A short video released by the FBI on Thursday shows two suspects in Monday's Boston Marathon attack walking single file on a sidewalk along the race route.
The video was released Thursday as investigators asked for the public's help in identifying the two men.
One of the two suspects in the Boston Marathon bombings left a bag believed to contain one of the explosives outside the Forum restaurant on Boylston Street in the city, FBI Special Agent in Charge Richard DesLauriers said. The bag was dropped there "within minutes" of the explosions, he added.FULL STORY
The FBI said Thursday it confirmed the presence of the deadly poison ricin in letters sent to a U.S. senator and President Barack Obama. A suspect has been arrested in the case.
That suspect appeared Thursday in federal court in Oxford Mississippi.
During a four-minute hearing, Magistrate Judge S. Allan Alexander ordered Paul Kevin Curtis - who appeared in court with attorney Christi McCoy - to remain in custody until a grand jury issues an expected indictment and a preliminary and detention hearing on April 29.
Earlier Thursday, the 45-year-old resident of Corinth, Mississippi, was charged with sending a threat to the president.
A criminal complaint charged Curtis with "knowingly depositing for conveyance in the mail and for delivery from any post office any letter, paper, writing or document containing threats to take the life of or to inflict bodily harm upon the President of the United States."
The federal complaint further charges him with sending "communications addressed to other persons, and containing a threat to injure the person of others."FULL STORY
