WASHINGTON (AP) — The Obama administration has a range of legal options in the Boston Marathon bombings, and they could include seeking the death penalty against the 19-year-old suspect in the case.

The administration has indicated it intends to move quickly to build a criminal case against Dzhokhar Tsarnaev. But investigators plan to first question him without informing him of his legal rights to remain silent and have an attorney present.

Several Republican lawmakers on Saturday criticized the administration’s approach because they said it would afford Tsarnaev more rights than he deserves. The federal public defender for Massachusetts called for the quick appointment of a lawyer to represent Tsarnaev because of serious issues involving his interrogation in the absence of a lawyer.

Prosecution of Tsarnaev in federal court would seem a natural course for an administration that previously won a life sentence against Umar Farouk Abdulmutallab of Nigeria for trying to blow up a packed jetliner using a bomb sewn into his underwear on Christmas Day 2009.

As a U.S. citizen, Tsarnaev could not be tried by a military commission under current law; the only option for prosecuting an American is in civilian courts.
