One of her screensavers also showed Sedwick with her head resting on a railroad track.Some of the girls' computers and cellphones were seized in the investigation.
He said the two girls arrested were the major culprits.The sting led to 141 arrests, with Robert Tester among them.But Tester said he was tricked into purchasing the phone after the undercover officer told him he needed money to feed his daughter for Christmas.Florida has a bullying law named after a teenager who killed himself after being harassed by classmates.Amended July 1 to cover cyberbullying, the law leaves punishment to schools, though law enforcement also can seek more traditional charges.The girl who had been dating Sedwick's former boyfriend went to friends around the school and tried to have them turn on Sedwick, Judd said.
