A suspect has been charged with two counts of first-degree murder after two Israeli embassy staffers, a couple who were about to become engaged, were gunned down Wednesday night outside of a Jewish museum in Washington,

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.
