Suffolk County police say they’re investigating Internet messages sent before and after a West Islip teenager killed herself.

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

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. He says they’re taking action because of how upsetting it is for those she left behind when she was found in her bedroom Sunday.
