Police have arrested a suspect in the Boston Marathon bombing.
Law enforcement officials told CNN that authorities have confirmed the man in custody is 19-year-old Dzhokar Tsarnaev, who escaped an overnight shootout with police that left his older brother Tamerlan Tsarnaev — the other man wanted in the bombings — dead.
The younger Tsarnaev was in need of undisclosed medical care, the officials said. . .
