The 14-year-old instigated the bullying after she started dating Rebecca's former boyfriend, Judd said.

The 12-year-old girl was once Rebecca's friend — but the 14-year-old girl turned her against Rebecca.

The girls "repeatedly and maliciously" harassed Rebecca while all three attended Crystal Lake Middle School in Lakeland, investigators said.

"Several students corroborated stories of both girls bullying Sedwick on different occasions, through name-calling, intimidation, threats to beat her up, and at least one actual physical fight," a Sheriff's Office report said.

Rebecca brought it all to an end by jumping to her death from a silo at an abandoned concrete factory on Sept. 10. But even after death, the cruelty didn't cease, family members and investigators say.

"Yes ik (I know) I bullied Rebecca nd she killed her self but IDGAF (I don't give a (expletive)).

That message — posted Saturday on Facebook by Rebecca's 14-year-old persecutor — ended with a heart symbol, and an arrest.

On Monday, Polk County deputies charged the author of the post and a 12-year-old girl with aggravated stalking after they identified them as Rebecca's main tormentors.

The morning Rebecca took her life, she posted a message to a North Carolina boy whom she reportedly met once at the airport: "I'm jumping and I can't take it anymore," the text read.

The boy did not tell anyone his friend was suicidal.
