Schools are shut down and residents are being advised to shelter in place as authorities search for a gunman in Wednesday night’s mass shootings at a bar and bowling alley in Maine.

An arrest warrant for Robert Card, 40, of Bowdoin, Maine, has been issued for eight counts of murder following an attack that left 18 people dead and 13 others injured in Lewiston, the state’s second-largest city, state police said at a press conference Thursday.

Only eight of the victims had been identified at the time of the press conference, resulting in only eight counts of murder, said Maine State Police Col. William Ross.
