Boston bombing suspect Dzhokhar Tsarnaev was discovered after a day-long manhunt by a homeowner - and not by authorities - because law enforcement officials had skipped over the street where he was hiding during their intensive search. Police did not search the area of Franklin Street where a Watertown man found Tsarnaev hiding in his boat - even though the neighborhood was part of a 20-block area that was supposed to be the focal point of the search, Bloomberg News is reporting based on interviews with 11 residents of the area.
