Do you have a friend or family member who was at the Boston marathon today? Or do you have information about someone who is there? Then you’d better go to Google Person Finder.

The tool will help you check up on the whereabouts of a loved one, as well as share information about someone’s location. Here is more from the page: “All data entered will be available to the public and viewable and usable by anyone. Google does not review or verify the accuracy of this data.”

If you have collected information on your site and you’d like to combine it with Google’s data, you can download and upload data from Google Person Finder. Follow this link to find out more.
