Police in central Florida said Rebecca was tormented online and at school by as many as 15 girls before she climbed a tower at an abandoned concrete plant and hurled herself to her death Sept. 9. She is one of at least a dozen or so suicides in the past three years that were attributed at least in part to cyberbullying.
The sheriff said they were still investigating the girls, and trying to decide whether the parents should be charged.
"I'm aggravated that the parents aren't doing what parents should do," the sheriff said. "Responsible parents take disciplinary action."
About a year ago, the older girl threatened to fight Rebecca while they were sixth-graders at Crystal Lake Middle School and told her "to drink bleach and die," the sheriff said. She also convinced the younger girl to bully Rebecca, even though they had been best friends.
The girls repeatedly intimidated Rebecca and called her names, the sheriff said, and at one point, the younger girl even beat up Rebecca at school.
