The death of Karen Diamond, 82, has turned the attack in Boulder, Colo., on marchers for Israeli hostages into a possible death-penalty case.

The suspect in the firebombing attack, Mohamed Sabry Soliman, will now face two counts of murder as a result of Diamond’s death.

Mohamed Sabry Soliman, the 46-year-old Egyptian national who allegedly threw two Molotov cocktails at the crowd of people raising awareness for Israeli hostages being held in Gaza, now faces first-degree murder charges in state court. He also faces attempted murder charges and a number of hate crime charges in federal court. He remains in custody.
