Dzhokhar Tsarnaev, 19, has been charged in a criminal complaint over the bombing of the Boston Marathon. He appeared before a federal magistrate who came to his bedside at Beth Israel Deaconess Medical Center. He nodded affirmatively in response to questions, but spoke only one word: "no," after the magistrate asked him if he could afford a lawyer. The New York Times has the transcript. After much controversy, it's good to see that he was read his Miranda Rights. [NYTimes.com] And here's the FBI affidavit. [chicagotribune.com] Read the rest

The New York Times has a beautiful interactive feature with audio narratives from "some of the people seen near the finish line." What is most striking about the interactive design: as you scroll down the page to listen to each story, you see where each person was in the still image from NBC's broadcast of the race. Powerful. Here's how the Times put it together. Read the rest

Responding to claims from the mother of the two Boston bombing suspects, the FBI said today it had not been tracking her oldest son, nor had the bureau spoken with him last week after the deadly marathon bombing. The only communication the FBI claims to have ever had with Tamerlan Tsarnaev "was an interview agents conducted with him in 2011 at the urging of a foreign government, since identified as Russia."

Below, an array of perspectives on what legal rights the 19-year-old American citizen suspected of co-executing the Boston Marathon bombings has, and whether law enforcement is obliged to honor those rights under the circumstances:

• "If captured, I hope [the] Administration will at least consider holding the Boston suspect as [an] enemy combatant for intelligence gathering purposes. If the Boston suspect has ties to overseas terror organizations he could be treasure trove of information. The last thing we may want to do is read Boston suspect Miranda Rights telling him to 'remain silent.'"—Republican senator Lindsay Graham, on Twitter.

• "There's no way an American citizen committing a domestic crime in the city of Boston could be tried as an enemy combatant. It could never happen. And that shows absolute ignorance of the law."—Alan Dershowitz, prominent defense attorney and Harvard law professor, speaking on CNN. Read the rest

C.J. Chivers, New York Times reporter and author of THE GUN, a social history of the AK-47, co-wrote this "primer on the land from which the Tsarnaev family hailed."

As the NYT piece notes, current Chechen leader Ramzan A. Kadyrov wrote on Instagram (!) that any ties between the Boston bombing suspects and Chechnya were mistaken: “The roots of this evil are to be found in America.” Read the rest

According to his friends, University of Massachusetts sophomore Dzhokhar Tsarnaev worked out, slept in his dowm room, and hung out with fellow students on the same day of the attack on the Boston Marathon, after the bombs went off. One student quoted in the Boston Globe who did not want to be identified said she saw Tsarnaev at a party on Wednesday night attended by some of his soccer team friends.

“He was just relaxed,” she said.

Depending on which acquaintance's quote you read, the 19-year-old either sounds normal or creepy:

Emily DeInnocentis, 23, said Tsarnaev stood out to her because of some odd behavior, like spreading messy string cheese all over her couch, and picking up her cat and carrying it upstairs for no reason.

“We just didn’t invite him over after that. How many people just pick up your cat and go upstairs?” she said.
