(SS) Escalating accusations against a former Wilton Manors man have risen from misdemeanor to felony, from state to federal court, from failing to pay a restaurant tab to scrawling profanity on a restaurant window to making online threats to the local LGBT community.

Craig Jungwirth, 50, on Friday pleaded not guilty in a Fort Lauderdale federal courtroom to his most recent charge — a felony accusing him of threatening to "exterminate" gays and alluding to a Labor Day attack that would be more deadly than the June 12 massacre at Pulse, a gay nightclub in Orlando, that left 49 dead and 53 injured.

"I'm gonna be killing you [expletive] .… It's time to clean up Wilton Manors from all you AIDS infested losers," an excerpt from Jungwirth's Aug. 30 Facebook post allegedly said.

The threatening language, peppered with gay slurs and profanity, prompted Wilton Manors and Fort Lauderdale police to step up patrols within their communities.

Jungwirth appeared in court in dark blue inmate scrubs, thick eyeglasses and an overgrown beard. He sat hunched over with his hands clasped between his knees, his handcuffed wrists connected to a chain around his waist.

A known figure to Wilton Manors residents and business owners, Jungwirth has been accused multiple times of harassing behavior, stalking, sabotage, vandalism and trespassing, an affidavit said.

Arrested in connection with the alleged Facebook threats Sept. 3 in Osceola County, Jungwirth arrived Thursday at the Broward Main Jail to face the felony charge. And there he'll remain, for the time being.

The MIT graduate learned at his Friday morning hearing that his bond had been revoked in two pending misdemeanor cases in state court — one stems from accusations that he failed to pay a $300 restaurant bill and the other alleges that he scrawled profane graffiti on a window at Rumors Bar & Grill.

Jungwirth was given an opportunity to resolve the case over the unpaid restaurant bill by attending a misdemeanor diversion program, but his "combativeness" impeded his success, court records show.

Jungwirth on Friday told U.S. Magistrate Judge Patrick Hunt that he was an engineer who made about $3,000 a month and was primary caregiver for his mother. Jungwirth said he did not own a home, was not married and had no children.

Hunt appointed a public defender to represent Jungwirth on the federal charge, which carries a maximum penalty of five years in prison, a $250,000 fine, or both.
