The two boys accused of using a fire alarm to lure classmates and teachers into a hail of gunfire have set off the jail fire sprinkler system and gotten into a food fight with other inmates, the sheriff says.

The boys, who are being held in the juvenile wing at the Craighead County jail, were temporarily denied privileges, such as watching television and making telephone calls, Sheriff Dale Haas said Thursday."They don't act any different than the rest of them," Haas said. "In that age group, for juvenile delinquents, to be somewhat destructive is common."
