US Man Linked to Aussie Shooters Strikes Plea Bargain with Federal Attorneys

A US man linked with the perpetrators behind the deadly Wieambilla attack that took six lives – including two Queensland police officers – has agreed to a watered-down plea deal.

Resident of Arizona Donald Day Jr will appear in court on 21 October after striking the bargain with American authorities.

The individual with prior convictions, known online as “Geronimo's Bones”, is anticipated to admit guilt to a single offense of unlawfully possessing guns and bullets in a deal to be approved by the court in the current month.

Connections to Aussie Gunmen

Authorities confirmed clear connections between Day and the Train couple through digital communications.

This couple, along with Gareth’s brother Nathaniel, murdered Queensland police officers Matthew Arnold and Rachel McCrow, and neighbor Alan Dare at a remote property in Wieambilla in 2022.

The Trains were killed in a final shootout with police, following a protracted siege at the rural site.

US prosecutors stated Day corresponded via social media with the perpetrators around the time of the fatal attack.

Day referred to Queensland officers as “evil, corrupt, and wicked”, and said they should be shown “no mercy whatsoever”, informing the Trains he wanted to be at Wieambilla physically.

Legal filings outlined how the couple had posted an end-times video on the video platform 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,” the Trains said.

Weapons Stockpile and Court Case

Legal records show Day accumulated a collection of nine high-powered firearms and hundreds of rounds of ammo at a country estate in Heber, Arizona, that was equipped with a shooting range, gun 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',” Day said in the agreement filed in the legal system.

He said he regularly accessed both the gun room and the firearms, and also trained others on how to use the guns correctly.

The plea deal will result in dismissed counts that pertain to the alleged issuing threats to officials and federal agents.

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

Day, who has completed two years in detention, could receive a highest sentence of up to 15 years imprisonment in prison or a penalty of US$250,000 (A$381,500), but the agreement stipulates he will be judged under the low end of the sentencing guidelines.
