What we know about the suspect

Robert Card, 40, has been identified as a person of interest in the shootings at Schemengees Bar and Just-In-Time Recreation.

A white Subaru Outback, which was the last vehicle Card was seen driving, was discovered near the Lisbon boat dock situated on Frost Hill Avenue, in close proximity to Route 196. Witnesses reported observing police officers going door to door in the vicinity, making inquiries at nearby residences, according to the Sun Journal.

He is a firearms instructor trained by the military and was recently committed to a mental health facility, according to a state police bulletin. The document says Card had been committed to a mental health facility for two weeks in the summer of 2023. It did not provide specific details about his treatment or condition.

The document also said Card had reported hearing voices and had threatened to carry out a shooting at the military training base in Saco, Maine.

Card is from Bowdoin, Maine, according to Commissioner Mike Sauschuck from the Maine Department of Public Safety.

President Joe Biden has been briefed as well putting out a statement Wednesday night: “The President spoke by phone individually to Maine Governor Janet Mills, Senators Angus King and Susan Collins, and Congressman Jared Golden about the shooting in Lewiston, Maine and offered full federal support in the wake of this horrific attack.”
