Shelter-in-place orders are in effect in Maine after a deadly mass shooting in Lewiston on Wednesday night left at least 18 people dead and 13 more injured. Authorities are still searching for the shooter, who they believe to be Robert Card, a 40-year-old certified firearms instructor and U.S. Army reserve member. Police say Card is still at large, and they have not announced any arrests in relation to the shooting. 

Viral posts from “verified” users on X (formerly Twitter), however, claim that the main suspect has been taken into custody.
