CBS LAS VEGAS-Three additional suspects were arrested Wednesday in the Boston Marathon bombings investigation. All three were friends of Dzhokhar Tsarnaev and attended UMass-Dartmouth with him. The charges are related to incidents after the bombings and interfering with investigators. Do you think the conspiracy behind the Boston Marathon Bombings goes beyond the two Tsarneav brothers? Dick Feeney, Producer of The Rat Pack Is Back, talks about the show that is playing at the Rio Casino.
