TAMPA, FL. - Over 75 first responders from The Tampa Bay area are in Surfside, helping with search and rescue efforts for the collapsed condo.

The official death toll in the Surfside, Fla., building collapse rose to nine on Sunday, after search-and-rescue teams recovered four additional bodies overnight.

Late Saturday, four of the victims were identified: Stacie Dawn Fang, 54; Antonio Lozano, 83; Gladys Lozano, 79; and Manuel LaFont, 54.

Still, more than 150 people still remain unaccounted for – and as rescue operations stretch into a fourth day, authorities and loved ones fear the death toll could go much higher.

Tampa, Hillsborough and St. Petersburg Fire Rescue crews are part of Task Force Three.

There, they have taken generators, search dogs, and every toll they'd need for their seven day deployment.

"There's a lot of things logistically that support the men and women up on those pioles" said Steven Lawrence, Urban Search and Rescue FL Task Force 3.

The team works for 12 hours at a time. Officials say their deployment could last longer if needed.
