The Queens man accused of gunning down a would-be mugger earlier this week was arraigned Friday on dozens of gun charges related to the weapon he used in the incident and for allegedly stockpiling illegal firearms in his apartment.

Charles Foehner, 65, was slapped with 25 counts of criminal possession of a weapon for using an unlicensed gun to fatally blast mugger Cody Gonzalez, 32, in a Kew Gardens driveway Wednesday — and for allegedly keeping an arsenal of illicit handguns, revolvers and rifles at this home in the quiet neighborhood.

He was held on $50,000 cash bail following the arraignment in Queens Criminal Court.

“My office is charging Charles Foehner with multiple counts of criminal possession of a weapon. These are the charges factually supported by the evidence,” Queens District Attorney Melinda Katz said in a written statement.

Foehner has not been hit with any charges for fatally shooting Gonzalez.

Foehner’s wife, Jenny Speed, sobbed outside court ahead of the arraignment, telling reporters her husband is “a really good guy.”

“People love him. Everybody loves him,” she added.

Foehner had been walking home at about 2 a.m Wednesday after stepping out for cigarettes when Gonzalez, an erratic career crook, confronted him on the street, cops said.

Police said the would-be mugger, who demanded smokes and cash, was wielding an object, which Foehner believed to be a knife but later turned out to be a pen.

Surveillance video of the encounter allegedly shows Foehner whipping out a handgun and pointing it at an erratic Gonzalez. He opened fire when Gonzalez suddenly lunged at him, the video shows.

The slain robber — who had at least 15 arrests dating back to 2004 and a record of mental illness — died in the street. Cops found a pen in the slain man’s right hand.

During questioning, Foehner cited the city’s crime as the reason why he was armed when confronted by Gonzalez, Queens Assistant District Attorney Joseph Randazzo said Thursday.

“Last night I was carrying a firearm because of the way that the city has been in the last three years. I read the crime stats and I see so much crime,” Foehner told the investigators, according to prosecutors.

His arrest comes after Foehner griped to The Post just a few years earlier about rampant crime in his neighborhood.

“This isn’t our nice little neighborhood anymore,” Foehner had said in August 2020 article about a since-shuttered hotel on Queens Boulevard that locals griped had turned into “a flophouse.”

“People come down the block and key a car as they pass it. Drug deals are going on in the lobby.”
