Second Suspect Captured

Some early details:

Dzhokhar A. Tsarnaev, 19, of Cambridge was apprehended shortly before 8:45 p.m. “They got him. He’s in custody,” a state trooper told the media gathered in the neighborhood. A crowd of onlookers broke into applause. Tsarnaev had been hiding in a boat in the backyard of a home in Watertown, just outside the city. He was rushed to a local hospital. Police had approached him cautiously, worried that he might be wearing a suicide bomb vest. “We got him,” Boston Mayor Thomas M. Menino tweeted immediately aftewards. He took to the police radio to thank officers personally, telling them, “Good job, guys!”

UPDATE: The Boston Police and Massachusetts Gov. Deval Patrick have held a press conference.
