BOSTON (AP) — Investigators have their suspect and are now looking to stitch together the details of the Boston Marathon bombing plot.
FBI agents have picked through a landfill near the University of Massachusetts Dartmouth, where 19-year-old suspect, Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv), was a sophomore. FBI spokesman Jim Martin would not say what investigators were looking for.
Also, two college buddies of the suspect have been questioned, but a lawyer says they had nothing to do with the attacks. He says the two are being detained in a Boston jail for violating their student visas by not regularly attending classes.
And U.S. officials said his mother had been added to a federal terrorism database months before the April 15 attack. His mother said it's all "lies."
