" In a criminal complaint unsealed Monday in United States District Court for the District of Massachusetts, Mr. Tsarnaev was charged with one count of "using and conspiring to use a weapon of mass destruction" against persons and property within the United States resulting in death, and one count of "malicious destruction of property by means of an explosive device resulting in death" in last week's bombings.

If he is convicted of the charges, he could face the death penalty."
