THREE college friends of Boston Marathon bombing suspect Dzhokhar Tsarnaev have appeared in court, pleading not guilty to separate charges of lying to investigators and conspiring to obstruct justice.
Dias Kadyrbayev and Azamat Tazhayakov, both 19-year-olds from Kazakhstan, are charged with impeding the investigation into the April 15 attack that left three dead and about 200 injured by trying to conceal and cover-up evidence.
Robel Phillipos, 19, another college friend of Tsarnaev's, pleaded not guilty to charges that he lied to police after the attack.
In the wake of the Boston Marathon blasts, police carried out a massive manhunt for Tamerlan and Dzhokhar Tsarnaev, who allegedly planted two pressure-cooker bombs near the finish line.
