Martin Richard, an 8-year-old boy was killed on Monday at the end of the Boston Marathon. The mother and sister were both critically injured in the blast. Martin's mother underwent brain surgery Monday night and his sister, 6, lost a leg in the blast. The status of his father, Williams, has not been released publicly.
Boston Police Commissioner Ed David said that there is not anyone in custody for the dual bombings at the Boston Marathon. Officials made a public plea to turn over any photographic or digital evidence they have from the scene.
The two explosions in Boston drew a swift response from the New York Police Department, as they began to mobilize their anti-terror units, bomb squads and additional uniformed presence to key New York City landmarks and buildings.
Members of Congress strongly suggested on Monday that the deadly Boston Marathon explosions were acts of terrorism.
