The Boston bomb marathon investigation has turned into a manhunt and reportedly police are surrounding a house that has Dzhokhar Tsarnaev and the standoff could last hours as authorities try to work on motive for the original attack.

On Thursday night the brothers murdered an MIT officer after robbing a store and after jacking a car they led the authorities on a chase through Boston suburbs that resulted in a firefight and left one of the suspects dead as the other escaped. All of Boston is on lockdown and the government is telling people to stay inside.

The manhunt turned so fierce around the city that the new David O. Russell film "American Hustle" cancelled filming in the city of Boston on Friday. The movie stars Jennifer Lawrence, Bradley Cooper, Christian Bale, Amy Adams, Robert De Niro, Jeremy Renner, and Louis C.K and involves the government working with con men to collaborate on the ABSCAM investigation.

The movie was filing in Worcester previously and was back in the city on Thursday and Friday. The brothers appear to have normal lives and one was an amateur boxer and had a scholarship from an area school, while the one that was still at large attended the same high school as Matt Damon and Ben Affleck.
