BOULDER, Colorado: For the 611 days since Omri Miran was taken hostage by Hamas, his family has lived in fear, his brother-in-law told those gathered at the Boulder Jewish Festival on Sunday, one week after a man firebombed a group calling for the release of Israeli hostages at the mall where Moshe Lavi now spoke.

“We received only partial, limited and at times horrifying proof of life,” Lavi said to a hushed crowd. “We don’t know how much he’s suffering, deprived of food, water, sunlight, tortured, abused, as I speak to you now.”

For its 30th year, the Jewish cultural festival centered on the stories of Israeli hostages after authorities said man who yelled “Free Palestine” threw Molotov cocktails at Boulder demonstrators calling for their release. Festival organizers said they reimagined it to focus on healing and center the group’s cause — raising awareness of the 55 people believed to still be in captivity in Gaza.

Authorities said 15 people and a dog were victims of the attack at the Pearl Street pedestrian mall. They include eight women and seven men, ranging in age from 25 to 88. One is a Holocaust survivor.

Not all were physically injured, and some are considered victims for the legal case because they were present and could potentially have been hurt.
