Judd, clearly upset about the incident, expressed frustration that neither girl's parents were willing to bring them in for questioning. He said he was astonished to find out that the 14-year-old in the case was still being allowed to post to the Internet after what had happened.
He said he would charge the child's parents if he could, but said investigators were aware of no "obvious charges" against them.
"I'm aggravated that the parents aren't doing what they are supposed to be doing," he said.
Norman said she blamed the parents of the two girls and the staff at the middle school. She and Rebecca reported the bullying to the school, she said.
While bullying was not in itself against the law, Judd said, the girls' actions allegedly harassing Rebecca in school and online formed the basis for the stalking charge. He did not expect any other charges would be filed.
No court date has yet been set for the girls, who Judd said will probably not see any time in juvenile detention because they have no previous criminal records and the charge is a class-three felony, one step up from a misdemeanor under Florida law.
Had Rebecca been 17 or older, he said, authorities could have filed nothing more than misdemeanor charges.
He implored parents to take more responsibility for the actions of their children online.
"We've lost sleep over that child dying needlessly, and we want to see things change," he said. "We want to never, ever, ever investigate a case like that again."
