A massive manhunt that shut down the Boston area has officially come to an end.
On Friday night, Police tracked 19-year-old Dzhokhar Tsarnaev to a home in the suburb of Watertown, MA, where he was cornered in a boat. The suspect had injuries that police are now describing as serious.
His brother, 26-year-old Tamerlan Tsarnaev, died in a shootout with police Thursday.
Monday's bombing at the marathon left three people dead and dozens of others injured.
