Facebook has proven it’s effectiveness as world’s number 1 social networking site by connecting millions of people out there. Not only connecting your office colleagues/friends, but also your long lost buddies which haven’t been seen for ages.

Today, Facebook not only been used to socialize but also to assist police in ongoing investigation. In one recent case, Facebook has been used by Wisconsin Police to gather information of an unidentified murder suspect.

The Police found partially decomposed body of a young in the woods in Fond du Lac county. Despite the normal practice of handing out photos and checking missing persons register, the detectives are still unable to identify the woman nearly a year later.

On the sheriff’s Web site, Fond du Lac police posted an image (created by forensic artists) of the girl known only as the Fond du Lac “Jane Doe.” Detective Soskinski then created a Facebook profile, but Facebook kept removing it. Police obtained a court order from a Fond du Lac circuit court judge in July requiring Facebook to let investigators post the girl’s information. and it turns out the social networking service’s automatic filters were being tripped by the name “Jane Doe” (Facebook requires that all profiles be operated by actual, living human beings).

The legal team from Facebook helped the investigators set up a page for their “Jane Doe”. They have yet to obtain any clue yet but already gathered almost 200 fans and still counting. They are hoping that someone will recognize the composite image of the girl’s face or the clothes she was found in.
