LEWISTON, MAINE: Robert Card, 40, has been identified as at least one potential suspect in the mass shooting in Lewiston, Maine, CBS reports.

After the gunman was spotted driving a white 2013 Subaru Outback with license number 9246PD, police issued a BOLO notice.

The Subaru was discovered on Frost Hill Avenue, close to Route 196 near Lisbon boat dock. According to reports, Card was born on April 4, 1983.

Robert is from Bowdoin Centre, Maine, reports Marca. CBS News journalist David Begnaud tweeted that Card is a certified weapons instructor.

Card is thought to be stationed out of Saco, Maine, in the Army reserve.

In the summer of 2023, Card was admitted to a mental health institution for a few weeks after disclosing mental health difficulties.

Locals recall horrifying shooting in Maine

Legends Sports Bar and Grill owner Melinda Small stated that when a customer heard about the shooting at the bowling alley less than a quarter of a mile away at approximately 7 p.m., her staff promptly closed their doors and relocated all 25 patrons and staff members away from the entrance. The police ultimately filled the road, and four people at a time were led out of the building by a policeman. It's safe for everyone at the pub.

"I am honestly in a state of shock. I am blessed that my team responded quickly and everyone is safe, Small told The Associated Press. "But the same time, my heart is broken for this area and for what everyone is dealing with. I just feel numb."
