New Tampa Man Admits To Murdering His Roommates & To Neo-Nazi Ties

Devon Arthurs walked into the Green Planet Smoke Shop in New Tampa at around 5:30 p.m. on May 19, held three hostages and then surrendered to police before revealing that he had shot his two roommates back in the apartment they shared at the Hamptons in Tampa Palms.

Things got stranger from that point on.

According to a Tampa Police Department (TPD) report, the 18-year-old Arthurs ended up telling officers he fatally shot Jeremy Himmelman, 22, and Andrew Oneschuk, 18, because they disrespected his recent conversion to Islam. Arthurs claimed the three men previously shared neo-Nazi beliefs (a claim denied by the family of the two victims in a Tampa Bay Times story).

Stranger still, when police took Arthurs back to the apartment, a fourth roommate, Brandon Russell, was outside the door crying.

Russell, a Florida National Guardsman, was the one who leased the apartment, according to a federal complaint filed on May 20.

Police found Himmelman and Oneschuk dead inside, with gunshot wounds to the upper body and head. After being read his Miranda rights, Arthurs voluntarily agreed to speak with law enforcement officials and confessed to the shootings, providing specific information about the weapon he used and the exact location of the shot placement on each victim. Arthurs told authorities that Russell had nothing to do with the shootings, but that he had participated in online neo-Nazi chatrooms “where he threatened to kill people and bomb infrastructure.”

TPD obtained a search warrant for the residence, and discovered a cooler in the garage (beneath the apartment) “containing a white, cake-like substance that two FBI and TPD bomb squad technicians immediately recognized …as HMTD (an explosive also known as hexamethylene triperoxied diamine).”

Other explosive precursors were found in the garage, including one in a package addressed to Russell. Electric matches and empty 5.56-caliber ammunition casings with fuses that could be used to detonate destructive devices were discovered. “I know that the HTMD found in the garage combined with the amount of ammonium nitrate and nitro methane also found in the garage would constitute a “bomb,” FBI special agent Timothy Swanson wrote in the complaint.

Inside Russell’s bedroom, officers found Nazi and white supremacist propaganda, and a framed photo of Timothy McVeigh, the man  executed for killing 168 people in the 1995 Oklahoma City bombing.

The complaint says Russell admitted to being a national socialist (more commonly known as Nazism), and that he had manufactured the HTMD. He also confessed to being a member of the group called Atomwaffen (German for atomic weapon). The Southern Poverty Law Center listed the Atomwaffen as one of 99 active neo-Nazi hate groups.

Russell said when he was in an engineering club at USF in 2013, he used HTMD to boost homemade rockets and send balloons into the atmosphere for testing.

“Based on my training and experience, HMTD is too energetic and volatile for these types of uses,” Swanson wrote in the complaint.

He also wrote that he received confirmation from ATF Explosive enforcement officer Kevin Miner that the HTMD is an explosive, and that probable cause existed that Russell was intending to assemble a destructive device.

Russell was arrested on an FBI warrant May 21 in Key Largo and charged with possessing an unregistered destructive device and unlawful storage of explosive material.

Why Russell was released and ended up in Key Largo two days after the shooting is unclear.

Arthurs was charged with two counts of first degree murder, three counts of armed kidnapping and two counts of aggravated assault.

According to police reports, Arthurs walked into the Green Planet Smoke Shop at 15352 Amberly Dr. in Tampa Palms and pulled a handgun from his waistband. He ordered a store employee and a customer to the floor, asking, “Why shouldn’t I kill you?”

Another customer entered the shop a few minutes later and was also ordered to the floor. Arthurs told the hostages that he had already killed someone and that he was upset because of the American bombings in the Middle East.

When TPD contacted Arthurs, one hostage managed to escape, and police convinced him to allow the other two to leave as well.

After surrendering, Arthurs made several references to Allah, according to the report.

“I had to do it,’’ he told officers. “This wouldn’t have had to happen if your country didn’t bomb my country.”

Arthurs claimed he shot his roommates to prevent them from committing planned acts of domestic terrorism.
