The last victim of the Florida International University bridge collapse has been recovered, law enforcement said during a Saturday night news conference.

Although the Miami-Dade County Police Departmen expected to find more victims, the death toll stands at 6.

Three people and two vehicles were pulled from the rubble early Saturday. The victims were identified as Rolando Hernandez, Oswald Gonzalez and Alberto Arias. Hernandez was found inside a gold Jeep Grand Cherokee, while Gonzalez and Arias were found inside a white Chevrolet truck.

A fourth victim was identified as Navarro Brown. Brown was taken to Kendall Regional Medical Center, where he died from his injuries.  

Officials said they will go back to the site and search once more to make sure no one else is underneath the rubble.

"We're pretty confident that no one's left," said Juan Perez, director of the Miami-Dade Police Department.

The bodies have been taken to the Medical Examiner's Office so they can be turned over to family members.

The newly-installed pedestrian bridge collapsed on Thursday, trapping several people and vehicles underneath. 

Several agencies are conducting investigations into the pedestrian bridge collapse. 

The Miami-Dade Police Department is conducting a homicide investigation, while the National Transportation Safety Board conducts an independent investigation to determine the cause of the accident and to help prevent it from happening again. 

The bridge, which went up last weekend, cost $14.2 million and was supposed to open in 2019 as a safe way for students to cross the busy road. It was the first of its kind to be built using an accelerated bridge construction method.

On Friday, the Florida Department of Transportation released a transcript of a voicemail left by the lead engineer on the FIU pedestrian bridge project noting "cracking" seen on the bridge two days before it collapsed.

The voicemail was left on a landline, according to FDOT, and not received by its intended recipient until Friday, March 16, as the employee was out of the office on assignment.

FDOT said in a release that it was the sole responsibility of the FIU design build team to identify and address life-safety issues and properly communicate them, and that they were not made aware by the FIU design team of any scheduled "stress testing" of the bridge following its installation.

FDOT plans to conduct an internal review in connection with the collapse.
