Investigator gives Craiglist warning

Authorities believe the person who killed a woman in a Boston hotel could be picking his victims through the ads posted on the Craigslist website. A private investigator who specializes in computer cases says the connection to Craigslist is a double-edged sword.

Some information can be traced back to the suspect's computer, but this suspect may not have used a computer from home.

Private Investigator Vic Pichette says that Craigslist is not monitored by moderators, meaning anyone using the site for any service should be careful of the contacts they make.
