Attorney General Merrick Garland thanked law enforcement for their efforts in finding the suspect and pledged continued support for those who have been impacted by the mass shooting.

"I want to thank our state and local law enforcement partners, along with the FBI, ATF, U.S. Marshals, and other federal agencies who have been working day and night to locate the shooter and keep the affected communities safe," Garland said in a statement.

Garland said that the FBI would continue to provide victim support resources to those who have been devastated by the tragedy that happened in Lewiston on Wednesday.

"No community should have to endure these mass shootings which have become routine in our country," Garland said.

Lewiston Police Chief David L. St. Pierre said authorities are relieved that the manhunt for mass shooting suspect Robert Card has ended.

"Our community can now breathe a sigh of relief, as the Gov. stated, and I can’t echo that enough," the police chief said, addressing the media at a news conference Friday night.

Despite Carr being found dead of an apparent self-inflicted gunshot wound, which authorities confirmed at the press event, St. Pierre said law enforcement has a lot of work ahead of them.

"Our work again is not done here. I was very elated tonight when I got the call from Commissioner Sauschuck advising me of the revelation of what took place and that Mr. Card is deceased and no longer a threat to our community or any other community," he said. "I just don’t want to forget the families that are grieving and will continue to grieve. I don't want to forget the law enforcement officials that have worked tirelessly throughout this whole event to come to a good conclusion."

He added, "I'm very happy to be here, and I’m very happy to say the threat is over."

Authorities also noted that hunting, which had been restricted in four communities where searching for the suspect had been taking place, is no longer banned for the weekend.

Officials said they will share further updates on Saturday.

Gov. Janet Mills officially confirmed the Maine mass shooting suspect Robert Card is dead. Authorities found his body on Friday, she said.

Maine shooting suspect Robert Card has been found dead of a self-inflicted gunshot wound, multiple law enforcement sources told ABC News.

A body has been recovered, the sources said.

The body was found at a recycling center in Lisbon where Card worked, sources said.

The Lewiston Police Department has issued a shelter-in-place order for the city. Residents are urged to stay inside with their doors locked.

The FBI is sending in aviation units to help in the search for the gunman. New Hampshire police are putting up roadblocks to try to confine the gunman if he’s on the run.

Maine Gov. Janet Mills said in a statement, "I am aware of and have been briefed on the active shooter situation in Lewiston. I urge all people in the area to follow the direction of State and local enforcement."

New Hampshire Gov. Chris Sununu said New Hampshire "officials have been in touch with our counterparts in Maine to offer and provide any medical and safety resources needed as they manage this horrific situation. Our hearts and prayers are with the people of Maine."

President Joe Biden spoke on the phone with Gov. Mills, Maine Sens. Angus King and Susan Collins and Rep. Jared Golden, D-Maine, and "offered full federal support in the wake of this horrific attack," according to the White House.
