Now that police have secured the second of two suspects in Monday’s Boston Marathon bombing — who as of Saturday night lay hospitalized in serious condition under heavy guard and apparently in no shape to be interrogated — the long and meticulous process of examining motives, methods and possible links begins.

There was no immediate word on when Tsarnaev might be charged and what those charges would be. The twin bombings killed three people and wounded more than 180.

The most serious charge available to federal prosecutors would be the use of a weapon of mass destruction to kill people, which carries a possible death sentence. Massachusetts does not have the death penalty.

A Justice Department official said Friday the government is invoking a seldom-used public safety exception permitting officials to engage in a limited and focused unwarned interrogation of a suspect — in this case Dzhokhar Tsarnaev — without first reading him his typically assured Miranda rights. That official, as well as a second, both of whom spoke on the condition of anonymity, says Tsarnaev will be questioned by a special interrogation team for high-value suspects.

The public safety exception not only permits the unwarned questioning of a suspect, but also allows the government to introduce any statement yielded by such interrogation as evidence in court. The exception is triggered when authorities have an objectively reasonable need to protect themselves or the public from a clear and present danger.

However, the exception lasts only 48 hours and should be extended by declaring Tsarnaev a potential enemy combatant, under the Law of War, Republican Sens. Lindsey Graham, South Carolina; John McCain, Arizona; and Kelly Ayotte, New Hampshire, said in a statement Saturday. They were joined by New York Republican Rep. Peter King.

According to media accounts, Tsarnaev and his brother, Tamerlan, were Muslims who recently gravitated to a radical strain of Islam, going so far as to post Anti-American, jihadist videos on social-media sites. Both are thought to have as-yet-unprobed ties to a radical Muslim cleric hellbent on the destruction of the American way of life.

A day-long dragnet for Tsarnaev ended Friday, with police capturing the suspect covered in blood and hiding in a boat in the backyard of a man who called 911 after becoming suspicious of activity on his property.

“We got him,” Boston Mayor Tom Menino tweeted moments later, as neighbors gathered to form a gauntlet of cheers while a phalanx of police cars departed the scene.

Police moved in on Dzhokhar Tsarnaev Friday evening after a tip led them to the home on Franklin Street, where he apparently had been hiding in the back yard.

Neighbors said they heard more than 30 shots likened to “a roll of firecrackers shooting off.” Police swarmed the scene, and several explosions, possibly police concussion grenades, were heard after a robot moved in on the boat. Less than two hours later, at about 9 p.m., the suspect, believed to have been injured in a wild shootout that spanned Thursday night to Friday morning, was being taken to
