Some more from the WSJ:
Authorities captured a 19-year-old college student suspected in the deadly Boston Marathon bombings after one of the biggest manhunts in U.S. history paralyzed an entire metropolis.
Police and Federal Bureau of Investigation agents converged on a house in the Boston suburb of Watertown late Friday, and apprehended Dzhokhar Tsarnaev, one of two brothers alleged to have exploded two homemade bombs in downtown Boston, killing three people and injuring more than 175. Images of the suspect were shown all day on national TV and online and online.
Authorities halted public transportation, closed schools and advised residents to stay locked indoors for much of Friday during the manhunt.
Mr. Tsarnaev had escaped capture after leaving behind his older brother, 26-year-old Tamerlan Tsarnaev, who was killed in a firefight with police early Friday. The brothers, carrying an arsenal of explosives, fired guns and threw pipe bombs in the fight after an overnight crime spree that left dead an officer of the Massachusetts Institute of Technology, authorities said. The Federal Bureau of Investigation had interviewed Tamerlan Tsarnaev in 2011 at the request of the Russian government, but it found no suspicious evidence and closed the matter, a U.S. official said.
