrants imply weapons seized at the murder scene were stolen from the U.S. military. Focus on those weapons could trigger a larger federal investigation.
The murders gave the FBI access to Ready's documents and computers inside the home where he lived with Lisa Mederos and Brittany Mederos.
Documents connected to the search warrant show that the FBI agents seized two computer towers and two laptop computers, correspondence, cellphones, police and Nazi uniforms, white-supremacist propaganda and bank statements.
Agents seized two assault-style rifles and multiple rounds of ammunition. The reporting FBI agent focused on "approximately two dozen military ordnance/40 millimeter grenades" loaded with explosives, tear gas, buckshot and smoke.
