Yet another child has committed suicide after being bullied on social media for more than a year. 12-year old Rebecca Ann Sedwick jumped to her death at an old cement business in Lakeland, FL., a city half an hour away from Tampa.

She was reported missing on Monday after not returning from school, and her body was found hours later. In a press conference, Sheriff Grady Judd said Sedwick was "absolutely terrorized on social media."

According to Lakeland Ledger:

During their investigation, detectives found multiple social media applications where Sedwick was constantly being cyber-bullied with messages, including “Go kill yourself,” and “Why are you still alive?”

Investigators have identified at least 15 girls who allegedly harassed Sedwick. Their laptops and phones have been confiscated and their parents are cooperating with police.

Judd also revealed to The Ledger that Sedwick had messaged a boy in North Carolina hours before her death, writing, "I'm jumping, I can't take it anymore."

Florida has a law against bullying and cyber-bullying, so the girls could potentially be charged with felony cyber stalking, since Sedwick was under 16-years old.

"If you bully somebody online and it's reported to us and we can build a credible case, we will charge you," Judd told The Ledger.
