Rodriguez’s charges were laid out in a criminal complaint. He was informed by U.S. Magistrate Judge Matthew Sharbaugh during an initial appearance in federal court Thursday that some of the charges against him carry the possibility of the death penalty or life in prison, officials said in the briefing later that afternoon.

Rodriguez reportedly gave himself up after two Israeli embassy employees, Yaron Lischinsky and Sarah Milgrim, were shot and killed in Washington D.C.
