Maine shooting suspect's mysterious death in cargo trailer leaves motive unanswered

The U.S. Army reservist responsible for the deadly shooting at a bowling alley and bar in Lewiston, Maine, took his own life inside a cargo trailer at a recycling plant where he once worked. The suspect, Robert R. Card, was found dead from a self-inflicted gunshot wound. The motive for the shooting, which left 18 people dead and 13 wounded, remains unknown. Investigators discovered a note addressed to a loved one at Card's house, indicating a mental health component to the tragedy. The community of Lewiston is slowly returning to normalcy after a two-day lockdown, and a candlelight vigil was held to honor the victims.
