(CNN) -- New developments:
-- In all, 176 people were treated at area hospitals after the blasts with 17 in critical condition, Police Commissioner Ed Davis told reporters on Tuesday.
-- No one is in custody, Davis said.
-- Authorities are processing "the most complex crime scene that we have dealt with in the history of our department," Davis said.
-- Two explosive ordnance disposal sweeps were carried out Monday, the first early in the morning and the second an hour before the first runners crossed the finish line, Davis said. "They did not turn up any evidence," he said.
-- "Make no mistake: An act of cowardice and of this severity cannot be justified or explained," District Attorney Dan Conley said. "It can only be answered."
-- Thirty forensic specialists and a number of dogs trained to detect explosive devices and their residue are at the scene of the blasts, according to Gene Marquez, special agent in charge for the Bureau of Alcohol, Tobacco, Firearms and Explosives.
-- No unexploded devices have been found, Marquez said.
-- Authorities are asking those who may have video or pictures from the scene around the time of the blasts to call city or FBI hotlines.
-- The blast site will take several days to process, Marquez said.
-- FBI Agent Rick DesLauriers said law enforcement has received a "voluminous" number of tips.
-- Attorney General Eric Holder and FBI Director Robert Mueller arrived Tuesday at the White House.
Previously reported:
Three people died and scores more were wounded in the two bomb blasts, 12 seconds apart, that erupted near the finish line of Monday's Boston Marathon, Boston police said.
At least eight of the wounded are children.
Investigation:
-- A law enforcement official said there was no specific suspect in the bombings and no leading theory on a motive.
-- The official said investigators have found no surveillance video showing the bombs being put in place but were continuing to comb through video from nearby businesses, etc.
-- The intelligence community is poring through all threat reporting to see if there is anything that could be connected to the explosions in Boston, U.S. counterterrorism officials said.
-- The federal Emergency Response Team has cleared the crime scene near the finish line and is beginning to inventory the evidence, a federal law enforcement source said.
-- The device may have been placed in a trash can, from which shrapnel was created when it detonated.
-- Authorities searched an apartment late Monday in the town of Revere, northeast of Boston, and removed items, but would not say how the search might be linked to the investigation.
-- The official said the Revere search is connected to a young Saudi man on a student visa who has been questioned at a hospital.
-- The initial search found nothing related to the bombing, the official said.
-- The search took place with consent, so no search warrant was needed, a federal law enforcement official told CNN.
-- U.S. and Saudi officials said more than one Saudi has been interviewed. CNN knows of a male, whose apartment was searched, and a female. All those interviewed are cooperating, and none has been labeled a suspect, Saudi officials, said.
-- Investigators have urged police to be on the lookout for a "darker-skinned or black male" with a possible foreign accent in connection with Monday's bombings, according to a law enforcement advisory obtained by CNN. The man, seen with a black backpack and sweatshirt, was trying to enter a restricted area about five minutes before the first explosion, the notice says.
-- The FBI has taken over the investigation's lead role, said Richard DesLauriers, the special agent in charge of the bureau's Boston office.
-- "The situation remains fluid, and it remains too early to establish the cause and motivation," the FBI's Boston Division said in a statement asking people to call in with any information, images or details related to the explosions.
-- President Barack Obama on Monday ordered the "full resources" of the federal government to respond to the bombings, and called for increased security around the United States as necessary.
-- The Pakistani Taliban was not involved in the attack, spokesman Ihsanullah Ihsan said.
-- Federal law enforcement has been placed on "Level 1 mobilization," U.S. government sources said. "That's equivalent to all hands on deck," one official said. A senior federal official told CNN that teams were on standby to search flights leaving the United States; no team had been activated.
The devices:
-- A law enforcement official said the only devices recovered are the two that blew up, and no unexploded devices have been found. This account differs from others. The official said investigators have not determined how the two bombs were detonated. The official did not know whether the bombs contained ball bearings or other shrapnel.
-- One unexploded device was found at a hotel on Boylston Street near the bomb site and another unexploded device was found at an undisclosed location, said Rep. Bill Keating, D-Massachusetts. Keating, a member of the House Homeland Security Committee, called Monday's incident a "sophisticated, coordinated, planned attack."
-- But a law enforcement official said no unexploded device had been found.
