Janesville School officials are investigating what appears to be a student prank that caused a panic.
District Administrative and Human Services director Steve Sperry says the hoax was started by a group of middle school student athletes, who posted online on Facebook that a bus had been involved in a rollover crash and a coach was killed.

No such crash actually occurred though and the district had to send an emergency alert out to parents.
Sperry says the seven students they believe are responsible have been cooperative, but they could still face disciplinary action for starting the hoax.
