The shelter-in-place order has been rescinded, but hunting has been banned in the cities of Lewiston, Lisbon, Bowdoin and Monmouth, officials said.

Residents are urged to remain vigilant.

Authorities said they do not know how many weapons suspect Robert Card may have.

A 14-year-old boy and his father and a 76-year-old man and his wife were among the 18 victims killed in Wednesday's mass shooting at a bowling alley and bar, Maine officials said.

Officials released the 18 names at a news conference on Friday before holding a moment of silence.

Four of the 18 victims were deaf, officials said.

Though fear is still gripping Lewiston, Maine, some residents are emerging from the shelter-in-place order to grieve and to lift up their community.

"People mourn in different ways … for me, I want to be here doing something in my community, trying to uplift everybody," resident Alex McMahon told ABC News after he hung up a "Lewiston Strong" sign near the bowling alley.

McMahon said he knows one of the 18 people killed in Wednesday's mass shooting.

"A lot of people knew people that were affected," he said. "One of our regular customers was one of the men that died a hero trying to take out the gunman."

He said he wants to help the community heal, adding, "We want to heal with unity and strength.”

President Joe Biden was briefed Friday afternoon on the latest information surrounding the Maine mass shooting investigation and manhunt, according to the White House.

Over 200 FBI personnel are in Maine to help the victims and contribute to the search, FBI Director Christopher Wray told Biden.

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?"
