Two families in Leander say they're experiencing "Cyber Bullying" in a way not many have ever seen before.
Two mothers say a former classmate of their daughters' is sending death threats...even stalking them.
We spoke with Leander Police and they confirm this is a case they are investigating but couldn't give us much more information than that because of all of the minors involved.
So what follows is the family's side of the story.
Christine Young and Marti Coffey say their pre-teen daughters, Julia and Melody were friends with an unnamed girl at Stiles Middle School in Leander.
After a disagreement, Julia and Melody stopped being friends with the girl. That's when the mothers say a series of social media messages started to pour in from this girl to their daughters.
Soon, the harassing messages turned into death threats.
The mothers claim their daughters' social media accounts were hacked on several occasions...and they even had their phones checked for bugging and spyware because of the private information the girl seemed to know.
Christine and Marti began contacting law enforcement as soon as these messages started coming in, but they needed proof the girl was really the one behind the computer.
"Personal conversations that the girls had had been mentioned in some of these messages. Inside jokes were mentioned in some of these messages. You know, things that this girl would have known and only this girl would have known," Young said.
The two mothers told us they know it sounds crazy. Saying if it wasn't actually happening to them, they wouldn't believe it themselves.
Marti Coffee says they don't believe the little girl is in on this alone.
"I just think we're dealing with something they've never dealt with before. This is not just one person. This is a network of people, this is more than one person, I think it's beyond what they've ever come across. I believe that these people, this group of people or network of people believe they're not going to get caught...and the way it looks right now, I don't think they are either. I don't think the police are capable of catching people like this," Coffey said.
Christine and Marti insist that their daughters are not involved in this, saying they have witnessed some of these messages come in when their daughters are sitting next to each other.
Both mothers even contacted the FBI about this.
They've pulled their daughters out of public school and they say they're still getting messages from this girl.
