SUFFOLK COUNTY, N.Y. -- Police are investigating a series of vicious Facebook messages posted before and after a popular teenager committed suicide.

Even after 17-year-old Alexis Pilkington died, the harassing internet messages keep coming, posted on a page meant to stand as a tribute.

"If they broke it down and they found these cowards ... there's probably a handful of them, maybe five maybe ten, who knows, but I'm also a karma guy," Thomas Pilkington, Alexis' father told PIX News. "What goes around comes around."

Some of the Facebook messages are disrespectful, others are cruel and hurtful, but the family of Alexis Pinkington wants her friends and classmates to just ignore them.

"Their world has been rocked, let alone with Alexis' death but with what has now come on the internet afterwards," the teen's dad said. "We don't want to give these people an audience."

"Children don't go there, don't go there," said Paula Pilkington, Alexis' mom, "She's gone forever and now we have to deal with the heartache."

Michael Stracuzza is the father of one of Alexis' friends.

He says he's sending prosecutors information on all the harassing posts put on a Facebook memorial site.

Stracuzza says that neither he nor Alexis' family thinks the internet posts led to her suicide.

But he says they want the responsible parties prosecuted because of the pain that the messages are now causing those Alexis left behind when she was found in her bedroom Sunday.
