A US man associated with the culprits behind the fatal Wieambilla, Australia attack that claimed six lives – among them two officers from Queensland – has accepted a watered-down plea agreement.
Resident of Arizona Donald Day Jr will face court on October 21 after finalizing the plea deal with American authorities.
The convicted felon, referred to online as “Geronimo's Bones”, is anticipated to plead guilty to a sole charge of unlawfully possessing firearms and ammunition in a deal to be sanctioned by the judiciary in the current month.
Authorities established direct links between Day and Gareth and Stacey Train through online posts.
The Trains, along with Nathaniel Train, killed Queensland police officers Matthew Arnold and Rachel McCrow, and neighbour Alan Dare at a isolated location in Wieambilla, Queensland in 2022.
The Trains were killed in a gun battle with police, following a protracted siege at the regional property.
American officials said the accused communicated via social media with the perpetrators around the time of the fatal attack.
Day described Queensland police as “malignant, malformed and malevolent”, and declared they should be shown “absolutely no quarter”, informing them he wanted to be at Wieambilla physically.
Legal filings detailed how Gareth and Stacey Train had uploaded an end-times video on YouTube after the shootings, saying authorities “attempted to kill us, and we retaliated”.
“If you don’t defend yourself against these devils and demons, you’re a coward … We will meet you at home, Don. With love,” the Trains expressed.
Legal records reveal the defendant stockpiled a collection of multiple powerful guns and hundreds of rounds of ammunition at a country estate in Heber, Arizona, that was outfitted with a shooting range, gun room and sniper hide.
“The firearms and ammunition were kept in the mobile home I shared with S.S., in a room we called the ‘gun room’,” Day said in the plea deal submitted in the legal system.
He said he regularly accessed both the weapons storage and the weapons, and also instructed individuals on how to operate the firearms correctly.
The bargain will result in charges dropped that pertain to the alleged issuing threats to public figures and FBI agents.
According to legal files, Day had been banned from owning guns and arms because of his history of violent crimes.
Day, who has served 24 months in detention, faces a highest sentence of up to 15 years imprisonment in prison or a fine of US$250,000 (A$381,500), but the plea deal stipulates he will be sentenced under the minimum range of the legal sentencing standards.
