Officials announced Monday that a fourth body was recovered from the site of the deadly Francis Scott Key Bridge collapse in Baltimore last month.

Salvage crews discovered what they believed to be John Caldwella missing construction vehicle Sunday and alerted the Maryland State Police, the Key Bridge Response Unified Command said in a statement. State police, the FBI, and the Maryland Transportation Authority Police responded to the site and found the victim trapped inside the vehicle.

The victim was transported to the medical examiner's office and identified on Monday, officials said. The name of the victim was not immediately released at the request of the family.

"As we mourn the lives lost and continue the recovery operation, we recognize each missing individual is someone’s beloved friend or family member," Colonel Roland L. Butler, Jr., Superintendent of Maryland State Police said in a statement Monday. "Along with all of our allied law enforcement partners, we pledge to exhaust the physical and technical aspects of their training while deploying every available resource possible."

Authorities have been working to recover the bodies of the six construction workers who died in the collapse on March 26. Eight workers were fixing potholes on the bridge when a cargo ship struck it, causing it to plunge into the Patapsco River.

Rescuers had pulled out two workers, but the six were presumed dead after an hourslong search. Crews recovered two bodies a day after the collapse and a third body was located on April 5.

The three deceased victims recovered were identified as Maynor Suazo Sandoval, 38, Dorlian Castillo Cabrera, 26, and Alejandro Hernandez Fuentes, 35, according to authorities.
