Boston Marathon

Running a marathon is not easy. However, try running three marathons back to back. That is one marathon for each person killed in the recent Boston Marathon bombings.

On Monday, the Justice Department announced that it was charging Dzhokhar Tsarnaev with using a weapon of mass destruction that resulted in the deaths of three people at the Boston Marathon last week. If convicted he could face the death penalty or up to life in prison.

A massive manhunt that spanned several Boston communities has come to an end with Boston police announcing that 19-year-old Dzokhar Tsarnaev, the second suspect in the Boston Marathon bombing, has been captured.

The investigation into the Boston Marathon bombing seeped into New Bedford, Mass. on Friday evening with the questioning of several people who knew suspect Dzhokhar Tsarnaev.

A YouTube account believed to be Tamerlan Tsarnaev 's and a Twitter account that could be Dzhokhar Tsarnaev's has been found. The YouTube account includes 17 videos in four categories, including the one "Terrorists."

The second suspect in the Boston Marathon bombing has been captured. Dzokhar Tsarnaev was taken into police custody Friday night -- five days after the bombing that left three dead and left more than 100 injured, police said. The 19-year-old was apprehended after a manhunt that began Thursday night with the fatal shooting of an MIT officer and extended into the evening hours on Friday.

6:55 AM ET:  The AP is reporting that the suspects are from Chechnya, and have lived in the US for at least one year. The surviving Boston bomb suspect has been identified as Dzhokhar Tsarnaev, 19, of Cambridge, Ma. NBC News is reporting that both suspects are brothers. Sources say that the men may have military experience, according to law enforcement officials. 6:30 AM ET: CNN is reporting that

Monday, April 15 is a day that will live in American history when two bombs exploded near the finish line of the Boston Marathon. Hamilton resident Dean Jordan had just finished the race minutes earlier, and was only a block or two away from the explosions.
