Two FBI agents were killed and three others were injured in a shooting Tuesday morning as authorities were executing a search warrant at a home in Sunrise, Florida.
The gunman was also killed, the FBI's Miami bureau said. Authorities identified him Wednesday as David Lee Huber, a 55-year-old man from the area.
The incident began just after 6 a.m. at an address on Nob Hill Road, according to police in Sunrise, near Miami.
Authorities were at the home to serve a federal court-ordered search warrant in a case involving violent crimes against children, the FBI said.
Special Agents Daniel Alfin and Laura Schwartzenberger were killed, FBI Director Christopher Wray said in a statement.
Two of the injured agents were taken to the hospital, where they were stable. One of the agents was later released, the FBI said Wednesday.
The third did not require hospitalization.
"Every day, FBI special agents put themselves in harm's way to keep the American people safe. Special Agent Alfin and Special Agent Schwartzenberger exemplified heroism today in defense of their country," Wray said.
"The FBI will always honor their ultimate sacrifice and will be forever grateful for their bravery. We continue to stand by our FBI Family, and the families of these special agents, in the days to come, bringing every resource we can to get through this together," Wray said.
Police said earlier Tuesday that the suspect was barricaded inside a home and that paramedics were on the scene.
In a tweet just after 9 a.m., police said the scene was safe but asked residents in the area to stay in their homes because of the investigation.

NBC News security contributor Frank Figliuzzi, a former assistant director of the FBI, said Tuesday was "an awful day in FBI history."
He said executing a warrant related to child pornography or pedophilia cases is highly dangerous.
"The risk is elevated because that person's reputation in the community will be lost in that instant," he said in an interview with "NBC Nightly News."
"And the reality of who they are, versus the persona they've put out to the public, comes to a crashing halt. That means you see incidences of suicide during the service of search warrants, and you see now violence against the law enforcement agents."
President Joe Biden offered his condolences on Tuesday night.
"Our hearts go out to the families of the FBI special agents," Biden told reporters at the White House. "I was briefed earlier today and I know the FBI is gathering information about how this happened and what happened. I can only imagine how these families are feeling today."
Alfin joined the FBI in 2009 as an agent with the Albany, New York, office. He began working in Miami in 2017.
Thomas Relford, Special Agent in Charge in Albany, said Alfin "did outstanding work within our criminal and cyber programs" and had a "tremendous impact on the FBI's Violent Crimes Against Children program."
Schwartzenberger joined the FBI's Albuquerque office in 2005 and moved over to the Miami bureau in 2010. FBI Miami Special Agent in Charge George Piro said she had over seven years of experience working cases involving crimes against children.
