The Army Reserve and a Maine sheriff’s department were aware of a reservist’s deteriorating mental health more than five months before he killed 18 people in Lewiston, Maine, according to records released on Monday. Just six weeks ago, the records show, he had grown increasingly paranoid, punched a friend and said he was going to carry out a shooting spree.
But there is no indication in the documents that any law enforcement officials ever made contact with the reservist, Robert R. Card II, 40, who carried out the deadliest mass shooting in America this year and set off a two-day manhunt before he was found dead.
The warnings about Mr. Card were far more explicit than Maine officials had publicly acknowledged in the days since the shooting on Oct. 25. They came from Mr. Card’s family members — who believed he was hearing voices — and his Army Reserve unit in Saco, Maine, and were investigated by the Sheriff’s Office in Sagadahoc County, where Mr. Card lived.
Mr. Card’s family told a sheriff’s deputy in May that Mr. Card had become angry and paranoid starting early this year. In particular, he had begun to claim — wrongly, the family said — that people were accusing him of being a pedophile.
When the deputy, Chad Carleton, reached out to Mr. Card’s base in Saco, he learned that people there already had “considerable concern” for Mr. Card’s mental health, according to a report that the deputy wrote.
Two months later, in July, Mr. Card was treated at a psychiatric hospital in New York for two weeks, according to a later report, after an incident at the U.S. Military Academy in West Point. He had accused “several other soldiers” of calling him a pedophile, shoved one and made veiled threats that he would “take care” of things, the report said.
He made far more explicit threats in mid-September, telling a friend that he had guns and was “going to shoot up the drill center at Saco and other places,” according to a Sheriff’s Office report from that month.
In response to that episode, the Army Reserve contacted the Sheriff’s Office, which assigned a sergeant, Aaron Skolfield, to check on Mr. Card at his home in Bowdoin, Maine.
Sergeant Skolfield went to Mr. Card’s home on Sept. 16 and tried to make contact with him, but no one came to the door, despite the sergeant hearing someone he thought might be Mr. Card moving around inside.
The sergeant said in his report that soon after, he spoke with Mr. Card’s commanding officer, Capt. Jeremy Reamy, who said that he thought it was best for Mr. Card to “have time to himself for a bit.” Captain Reamy also said that the Reserve was working to get Mr. Card to retire and receive mental health treatment. He declined to comment on Monday.
The Army Reserve said in a statement that it had reached out to the Sheriff’s Office regarding Mr. Card “out of an abundance of caution after the unit became concerned for his safety.”
Sergeant Skolfield said he had also contacted Mr. Card’s brother, Ryan Card, who said that he and his father would try to take his brother’s guns away. The sergeant said he had urged Ryan Card to contact the sheriff’s department if he felt that his brother needed “an evaluation.” Ryan Card did not immediately respond to a request for comment.
Sheriff Joel Merry of Sagadahoc County said in a statement that he believed his deputies had acted appropriately, but he added that his department would evaluate its procedures for wellness checks.
Sergeant Skolfield declined to comment over the weekend when a reporter contacted him by phone.
Earlier on Monday, Gov. Janet Mills declined to answer questions about law enforcement’s prior interactions with Mr. Card. The state’s public safety commissioner, Michael J. Sauschuck, mentioned only a drunken driving incident in 2007 when asked on Saturday about previous contact with law enforcement.
The record of Mr. Card’s previous run-ins with reservists and warnings to the sheriff’s department are the latest to raise questions about whether more could have been done to prevent the Maine shooting or keep Mr. Card from buying guns.
The reports do not make clear whether Mr. Card was committed to the hospital in July involuntarily, but if he had been, he may have been barred from possessing guns. One report describes Mr. Card’s Reserve colleagues hearing him complain about the unit commanders having him committed and saying they are “the reason he can’t buy guns anymore.”
Federal officials have said that Mr. Card legally bought some guns just days before the shooting. The F.B.I. said there was nothing to prevent him from legally purchasing weapons.
Mr. Card began his rampage at a bowling alley last Wednesday evening, where he killed seven people. He then drove to a bar and opened fire again, shooting people who were playing pool and several deaf friends competing in games of cornhole. Eight people died at the bar, and three more at the hospital.
Thirteen more people were wounded between the two scenes. Mr. Card fled and was found dead two days later, having shot himself in a trailer at a recycling plant where he used to work.
In May, Mr. Carleton, the sheriff’s deputy, met with Mr. Card’s former wife and 18-year-old son at a high school where they had raised concerns with a police officer assigned to the school. Mr. Card’s son relayed that his father had recently grown very angry with him and accused him of talking behind his back.
The son and his mother told the deputy that they were worried about Mr. Card’s deteriorating mental health and rising paranoia. Mr. Card’s former wife told the deputy that he had recently collected 10 to 15 handguns and rifles from his brother’s home and brought them back to his own house.
That night, Mr. Card’s ex-wife visited him with his sister, Nicole, and later reported that he had opened the door with a gun and complained that there were people outside his home, casing it. But she told the deputy the next day that Mr. Card had also agreed to see a doctor about his paranoia and hearing voices. It is unclear whether he did so.
Mr. Carleton wrote that Mr. Card’s brother said his paranoia had started around the time that Mr. Card got hearing aids, earlier this year. Mr. Card’s sister-in-law told The New York Times last week that he had gotten them because his hearing had deteriorated after two decades in the Reserve.
When the sheriff’s department was contacted by the Reserve in September, Sergeant Skolfield wrote that he was assured by Mr. Card’s brother that he would work with their father to make sure Mr. Card did not have any access to guns.
“They have a way to secure his weapons,” the sergeant wrote in the last line of his report.
