Federal prosecutors say a large weapons cache was found at a New Jersey man's home after he was involved in an auto accident last month.

State police found numerous weapons and ammunition inside Joseph's Rubino's vehicle after it crashed on July 24. They later executed search warrants on the vehicle and at Rubino's home in Lafayette Township.

Authorities say numerous guns were found in the home — including rifles, shotguns and handguns — along with high-capacity magazines, ammunition, numerous silencers, a grenade launcher, an assault rifle scope, ballistics vest and other related items.

Officers also allegedly found 70 grams of methamphetamine, seven kilograms of marijuana, 200 marijuana vape cartiridges and white supremacist literature and paraphernalia. A box in the home contained clothing and bumper stickers with "SS Bolts" — common neo-Nazi symbols — and a document containging racist material and 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.

It's not known if Rubino's retained an attorney.
