RCMP believe missing teen was in touch with Calgary man over the Internet.

Staff Sargeant Russ Shapka with the High River RCMP says they're following a few leads in the Natacha Sibbet case.

They took Sibbet's computer to the Technological Crimes Unit in Calgary today, on her family's suggestion she was talking to a Calgary man over the Internet.

They've also contacted Sibbet's ex-boyfriend in Lethbridge.

Shapka says it's hard to believe no one's seen the local teen for almost two weeks.

"I'm quite surprised that, considering the prominence the press has given it, we haven't had a single call."

She's five foot nine, about 190 pounds, with short dark hair and green eyes.

If you have any information on Natacha's whereabouts, please contact the RCMP at (403) 652-2357.
