Polk City, Florida -- One person is dead following a 3-car accident on State Road 33 in Polk City.

The crash occurred around 3:00 p.m. on SR 33 North near Grimes Road.

Investigators say 20-year-old Nidaeus Sierra had to brake hard to avoid hitting a car that suddenly stopped in front of him, causing a 1999 GMC Yukon behind him to strike the rear of his car before entering the path of a 2009 Ford Mustang heading in the opposite direction.

The driver of the Mustang was declared dead at the scene. His identity has not been released.

Deputies say a child in the Yukon was airlifted to Arnold Palmer Hospital in Orlando with serious injuries. The child's mother was also airlifted to Lakeland Regional Medical Center with injuries.

Sierra and his passenger were not injured. Both were wearing seatbelts.
