Please summarize the story below in a paragraph assuming the reader is a third-grader. 

The trio are alleged to have thrown rocks at other vehicles that night.

Three other people were injured after rocks were thrown at vehicles within a 45-minute span, the district attorney’s office said. Seven vehicles in all were struck, the statement said.

Bartell's vehicle was the last to be hit that night, authorities have said.

The three people now charged are 12th graders in Jefferson County Public Schools, a spokesperson for the Jefferson County Sheriff's Office said when they were arrested last week.

The three are alleged to have been in another vehicle driving when the rocks were thrown at other vehicles, the sheriff's office said.

In addition to the murder charge, each is charged with seven counts of attempted murder, three counts of second-degree assault and three counts of second-degree attempted assault, according to the district attorney's office.

One of the people whose vehicle was hit by a rock has described seeing another car's headlights in the dark and then hearing "what sounded like a shotgun blast" as his window was shattered.
