GILBERT, Ariz. -- Investigators have shed more light on the background of a neo-Nazi who is accused of murdering four people, then killing himself, in Gilbert on Wednesday afternoon.
It started as a domestic violence call of some sort, officers expedited when they heard that shots had been fired. Police believe someone in the house called 911 moments before the trigger was pulled.
When officers arrived, they found four adults dead, along with a 15-month-old girl, who later passed away at the hospital.
Among the dead, was J.T. Ready, who investigators believe opened fire on the other four, then turned a handgun on himself.
The FBI's Joint Terrorism Task Force served a search warrant at the house overnight, recovering a stockpile of military-grade munitions, including several grenades and hazardous chemicals.
There was no launcher, which is required to detonate the grenades, so the FBI said there was not an immediate threat to the public. The U.S. Air Force has taken possession of the grenades.
Ready founded a border group, which looked for illegal immigrants. He's a former U.S. Marine, who was given a bad conduct discharge in 1996 for going absent without leave, larceny, conspiracy, and assault.
Last year, he launched an exploratory committee to decide whether to run for Pinal County Sheriff. He has also run for political office in Mesa.
Ready has been the subject of several previous local law enforcement investigations, including domestic violence, burglary, and disorderly conduct. In some of the cases, he was the victim, in others, the suspect.
The shootings on Wednesday resulted in the biggest homicide investigation in Gilbert's history.
