MIRAMAR, Fla. – A Florida Highway Patrol trooper and at least 19 law enforcement officers from four different agencies fired their weapons during a recent fatal police-involved shooting in Broward County, according to the Florida Department of Law Enforcement.

The Dec. 5 police-involved shooting remains under investigation, but the FDLE revealed one of the officers was from the Pembroke Pines Police Department, three officers were from the Miramar Police Department and 15 officers were from the Miami-Dade Police Department.

“We have made a tremendous amount of progress on our investigation," Special Agent Troy Walker said about the ongoing probe. “As you can imagine, we have reviewed voluminous amounts of data and conducted several interviews.”

Ordonez, a 27-year-old father of two young girls, was "outgoing and happy," his brother, Roy Ordonez, told CNN. "You never knew when he was sad."

Four people died -- including UPS driver Frank Ordonez -- in the Dec. 5 shooting on Miramar Parkway. The shooting stemmed from an armed robbery at the Regent Jewelers in Coral Gables and a chase from Miami-Dade County to Broward County.

According to the FBI, 41-year-old cousins, Lamar Alexander and Ronnie Jerome Hill, had taken Ordonez hostage when they hijacked the UPS truck in Coral Gables. Ordonez was 27 years old.

Rick Cutshaw, who was driving nearby, was caught in the crossfire and died. He was 70 years old. The Florida Department of Law Enforcement has yet to complete the investigation.
