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.

At least 16 people are believed to be dead, though that number is in flux, and dozens more have been injured after a bowling alley came under fire in Lewiston, Maine, Wednesday evening -- the deadliest shooting of the year and one of the deadliest in recent decades.

Riley Dumont said she heard a loud bang after which her father, a retired cop, corralled them into a corner and put protection in front of them including "tables and a big bench that the kids were hiding behind."

“I was laying on top of my daughter. My mother was laying on top of me,” said Dumont. "It felt like it lasted a lifetime," she added. "I just remember people sobbing and crying."

Another witness at the bowling alley, whose name is Brandon, but whose last name was not made available, described hearing a "loud pop."

"Thought it was a balloon," Brandon said. "I had my back turned to the door. As soon as I turned and saw that it was not a balloon, he was holding a weapon. I just bucked it down the lane and I slid basically into where the pins are and climbed up to the machine and was on top of the machines for about 10 minutes until the cops got there."

Meghan Hutchinson, another shooting witness, said, "We were very scared and we didn't know, like, we didn't know what to do, what to expect from this. You know, nothing like this has ever happened here before. We barricaded in there and another parent was in the room with me. She had a phone and she called 911."

Zoe Levesque, 10, was grazed by a bullet.

“I never thought I'd grow up and get a bullet in my leg," said Levesque. "Like, why do people do this? I was more worried about, like, am I going to live and going to make it out of here? Like, what's going to happen? Are the cops going to come?"
