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.

Karen Diamond, 82, became the first death from the June 1 firebombing of a Boulder, Colorado, demonstration voicing support for Israeli hostages in Gaza.
