(UPI) -- Two girls have been arrested in connection to the death of 14-year-old Rebecca Sedwick, who committed suicide on September 9 after enduring months of bullying.
The arrests were made after Guadalupe Shaw posted an insensitive message about Sedwick on her Facebook page.
"Yes IK I bullied REBECCA nd she killed her self but IDGAF," the 14-year-old wrote. IK is slang for "I know" and IDGAF stands for "I don't give a [expletive]."
Polk County sheriff Grady Judd said the 14-year-old's parents claimed their daughter's account had been hacked, but police doubt that this was the case.
"She forced this arrest today," Judd said of the girl's decision to post the message Saturday.
Katelyn Roman, 12, was also arrested for the cyber bullying of Sedwick. Both girls were taken from their homes and were charged with aggravated stalking. They were booked Monday and released to their parents later that day.
Judd said Shaw was the mastermind behind the bullying and that it all began because Sedwick had once dated the girl's current boyfriend.
In addition to cyber-accosting Sedwick, Shaw once physically assaulted her and recruited Roman, her best friend, to bully Sedwick as well, Judd said.
Some of the messages that prompted Sedwick to jump to her death from the top of an abandoned concrete plant were, "you should die" and "why don't you go kill yourself," according to Judd.
The sheriff expressed frustration that the girls' parents would allow them to continue to post on Facebook after the tragedy and that they refused to turn the girls in. He said he would charge them if he could.
"I'm aggravated that the parents aren't doing what they are supposed to be doing." Judd said.
While bullying isn't exactly against the law, Judd said the girls' cyber and physical harassment formed the basis for the stalking charge. He does not expect other charges to be filed. Because stalking is a class 3 felony and the girls have no criminal record they're not likely to spend any time in juvenile detention for their crime.
Judd urged parents to monitor and take responsibility for their kids' actions on the Internet.
"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."
