JACKSONVILLE, Fla. — Newly released video from a May 2015 shooting at a school bus that wounded two students shows the bus driver and aide's heroic response, News4JAX reports.

Edgar Robles, 16, fired five shots into a school bus after yelling at students aboard to get off the bus and an unknown person inside the bus spit on him. The bus driver saw the gun in Robles’ hand, and drove the bus away as he started shooting. Two 16-year-old girls were hit while riding the bus and were transported to hospitals with non-life threatening injuries.

In bus surveillance video obtained by the news source that was released on Monday, shots are heard, and about 30 seconds later, a student calls 911 and a bus aide tells the students to get down, News4JAX reports. The bus driver drives the students to safety and gives information to the student who is on the phone with 911 to help police locate them. Meanwhile, the bus aide checks on the students, and after they stop in a safe place, the bus driver helps students as they wait for police to arrive. Some parents called the driver and the aide heroes for keeping calm and helping the students, according to the news source.

Robles was sentenced to 30 years in prison for the attempted murder charges and 15 years for shooting a deadly missile, according to the news source. He must also serve two years of community control and three years of probation after completing his 30-year sentence.
