Two veteran FBI agents were killed and three others wounded Tuesday morning around 6 a.m. when a gunman opened fire as the agents attempted to serve a search warrant at an apartment in Sunrise, FL, as part of a child-pornography probe.
The gunman, not yet identified by the FBI, is believed to have monitored the approach of the agents with a doorbell camera and ambushed them through the unopened door with a rifle, law enforcement sources told the Miami Herald .
