Domestic briefs: Friends of suspected Boston Marathon bomber indicted Two college friends of suspected Boston Marathon bomber Dzhokhar Tsarnaev were indicted Thursday for allegedly trying to thwart investigators by throwing away fireworks and other items they found in Tsarnaev's dorm room the day before his capture. Dias Kadyrbayev and Azamat Tazhayakov, both 19 and nationals of Kazakhstan, face charges of conspiracy to obstruct justice. The two, who were in the United States attending college and shared an apartment in New Bedford, have been detained since they were charged in a criminal complaint in May. If convicted, they face up to 20 years in prison. Both are scheduled for arraignment Tuesday. Tsarnaev, 20, is accused in the April 15 blasts at the Boston Marathon that killed three people and injured more than 260. New Jersey Chris Christie signs gun control bills New Jersey Gov. Chris Christie, a likely Republican contender for the White House in 2016, on Thursday signed into law 10 bills tightening restrictions on guns in the state. The measures included banning the purchase of handguns by people on a federal watch list of potential terrorism suspects and stepping up penalties on some firearms violations. The moves made New Jersey the latest northeastern state to tighten gun laws in the wake of a December massacre at an elementary school in Newtown, Conn., that left 26 people dead and sparked a renewed debate on gun control. In a nod to public pressure from gun-rights activists, Christie held off on signing other proposed measures that would have banned .50-caliber rifles, required dealers to log ammunition sales and allowed for instant background checks. Man who posted online about killing wife turns himself in: A South Florida man who authorities say fatally shot his wife - and apparently then posted a photo of her body on Facebook - has turned himself in to police. Miami-Dade police reported that Derek Medina, 31, turned himself in Thursday, telling them he had shot Jennifer Alfonso, 26. A post on a Facebook page identified as Medina's says: "I'm going to prison or death sentence for killing my wife." The next post was a photograph showing a woman in a black leotard, slumped on the floor with blood on her left arm and left cheek. Former Senate majority leader hospitalized: Former U.S. Senate Majority Leader Trent Lott (R-Miss.) was hospitalized in Jackson, Miss., on Thursday. A Baptist Medical Center spokesman said Lott, 71, was listed in fair condition but would not say why Lott was hospitalized. Lott stepped down as Senate majority leader in 2002 after he made remarks at a birthday party for then-Sen. Strom Thurmond (R-S.C.) that seemed to support segregation. He returned to the Senate leadership as minority whip before retiring in 2007.
