The latest on the Boston Bombing investigation, fears for security at the London Marathon and Sochi Olympic Games, and a former dictatorship is rewarded for good behavior.

Authorities are now trying to determine the motive of the Tsarnaev brothers, one killed and the other arrested and to be charged in the deadly bombing at the Boston Marathon as well as the shooting death of a police officer.  19-year old Dzhokhar Tsarnaev has been revealed to be a pretty poor student at the University of Massachusetts.   Both brothers appeared to be interested in radical Islam and ethnic separatist movements in the Caucuses Mountains of Russia, bur what that has to do with the Boston Marathon is anyone’s guess.  He is hospitalized, sedated, and on a breathing machine.

The younger brother became a citizen of the US last fall.  And older brother Tamerlan Tsarnaev had petitioned to become a U.S. citizen, but the government put it on hold because the FBI had previously interviewed him at the request of the Russian government.  There was also a complaint, although no conviction, of domestic abuse.  Doctors say the 26-year old had so many bullet wounds from his gun battle with police, they can’t tell which one killed him.

Several hundred extra police officers will be monitoring the London Marathon, in case any copycat gets ideas.  They’ll have their hands full because hundreds of thousands of spectators usually line the route of the race.  Officials say the Marathon will begin with 30 seconds of silence to honor the victims of the Boston Bombing.

The Boston Bombers’ apparent link to Chechen separatism (despite being born in Kyrgyzstan) is reviving fears for security at the 2014 Winter Olympics in Sochi, Russia.  That’s only a few hundreds kilometers away from Chechnya, Dagestan, and all a bunch of angry, armed men.  Russia has vowed to make the games the “safest in history”.  And now, "tougher measures will be taken," said Valentin Balakhnichev, the head of the All-Russian Athletics Federation.

The EU is about to announce it is lifting economic sanction on Myanmar (Burma), as a reward for political and economic reforms not least of which saw the release of Nobel Prize Winner Aung San Suu Kyi’s release from house arrest and election to parliament.  The EU had barred investments and banned imports of the country's lucrative timber, metals and gems.

An avalanche killed five snowboarders in Colorado’s backcountry near Loveland Pass.  A sixth survived.  The main highway through that part of the Rocky Mountains is now blocked.

87-year old Giorgio Napolitano has been reelected to another 7-year term as President of Italy.  The largely ceremonial position has been made important because of the parliamentary impasse between Left, Right, and Anti-Establishment parties, the latter of which calls the move a “coup d’etat”.

The death toll from the massive earthquake in western China’s Sichuan Province has risen to 170 as more bodies are pulled from the wreckage.  The rescue effort is not easy: The quake knocked out roads and telephone lines, power and water supplies.

Japan is joining negotiations on the Trans-Pacific Partnership (TPP), New Zealand's Trade Minister Tim Groser says.  The TPP is the proposal for the world’s largest free trade agreement.  Several US labor and manufacturing oppose Japan’s inclusion and the whole TPP deal, having been burned on free trade deals before.  The existing TPP countries are Australia, New Zealand, Brunei, Canada, Chile, Malaysia, Mexico, Peru, Singapore, the United States and Vietnam.
