Relatives, friends, teachers, and students gathered last night to mourn the tragic death of Glen Wright, who was stabbed to death outside his grandmother's East Village building because gang members mistook him for someone else. (We noted this devastating story yesterday, and like many, we're still profoundly saddened.) Wright, who died at age 21, was taking a break from helping his grandmother wash windows at the Baruch Houses on the Lower East Side when a group of men approached him. Suspect Joel Herrera, 20, is accused of stabbing Wright repeatedly in the neck; he told detectives he confused Wright with someone who assaulted one of his friends. Cops are searching for the other assailants.
