SUNRISE, Fla. — Two agents were shot and killed and three wounded while serving a warrant at a Sunrise home Tuesday morning, the FBI confirmed Tuesday morning. After barricading himself in the home for several hours, the suspected gunman is believed to have shot and killed himself, one law-enforcement source said.

Sunrise police said the suspect, a man suspected of child pornography possession, had holed up in his home at an apartment complex at 10100 Reflections Blvd. West.

“Two wounded agents were transported to hospital and are in stable condition,” the FBI said in a statement. The statement did not address the condition of the third agent. The victims appeared to have been taken to the trauma unit at Broward Health Medical Center in Fort Lauderdale. Dozens of police officers from area agencies were already gathered outside by 11 a.m.

FBI Director Christopher Wray on Tuesday afternoon identified the slain agents as Dan Alfin and Laura Schwartzenberger, veteran agents of the Internet Crimes Against Children Task Force program.

“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. The FBI will always honor their ultimate sacrifice and will be forever grateful for their bravery,” Wray said in a statement.

The shooting happened around 6 a.m.
