FRANKLIN, N.J. (CBSNewYork) -- A New Jersey emergency medical technician is under arrest, accused of stockpiling assault rifles, handguns and semi-automatic weapons inside his home.
Authorities say 25-year-old Michael V. Zaremski, of Green, made the weapons himself.
Zaresmki faces more than 35 charges after police seized an arsenal of weapons from his home on Old Pond Lane.
"It's really shocking, I guess," neighbor Kyle Youst said.
Youst says he never saw any sign that Zaremski, who worked as an EMT with Hackettstown EMS, was manufacturing weapons.
Det. Nevin Mattessich says the investigation started after a complaint of domestic violence from someone outside the family.
"Posted some insensitive items, kind of anti-Semitic, so we started looking into that. That lead into us conducting some search warrants into his vehicle, his phone and his residence," he said.
It wasn't until Friday that they made the discovery.
"That's when we came across several high-powered weapons, assault rifles, 17 magazines completely loaded with 30-plus rounds of ammunition in them," Mattessich said.
Weapons that he says Zaremski was making.
"He put several pieces together to make these high-powered weapons," Mattessich said.
Mattessich says when Zaremski came to the police station to speak with detectives he was actually carrying a loaded handgun inside of his EMT jacket.
As for what Zaremski was planning on doing with the guns and ammunition he's accused of putting together, police say that's still under investigation.
Police haven't said how Zaresmski got a hold of the materials to make the weapons.
