Now, some facts have been nailed down. One suspect has been killed and another hospitalized under the custody of authorities. Yet important issues continue to be clouded by mystery.

The surviving suspect, Dzhokhar Tsamaeva, has been confirmed as receiving treatment in custody at Beth Israel Deaconess Medical Center. CBS reports that his injuries include gunshot wounds on his neck and leg.

Questions regarding Dzhokhar's prosecution loom large. The unusual nature of his capture and alleged crime has been cited by law enforcement officials as justification for departing from standard arrest procedure. While due process typically requires Miranda Rights to be read to all suspects immediately upon their arrest, the statement of these rights has been stayed as per a decision made by the Department of Justice. (Slate) 

U.S. Attorney for Massachusetts Carmen Ortiz spoke as a representative of the Department of Justice on Friday. She said that the delay was permissible because of the suspect’s status as a national security risk.

The brothers moved to Boston in 2002. As President Obama noted, an explanation for the Tsamaeva brothers orchestrating this alleged act of terrorism has not been put forth at this time. Nor has any official word been released yet as to the likelihood of prosecuting other individuals for involvement in the explosion of bombs on the day of the Boston Marathon.

This and other critical information may be parlayed by investigators in the days and weeks to come. Or these questions, including why the bombings occurred and if other individuals were involved in carrying out an attack, may remain obfuscated irrevocably.
