When the ticket was found in police records during the hunt for the wounded bomber, it sparked an immediate FBI raid on the Boylston street address, which is the home of a friend, Maximilian Freddura, part of a prominent Boston restaurateur family.

Freddura’s apartment, where police officials say Dzhokhar was a frequent guest, is a block away from the corner of Laurel and Dexter Streets where police caught up with the Tsarnaev brothers five days after the marathon bombing.

After a chaotic exchange of gunfire that night that included the detonation of several explosives, the older Tsarnaev, Tamerlan, was killed, while his brother Dzkhokhar managed to escape, though injured. Dzkhokhar was captured hours later, hiding in a covered boat.

“Was he headed here? I don’t know,” Freddura told ABC News last week, referring to Dzhokhar. Freddura attended Cambridge Rindge and Latin, the same high school attended by both Tsarnaevs. “He certainly would not have been welcomed.”
