A massive manhunt is underway in Maine after a mass shooting that spanned two locations Wednesday night left at least 22 people dead and 30 wounded, Fox News' Jacqui Heinrich reported, citing a law enforcement source.

Maine Public Safety Commissioner Mike Sauschuck said in a late night news conference that law enforcement is not yet confirming an exact number of victims since the situation remains "very fluid."

Wednesday’s death toll is staggering for a state that recorded 29 homicides for the whole year in 2022.

While a suspect has not yet been named, the Lewiston Police Department identified 40-year-old Robert R. Card, of Bowdoin, Maine, as a person of interest Wednesday night. According to an internal Maine Information and Analysis Center bulletin obtained by Fox News, Card is a firearms instructor and has military experience.

Fox News' David Spunt reported, citing a senior law enforcement source, that authorities are aware Card may have a police scanner and could be actively listening to some of their movements. The FBI has added dozens of agents to the scene over the past few hours to assist local law enforcement. SWAT teams are also on the ground and mobilized.

Card is believed to be in the Army Reserve stationed out of Saco, Maine, according to the bulletin.

Authorities said Card should not be approached if seen as he is considered "armed and dangerous."

"Law Enforcement is attempting to locate Robert Card 4/4/1983, as a person of interest regarding the mass shooting at Schemengees Bar and Sparetime Recreation this evening," Lewiston police announced in a Facebook post. "Card should be considered armed and dangerous. Please contact law enforcement if you are aware of his whereabouts." 

Local news outlets report the bowling alley was recently renamed to Just in Time Bowling, but is better known by its former name, Sparetime Recreation.

Authorities told residents in Lewiston to "shelter in place" and to "stay inside your home with the doors locked."

At midnight on Thursday, the Maine Emergency Management Agency (MEMA) announced that the shelter-in-place order had expanded to include the town of Lisbon.

The expanded order comes after authorities found Card's white Subaru Outback near the Lisbon boat dock on Frost Hill Avenue near Route 196.

Androscoggin County officials ultimately issued a shelter-in-place order for the entire county and told residents to "make sure your homes and vehicles are secured."
