the suspect hasn't been released.

NBC 6's Jamie Guirola, Alyssa Hyman and Kim Wynne have the latest on the two FBI agents who were killed while serving a search warrant for a child porn case in a Sunrise neighborhood.

 In accordance with FBI policy, the shooting incident is under investigation by the FBI's Inspection Division. The review process is thorough and objective and is conducted as expeditiously as possible under the circumstances,  the FBI said in a statement.

Multiple sources told NBC 6 that the suspect had placed cameras outside the unit and the suspect was aware the agents were approaching. Sources said the gunfire started before the agents were in position to knock and seek cover.

Sunrise Fire Rescue officials confirmed the shooting took place near 10100 Reflections Boulevard West after 6 a.m.

Footage showed officers and agents with several law enforcement agencies at the scene, including multiple SWAT teams and vehicles, fire rescue vehicles and medical examiners.

Police remained at the scene Tuesday morning and had surrounding streets closed off as a result.

The area surrounding the scene is safe but residents were told to remain inside their homes, police said.

Piro said Schwartzenberger, 43, had been with the FBI since 2005, and leaves behind a husband and two children. Alfin, 36, had been with the FBI since 2009 and leaves behind a wife and a child.

 The FBI is a family. Our chosen profession is fraught with danger. The grim reality has taken two of our best from our family,  Piro said.

As news of the agents' killing spread, officials from throughout the state and the country were offering their condolences.

President Joe Biden said he was briefed on the incident earlier Tuesday.

 I can only imagine how these families are feeling today,  Biden said.  One of the things when you are in a combat zone in the military or you're an FBI agent or a police officer, every family, when they put that shield on and go out in the morning dreads the possibility of receiving that phone call. My heart aches for the families...It's a hell of a price to pay. 

President Joe Biden extended his sympathies to the families of the two FBI special agents who were killed while executing a search warrant in Sunrise, Florida, on Tuesday.  Every family just, when they put that shield on and go out in the morning, dreads the possibility of… receiving that phone call and my heart aches for the families. 

 These Agents were working to protect the most vulnerable in our society. FBIAA stands with the Agents' families and pledges our support to them during this difficult time,  read a statement from the FBI Agents Association, comprised of more than 14,000 former and current agents.  FBI Special Agents risk their lives to protect our country, and the loss of these Agents is devastating to the entire FBI community and to our country. 

Sen. Marco Rubio called the shooting a  cowardly act  and said he and his wife were praying for the agents' families.

 It serves as yet another reminder that the courageous members of our law enforcement community put their lives on the line every day to make our communities safer from the type of sick, depraved people who would exploit and prey on our children,  Rubio said in a statement.
