Craig Jungwirth, 50, is suspected of making the threats on Facebook this week

The FBI and local authorities in Florida are investigating threats to 'exterminate' LGBT people living in suburban Fort Lauderdale - and the alleged culprit behind the alarming posts has been revealed as an openly gay man.

According to investigators, Craig Jungwirth, 50, has unleashed a series of foul-mouthed homophobic status updates on his Facebook page threatening violence against LGBT people living in Wilton Manors - a predominantly gay and lesbian city located just 3 miles north of Fort Lauderdale.

Jungwirth's posts make mention of the deadly June 12 attack at Pulse nightclub in Orlando that killed 49 people and injured more than 50.

One message reads: 'None of you deserve to live. If you losers thought the Pulse nightclub shooting was bad, wait till you see what I'm planning for Labor Day.'

In another post, the suspect allegedly writes: 'You can never catch a genius from MIT and since you f*****s aren’t dying from AIDS anymore, I have a better solution to exterminate you losers.'

It continues, 'I'm gonna be killing you f***** faster than cops kill n******. It's time to clean up Wilton Manors from all you AIDS-infested losers.'

The messages appeared on a social media account associated with Jungwirth earlier this week. Facebook has since deleted his page.

Wilton Manors Police Chief Paul O'Connell tells local news outlets the FBI has made contact with Jungwirth, who has denied writing the threatening posts. He says his agency is conducting an 'intense investigation.'

The online threats put the LGBT community in Wilton Manors on high alert, with many local business owners scrambling to bring in extra security for the Labor Day Weekend festivities.

Police Chief O’Connell released a statement saying in part that his department ‘will have increased patrol and visibility throughout the holiday weekend, working with local bars and restaurants in an effort to beef up private security,’ reported WSVN.

Disgruntled: Jungwirth reportedly has become angry with some members of the community for failing to support his business venture

Nick Berry, the owner of Rumors Bar and Grille in Wilton Manors, says he has clashed with Jungwirth in the past, and he believes the man is capable of carrying out the threats, reported ClickOrlando.

According to Berry, Jungwirth is the same person who was captured on surveillance video defacing his bar back in May.

The bar owner tells CBS Miami that Jungwirth, who organizes social events for LGBT people, has become unhinged after local business owners failed to support him when he bought rights to a weekend theme party called Bear Beach Weekend in May.

A gay publication later accused Jungwirth of defrauding people by selling $100 tickets to a party held on a free public beach, reported Miami Herald.

'Even though he's gay, and he is attacking gays, this is clearly a hate crime, ' Berry said.

Jungwirth has a past criminal record that includes charges of stalking and fraud, according to NBC Miami. As of Thursday morning, he has not been arrested in connection to the threats.

According to his LinkedIn page, the 50-year-old has a Bachelor's degree in mechanical engineering from the prestigious Massachusetts Institute of Technology.
