An American citizen associated with the culprits behind the deadly Wieambilla shooting that claimed six lives – among them two officers from Queensland – has agreed to a watered-down plea deal.

Arizona-based Donald Day Jr will appear in court on 21 October after striking the plea deal with US prosecutors.

The individual with prior convictions, known online as “Geronimo’s Bones”, is expected to plead guilty to a sole charge of unlawfully possessing guns and bullets in a arrangement to be approved by the judiciary in the current month.

Connections to Aussie Gunmen

Investigators established direct links between the defendant and the Train couple through digital communications.

The Trains, along with Nathaniel Train, killed officers from Queensland Matthew Arnold and Rachel McCrow, and neighbour Alan Dare at a isolated location in Wieambilla, Queensland in 2022.

They were killed in a gun battle with police, following a protracted siege at the regional property.

American officials said the accused corresponded via social media with the Trains around the time of the fatal attack.

Day described Queensland officers as “malignant, malformed and malevolent”, and said they should be shown “absolutely no quarter”, informing the Trains he wanted to be at Wieambilla in person.

Court documents detailed how Gareth and Stacey Train had posted an end-times recording on YouTube after the shootings, stating police “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,” they expressed.

Weapons Stockpile and Legal Proceedings

Legal records show Day stockpiled a collection of nine high-powered firearms and hundreds of rounds of ammunition at a country estate in Heber, Arizona, that was equipped with a gun range, weapons room and sniper’s nest.

“The guns and ammo were stored in the trailer I occupied with S.S., within a space we named the 'gun room',” he admitted in the agreement submitted in the legal system.

He said he frequently used both the gun room and the firearms, and also trained others on how to operate the firearms correctly.

The plea deal will result in charges dropped that pertain to the alleged making of threats to public figures and FBI agents.

Based on legal files, Day had been prohibited from owning weapons and firearms because of his history of violent crimes.

Day, who has served two years in custody, could receive a maximum penalty of up to 15 years in prison or a fine of US$250,000 (A$381,500), but the agreement specifies he will be sentenced under the low end of the sentencing guidelines.
