Boston Marathon bombings

A young South Florida amputee and his brother just found out they're getting some star power behind their efforts to raise money for the victims of the Boston Marathon bombings.

Media mogul Oprah Winfrey has pledged $100K toward a charity created by 13-year-old Michael Stolzenberg and his older brother, 18-year-old Harris.

Just five years ago, at eight years old, Michael lost both hands and both feet to a massive skin infection.  

Winfrey told Michael's story to Harvard University's class of 2013 during her commencement address last month.

In Orlando, Fla., early Wednesday "an FBI agent was involved in a deadly shooting connected to the Boston Marathon bombing case," NBC News is reporting. A man who was being questioned by the agent is dead. NPR's Dina Temple-Raston and Carrie Johnson have also confirmed the news.

Just how firm the man's alleged connection to the marathon case is, though, remains unclear.

Trevor Aaronson was running errands when he heard about yesterday's bombings at the Boston Marathon. The news coming across the radio caught his attention, maybe more than the rest of us, and he soon found himself forgetting about his dry cleaning and going to Twitter for clues.
