Google Person Finder Available for Boston Marathon Explosions

If you need help tracking down loved ones at Monday's Boston Marathon, you can try Google's Person Finder, a tool the company built following the 2010 earthquake in Haiti.

Google has activated the tool this afternoon for use following the deadly Boston Marathon explosions.

Google says its Person Finder is tracking about 800 records at the moment.

You can also call a hotline at 617-635-4500 or use The Red Cross Safe and Well tool to help located runners.
