Law enforcement authorities in Maine are in the midst of a sprawling manhunt Thursday for the gunman who killed 18 people in separate shootings at a bowling alley and a restaurant in the state’s second-largest city.

An additional 13 people were injured in the rampage that police said suspect Robert Card unleashed Wednesday evening in Lewiston.

The suspect’s vehicle was found abandoned in Lisbon later that night, just eight miles southeast of Lewiston.

Mr. Card remains at large and is considered armed and dangerous.

Maine State Police are leading the investigation, with assistance from Lewiston police and the FBI and ATF field offices in Boston.

“This city did not observe this terrible assault on its citizens, on its peace of mind, on its sense of security,” Gov. Janet Mills said at a Thursday press conference. “No words can truly, fully measure the grief.”

Mr. Card, 40, is a firearms instructor and a sergeant in the Army Reserve, according to Army records provided to CNN.

He first joined the Army Reserves in 2002 and works as a petroleum supply specialist at a training facility in Saco, Maine.

Mr. Card was committed to a mental health facility for two weeks over the summer where the suspect had reported “hearing voices and threats to shoot up” the military base.

It’s unknown what condition caused him to seek medical care.

Shelter-in-place orders remain in effect for Lewiston and Lisbon as well as the nearby towns of Auburn and Bowdoin following the mass shooting.

A gunman armed with a long rifle first targeted Just In Time Recreation (formerly known as Sparetime) bowling alley just before 7 p.m. Wednesday.

Maine State Police Colonel William Ross said seven people were killed at the bowling alley, with the victims identified as one woman and six men.

Col. Ross said that eight more people were killed at Schemengees Bar and Grille roughly 10 minutes later.

Authorities said all eight victims were men, with seven killed inside the establishment and one person killed outside.

Police said that three people who suffered gunshot wounds during the carnage later succumbed to their injuries, bringing the death toll up to 18.

Mr. Card is facing eight counts of murder for the eight victims police have identified so far.

Col. Ross said he expects that number to increase as the investigation continues.

Police did not disclose the ages of those slain by the gunman during the Thursday morning press conference.

Multiple families and children were at Just In Time when the carnage broke out.

Ten-year-old Zoey Levesque was grazed by a bullet at the bowling alley once the shooter opened fire on the patrons.

“I never thought I’d grow up and get a bullet in my leg,” Zoey told ABC News on Wednesday night. ‘Like, why do people do this?

“I was more worried about, like, am I going to live? Am I going to make it out of here,” Zoey continued. “Like, what’s going to happen? Are the cops going to come?”

Leroy Walker, whose son runs Schemengees, said police informed him on Thursday that his child was one of those killed in the shooting.

The father had a hunch about his son’s fate when he spoke with NBC Boston prior to getting police confirmation.

‘I know it as well as I know I’m standing here telling you because he’s not here and he’s not at any other hospital and he’s not running the streets or he would have called us, because he manages Schemengees, so I know he was there,’ Mr. Walker told the station.

The active search for the shooter has left ripple effects throughout Maine.

The state’s largest city, Portland — which is nearly 40 miles south of Lewiston — closed its public schools Thursday while the suspect is still on the loose.

Outdoor goods retailer L.L. Bean shut down its headquarters, flagship store and factories in Maine in light of the manhunt as well.

President Biden said he gave his administration the greenlight to provide Maine authorities with anything they need as police continue to look for Mr. Card.

He also prodded congressional Republicans about helping pass a ban on “assault weapons.”

“I urge Republican lawmakers in Congress to fulfill their duty to protect the American people. Work with us to pass a bill banning assault weapons and high-capacity magazines, to enact universal background checks, to require safe storage of guns, and end immunity from liability for gun manufacturers,” Mr. Biden said.

“This is the very least we owe every American who will now bear the scars — physical and mental — of this latest attack,” he continued.
