Hundreds of police fanned out across the state of Maine hunting for a man wanted in connection with mass shootings at a bar and a bowling alley in the town of Lewiston, as news outlets reported a death toll ranging from 16 to 22, with dozens more wounded.
Officials said there were multiple casualties in the shootings on Wednesday but declined to provide figures.
State and local police identified Robert R. Card, 40, who reportedly had been committed to a mental health facility over the summer, as a person of interest in the case. Earlier, they posted on Facebook photographs of a bearded man in a brown hoodie and jeans at one of the crime scenes, holding what appeared to be a semi-automatic rifle in the firing position.
"We have literally hundreds of police officers working around the state of Maine to investigate this case to locate Mr. Card, who is a person of interest," Maine Public Safety Commissioner Mike Sauschuck told a news conference.
Police found a white SUV they believe Card drove to the town of Lisbon, about 7 miles (11 km) to the southeast, and Sauschuck said people were asked to remain indoors in both Lewiston and Lisbon.
Several media reported that a Maine law enforcement bulletin identified Card as a trained firearms instructor and member of the U.S. Army reserve who recently reported that he had mental health issues, including hearing voices. It also said he threatened to shoot up a National Guard base.
"Card was also reported to have been committed to mental health facility for two weeks during summer 2023 and subsequently released," said the notice from the Maine Information & Analysis Center.
Reuters could not authenticate the bulletin. The Associated Press reported it was circulated to law enforcement officials.
The army did not immediately respond to requests for information about Card, including details on his service record.
