A North Dakota Man Decided to ‘Finish Off’ a Friend Injured in a Fight. Months Later, He Grew Paranoid and Also Killed His Pal’s Assailant.

A North Dakota man fatally struck a man with a metal iron and then decapitated another man with an ax in New Mexico in 2021. Now, he will spend decades behind bars in connection with those murders, according to authorities.

On the night of Jan. 29, 2021, the two victims, who were only identified as E.B. and P.S., reportedly got into a fight while they were drinking alcohol and using methamphetamine with 30-year-old Shilo Aaron Oldrock, a member of the Spirit Lake Sioux Tribe, according to the U.S. Attorney’s Office for the District of New Mexico.

During the dispute, P.S. sustained an injury and Oldrock didn’t help the man. Instead, Oldrock fatally struck him in the head with a metal iron as a way to “finish off” his friend, authorities said. Oldrock then burned the victim's remains in a barrel in an attempt to cover up the death.

The family of P.S. found his abandoned vehicle and then reported him missing to authorities. He was added to the List of Native Americans Verified as Missing Throughout New Mexico and the Navajo Nation by the FBI and his family continued to try to find him.

In mid-October 2021, Oldrock stabbed E.B. approximately 22 times and decapitated him with an ax because, officials said, he was “driven by paranoia from the killing of P.S. and the death of Oldrock’s grandmother." Oldrock then threw the E.B.'s head into a wood stove inside the victim’s home, as Front Page Detectives previously reported.

On the day of E.B.’s murder, Oldrock hitched a ride and asked the driver to take him to the flea market where his mother was working. The witness told police that Oldrock had a “black eye, cuts on his face, blood on his hands and blood on his clothes,” officials said.

During the drive, Oldrock reportedly admitted to the witness that he killed E.B., “chopped off” his head and then “threw his head in the wood stove.” Oldrock allegedly told the witness he was angry with E.B. because he believed he killed Oldrock’s uncle and “threw Oldrock’s mother to the ground.” He told the witness, “What comes around, goes around.”

Investigators recovered evidence connected to the crime, including a 4-foot ax and a “charred human head” from the wood stove.

Oldrock eventually confessed to law enforcement that he killed E.B. and P.S. In August 2023, he pleaded guilty to second-degree murder and voluntary manslaughter, authorities said.

On Nov. 28, a judge sentenced Oldrock to 35 years in prison in connection with the death of the two victims, officials said.

In a statement, U.S. Attorney Alexander Uballez said, "No amount of investigation, prosecution or years in prison will bring back a murdered loved one. But this team of local, tribal, and federal law enforcement partners will meet the case of each missing and murdered Indigenous person with urgency, transparency, and coordination."
