The authorities in Maine said an arrest warrant citing eight counts of murder had been issued for Robert R. Card, the 40-year-old man they were seeking in connection with the shootings Wednesday night at a bowling alley and bar in Lewiston.
But officials declined to say much about him at a news conference Thursday morning, other than that his location remained unknown and he should be considered armed and dangerous.
“We believe this is someone that should not be approached,” Col. William G. Ross of the Maine State Police said, urging the state’s residents to be careful.
The U.S. Army’s public affairs office at the Pentagon said that a man named Robert Russell Card II, whose birth date matches that of the suspect, is a sergeant first class in the Army Reserve who enlisted in December 2002. He was trained as a petroleum supply specialist, whose work involves shipping and storing vehicle and aircraft fuel.
He has not served on any combat deployments, according to Pentagon records.
Law enforcement agencies posted a photo on social media of the man they said they were seeking, wearing a brown hooded sweatshirt and carrying a military-style semiautomatic rifle.
Mr. Card was last known to be driving a white Subaru Outback with a black bumper, officials said. That vehicle was later found in the town of Lisbon, prompting a lockdown there. Colonel Ross confirmed that a vehicle found at a boat landing in Lisbon was connected to Mr. Card.
