Two children were killed and four others were injured when a car crashed into them and fled the scene in South Florida on Monday, according to authorities.

The Broward County Sheriff's Office, along with Wilton Manors Police and Fort Lauderdale Fire Rescue, indicated in a news release that they were investigating what transpired outside an apartment complex in Wilton Manors, Florida.

Any of the children's ages were not immediately available from the sheriff's office. The hospitalized youngsters were "severely injured," said Steven Gollan, a battalion chief with the Fort Lauderdale Fire Department, at a news conference Monday night.

“This event is a horrific event any time of the year, let alone right after the holidays," Gollan said.

Shaunta Adams, who had just driven away from her apartment, claimed the car sped up on a sidewalk to get past a bus before hitting the youngsters.

“By the time I looked up, I saw him going around the bus and I see him hit the damn kids,” Adams told the South Florida Sun-Sentinel. “I jumped out of my car, my car was still running, I ran up and saw the first girl on the ground. I knew she was dead. I go to the second kid and I see him dead.”

When Wallen Johnson, who lives across the street, heard screams, she went outside and saw two bodies in the parking lot, as well as another youngster lying on the ground down the road.
