Police began investigating a fiery mystery early Friday in Miami.
Miami police said a driver crashed his or her car into a pole and a parked vehicle at Northwest 39th Street and 17th Avenue. Both vehicles caught fire and a third car crashed into a bush, police said.
"I couldn't believe it at first. I thought the officer might have been joking. When I saw it, I said, 'Wow,'" Harry Puron, whose parked car was burned, said.
Authorities said one of the vehicles damaged a fence across the street at Miami Jackson Senior High School.
Investigators also found bullet casings at the scene, but police said they did not find any victims or drivers, and did not receive any calls about shots fired in the area.
Officers blocked off Northwest 17th Avenue between Northwest 40th Street and 38th Street as they continued their investigation.
Students were led past the crime scene tape by police so they could get to school.
Detectives are interviewing witnesses to try to determine what happened.
Authorities said the vehicle identification numbers are difficult to read on the burned vehicles, making it difficult for police to track down the owners.
Police said they are checking with local hospitals to find out whether any gunshot or car crash victims were treated for injuries.
Police said no blood was found at the scene.
Anyone with information is asked to call Miami-Dade Crime Stoppers at 305-471-TIPS.
