In the chaos and mayhem that followed the Boston Marathon bombing, many people were frantic to learn the fate of friends and loved ones who were either in the race or watched it from the sidelines.

Two explosions rocked the finish line of the Boston Marathon this afternoon, leaving at least three dead and dozens injured, the Boston Police Department reports.
