But still no official word on who is believed to have carried out the attackTwo days since the bombings at the Boston Marathon, more details have emerged. There were two bombs which exploded within 12 seconds of each other. Three people were killed, 183 people were injured. A broken pressure cooker was found near the site and may have been a part of the bomb. There has been no official statements as to who carried out the attacks, or even whether the attack was an act of domestic or foreign terrorism. CNN has the full story:
Within a day of the Oklahoma City bombing, officials had named their suspect: Timothy McVeigh. Within two days of the 9/11 attacks, investigators had zeroed in on al Qaeda as the perpetrator.
But as loved ones mourn the deaths of three people and dozens of others remain hospitalized from the dual bombings Monday near the finish line of the Boston Marathon, two questions continue to hound authorities: Who triggered the attack, and why?
On Wednesday morning, a federal law enforcement source with firsthand knowledge of the investigation told CNN that a lid to a pressure cooker thought to have been used in the bombings had been found on a roof of a building near the scene.
While such clues may move the investigation forward, they did not reveal whether the attack was an act of domestic or foreign terrorism.
