Maine Shootings: What We Know About 'Armed and Dangerous' Suspect, Now Wanted for Murders

Eighteen people were killed and 13 were injured during Wednesday night's mass shootings in Lewiston, Maine

The suspect in Wednesday's mass shooting in Lewiston, Maine, in which 18 people were killed and 13 were injured, is still at large and is considered "armed and dangerous," according to Maine Governor Janet Mills.

Robert Card, 40, is a Petroleum Supply Specialist in the U.S. Army Reserve, Army Spokesman Bryce Dubee tells PEOPLE. Eight of the fatal victims have been identified, so an arrest warrant has been issued for the suspect on eight counts of murder.

The Associated Press, citing a state police bulletin, reports the suspect is a military-trained firearms instructor who had recently been committed to a mental health facility for two weeks this past summer.

At a Thursday press conference, Col. William Ross of the Maine State Police encouraged people who come into contact with the suspect or anyone resembling him to call 911.

Authorities said the first call about the violence came at 6:56 p.m. reporting a shooting at Just-In-Time Recreation, a bowling alley. At 7:08 p.m., a call came in about a shooting at Schemengees Bar and Grille, about four miles away.
