Federal authorities have reported the first major break in the search for suspects behind the Boston Marathon bombing, saying they now have security videos of one or two people they believe may have planted the explosives. An image has reportedly been captured of at least one suspect carrying — and perhaps dropping — a black bag at the site of the second bombing along the marathon route. The videos also show a number of people whom authorities want to question. Confusion reigned Wednesday when CNN and the Associated Press falsely reported the FBI had actually arrested a suspect. In response, the FBI released a scathing statement cautioning journalists not to jump to conclusions.
