It happened near 2417 N.W. Ninth Avenue in Wilton Manors, just north of Fort Lauderdale, at around 2:50 p.m. ET Monday, according to the Broward County Sheriff’s Office. Authorities were urging drives to avoid the area, which is blocks away from roughly a half-dozen schools.
The sheriff’s office said it was still gathering details about the case and declined to identify the victims or elaborate on the cause of the crash.
Details on the conditions of the three surviving victims were not immediately available.
Witnesses reportedly told CBS’ Miami affiliate that the driver was speeding and cut around a stopped school bus.
Investigators were asking anyone with information to call Broward County Crime Stoppers at 954-493-TIPS.
