Federal authorities say that a Sussex County man possessed a weapons arsenal, along with white supremacist and racist propaganda.

The U.S. Attorney’s Office says that New Jersey State Police found the items after Joseph Rubino, of Lafayette Township, was involved in an auto crash in July.

State police found numerous weapons and ammunition inside Rubino's vehicle after it crashed on July 24. They later executed search warrants on the vehicle and at his home, according to authorities.

Authorities say numerous guns were found in the home - including rifles, shotguns and handguns - along with high-capacity magazines, ammunition, a grenade launcher and other related items. Officers also allegedly found methamphetamine, marijuana and white supremacist literature, including a document allegedly titled “[N-word] Owner’s Manual,” “purporting to be an instruction manual for owning a slave,” according to the U.S. Attorney’s Office.

The 57-year-old Rubino faces weapons charges and a count of possessing methamphetamine with intent to distribute. He was due to make his initial court appearance Tuesday, but that hearing was later postponed.

Rubino could face life in prison if convicted of the crimes.
