A patrol sergeant with experience as a negotiator telephoned Menyhar, who came out of the house about two to three minutes later, said Lt. Sean Redmond, spokesman for the Cherry Hill Police.
"He came out very peacefully, really gentleman-like," Redmond said. "No weapons or anything, he came out and was placed under arrest."
Police escorted Menyhar's wife from the house.
Inside, police found what they described as "a cache of weapons including rifles, pistols, black powder weapons and numerous other edged weapons." Multiple bullet holes were also found throughout the house, according to the release.
It was unclear what caused Menyhar to begin firing inside the house. As far as police could tell, Redmond said, the shooting was unprovoked. A domestic dispute was not suspected, Redmond said.
Menyhar was charged with possession of a stun gun and two counts of possessing high-capacity magazines.
He was also charged with illegally possessing weapons. Menyhar falls under a group of people who are not permitted to possess weapons under New Jersey law, according to the charge. Redmond declined to provide details.
Menyhar was remanded to county jail on $27,500 bail.
