The Army reservist who opened fire in a bowling alley and then at a bar in Lewiston, Maine, killing 18 people, was found dead Friday from a self-inflicted gunshot, ending an intensive two-day search that had the state on edge.

Robert Card, a firearms instructor who grew up in the area, was found dead in nearby Lisbon Falls, Gov. Janet Mills said at a Friday night news conference.

"Like many people I’m breathing a sigh of relief tonight knowing that Robert Card is no longer a threat to anyone,” Mills said.

April Stevens, a Lewiston resident who knew one of the victims, said she was relieved to learn that the "monster and coward” who inflicted so much pain was no longer a danger.

"I’m relieved but not happy," she said. "There was too much death. Too many people were hurt. Relieved, yes, happy, no.”

Maine Department of Public Safety Commissioner Mike Sauschuck said Card was found at 7:45 p.m. near the Androscoggin River, about 8 miles (13 kilometers) southeast of where the second shooting occurred Wednesday evening. He declined to divulge the location but an official told The Associated Press the body was at a recycling center from which Card had been fired.

The official was not authorized to discuss details of the investigation publicly and spoke on condition of anonymity.

Mills said she had called President Joe Biden to alert him that Card was dead.

"Tonight we’re grateful that Lewiston and surrounding communities are safe after spending excruciating days hiding in their homes,” Biden said in a statement. He added that "Americans should not have to live like this” and called on Congress to take action on gun violence.

The deadliest shootings in Maine history stunned a state of 1.3 million people that has relatively little violent crime and had only 29 killings in all of 2022. In Lewiston, the 37,000 residents and those in surrounding communities were told to stay in their homes as hundreds of police officers, sheriff’s deputies, FBI agents and other law enforcement officials swarmed the area.

Card, 40, of Bowdoin, was a U.S. Army reservist. Leo Madden, who said he ran Maine Recycling Corp. for decades, told the media that Card worked there for a couple of years and nothing about him stood out. Madden said he didn’t remember when Card was employed or whether he was fired or quit.

Last summer, Card underwent a mental health evaluation after he began acting erratically during training, a US official told the media. A bulletin sent to police across the country shortly after the attack said Card had been committed to a mental health facility for two weeks after "hearing voices and threats to shoot up” a military base.

A U.S. official said Card was training with the Army Reserve’s 3rd Battalion, 304th Infantry Regiment in West Point, New York, when commanders became concerned about him. State police took Card to the Keller Army Community Hospital at West Point for evaluation, according to the official, who was not authorized to publicly discuss the information and spoke to the AP on condition of anonymity.

On Wednesday, Card attacked the bowling alley first, then went to the bar. Police were quickly sent to both locations but Card was able to escape. For the next two days authorities scoured the woods and hundreds of acres of Card's family-owned property, and sent dive teams with sonar to the bottom of the Androscoggin River.

Law enforcement officials had said they hadn't seen Card since his vehicle was left at a boat ramp Wednesday shortly after the shootings.

Hours before Card's body was found, the names and pictures of the 15 men, two women and 14-year-old boy who died in the shootings were released at a news conference.
