FORT LAUDERDALE, Fla. – A Broward Sheriff's Office deputy was suspended with pay Tuesday, days after security footage of the Fort Lauderdale-Hollywood International Airport shooting was leaked to TMZ, Broward County Sheriff Scott Israel said in a statement.

"Our investigation is moving forward," Israel said. "We are making progress and aggressively pursuing this case. Today, I suspended a deputy with pay in connection with this active investigation."

The deputy has been identified as Michael Dingman.

Before the Broward County Commission got down to business Tuesday, commissioners addressed the fatal shooting last week at Fort Lauderdale-Hollywood International Airport.

"We are truly shocked and saddened by Friday's senseless act of violence," Broward County Mayor Barbara Sharief said.

Four of the five people killed have been publicly identified. Another six were shot but survived. Authorities said most were tourists in town to catch a cruise.

Authorities said 54 people were taken to Broward Health Medical Center for other injuries or health issues.

"Let's not let this act stop us from living fully," Commissioner Dale Holness said.

The attention now is focused on surveillance video leaked to TMZ over the weekend, which shows the accused gunman, Esteban Santiago, 26, firing at random in the baggage claim area of Terminal 2.

Someone described as a high ranking law enforcement officer with security clearance used a cellphone to record off of a monitor, not realizing that part of their own reflection was captured on the footage that was likely sold to TMZ.

"To know that somebody with that type of security clearance could think that it's OK to leak evidence into a media organization really didn't settle well with us, and it is a crime," Sharief said.

The images are now in the hands of specialists with the FBI.

Sharief offered an apology to the families of the victims about the leaked video.
