The suspect in the Florida shooting that left two FBI agents dead and three wounded was identified by sources as a 55-year-old man who lived alone in the Sunrise apartment complex.

David Lee Huber was the target of a child-porn search warrant being served by the agents early Tuesday when he spied on the feds through a doorbell camera and opened fire with an assault-style rifle, sources told The Post.

Huber largely kept to himself at the Water Terrace Apartments and did not appear to have befriended any of his neighbors, a former tenant said.

The shooting around 6 a.m. Tuesday left veteran FBI agents Daniel Alfin and Laura Schwartzenberger dead — and three others wounded, two hospitalized in stable condition.

Schwartzenberger reportedly was killed instantly, but Alfin was able to return fire despite being hit multiple times and mortally wounded, a law enforcement source told WFOR-TV in Miami.

Authorities said Huber barricaded himself inside the first-floor apartment and is believed to have taken his own life, according to reports.

Sources told WFOR that in addition to the assault-style rifle, Huber had several other weapons in the apartment. 

Alfin, 36, and Schwartzenberger, 43, had long careers in combating child pornography and sex-trafficking cases in South Florida, the agency said.

Federal authorities have not released details of the investigation that led to the search warrant, or the names of the agents who were wounded.

An initial review shows Huber largely had vehicle and traffic violations on his record but there were no reports of sexual crimes or jail time in Florida. 

He previously ran a computer business, WSVN-TV reported.

He was married in 2000 but the couple, who have two young children, separated in 2009 and divorced in 2016, the station reported. 

Federal Aviation Administration records show he held a commercial pilot’s license issued in 1994, authorizing him to fly both single- and multi-engine aircraft.

The shooting remains under investigation.
