At least 22 people were killed and 50 to 60 wounded on Wednesday in mass shootings at multiple locations including a bowling alley and a bar in Lewiston, Maine, NBC News reported, citing a Lewiston police source.

The Lewiston Police Department on Facebook identified a person of interest in the mass shooting at the bar and bowling alley as Robert Card, 40, saying he should be "considered armed and dangerous."

Police earlier posted three photographs of an unidentified suspect pointing what appeared to be a semi-automatic rifle, in addition to a picture of a white SUV, asking the public for help in identifying either.
