(AP) — It was a cold-hearted online post that a Florida sheriff says hastened the arrest of two girls, aged 12 and 14, in the bullying-suicide case of Rebecca Sedwick.

Polk County Sheriff Grady Judd repeated the older girl’s Facebook comment almost word for word at a news conference Tuesday.

“‘Yes, I bullied Rebecca and she killed herself but I don’t give a …’ and you can add the last word yourself,” Judd said.

Authorities say 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. But the sheriff says the two girls arrested were primarily the ones who bullied Rebecca. They have been charged with stalking and released to their parents.
