BROWARD COUNTY, Fla. – A child was killed after a bad crash in northern Broward County caused major backups on Tuesday afternoon.

It happened on US-27 at approximately 2:40 p.m. just south of the Palm Beach County line.

The crash caused police to shut down a portion of the road near Mile Marker 47 for a time in both directions.

A total of two adults and seven children required treatment, according to authorities.

A black Nissan sedan could be seen badly damaged. Somehow a tractor trailer struck the car that was on the side of the road.

All nine of the injured victims were traveling in the Nissan, police said.

Two children were rushed to Delray Medical Center and two others were taken to St. Mary’s Medical Center, according to the Florida Highway Patrol.

Authorities said the remaining three children, along with the two adults, were rushed to Broward Health Medical Center, where one of the children was pronounced dead.

Family members told Local 10 News that the boy who died in the crash was 11 years old.

They also said the Nissan had pulled off to the side of the road because of a flat tire and while waiting for AAA, the truck slammed into the car.

Police have yet to provide any details on what caused the crash.
