Teen Slain by Facebook 'Friend': Cops

Australian police are urging Facebook members to make themselves less readily identifiable in real life after an 18-year-old woman was found murdered, allegedly by a "friend" from the website. Nona Belomesoff's body was discovered in a creek bed Friday night. Christopher James Dannevig, 20, has been charged with murder and is being held without bail, the Sydney Morning Herald reports.

The pair met on a dating site and got to know each other through Facebook, where Dannevig said he worked for an animal welfare organization and offered Belomesoff a job. "She loved animals and saw this as an opportunity to follow her dream," her brother told The Age. "This is an ongoing problem that young people and members of the public need to be cautious of," a police detective warns.
