SUNRISE, Fla. — Two FBI agents are dead and three agents were wounded in a shooting on Tuesday morning while serving a federal search warrant in a child exploitation case in South Florida, the FBI said, who added that the subject was also fatally shot.

During the standoff, the subject — whose name has not been released — barricaded himself inside a home before he was killed, said FBI Miami Special Agent Michael D. Leverock.

A total of three agents were wounded, but two of them were taken to area hospitals and are stable, Leverock said.

FBI Director Christopher A. Wray identified the two slain agents as Daniel Alfin and Laura Schwartzenberger. Wray said one of the three injured agents did not require hospitalization.

“Every day, FBI Special Agents put themselves in harm’s way to keep the American people safe,” Wray said in a statement. “Special Agent Alfin and Special Agent Schwartzenberger exemplified heroism today in defense of their country. The FBI will always honor their ultimate sacrifice and will be forever grateful for their bravery.”

Law enforcement agencies swarmed the neighborhood in the Fort Lauderdale suburb of Sunrise after the shooting.

Another large contingent of officers gathered outside a Fort Lauderdale hospital where victims were taken, according to television video. The agents had arrived to serve a federal search warrant in connection with a case involving violent crimes against children, Leverock said.

"A team of law enforcement officers were there to execute a federal court-ordered search warrant in furtherance of a violent crimes against children case," stated the FBI in a press release.

The Sunrise Police Department tweeted about the heavy police presence and the closure of surrounding roads.

The shooting happened around 6 a.m. in a middle-class neighborhood of single family homes, duplexes and apartment buildings. In  the vicinity of 10100 Reflections Blvd., Sunrise, stated the FBI. 

Hours later, Sunrise Police urged residents of Water Terrace to remain inside their homes while law enforcement blocked the entrances to their community.

Julius McLymont, whose house borders the Water Terrace apartment complex, described what he heard.

“Boom boom boom boom,” he said.

He thought it was a car backfiring but about two minutes later he heard another volley of about five shots. He went outside and looked over his fence as police cars and ambulances rushed in. Then he saw officers working on someone lying on the ground, who was then loaded into an ambulance.
