Homeless twins injured in fight outside Arlington library Two homeless men sleeping outside Arlington Central Library were attacked early Monday by a man in his late 20s who police said may be another homeless man known to the victims. The two victims, 26-year-old twins, were hospitalized with serious but not life-threatening lacerations on their torsos and faces, police said. Arlington police spokesman Dustin Sternbeck said the three men engaged in a dispute around 3 a.m. on Monday that escalated into a fight, in which the man attacked the twins with a blunt force object. Sternbeck said the twins, who remain hospitalized, are working with police to identify their attacker in photographs. "We have a good idea" of his identity, Sternbeck said.
