Two senior law enforcement sources told Fox News that the Lewiston, Maine shooting suspect Robert Card planned Wednesday night’s shooting well in advance and had several hiding spots ready for him to go to.

Police in Maine identified Card as a suspect for shootings at two different locations — the Schemengees Bar and Grille and the Just-In-Time Recreation bowling alley — on Wednesday night, leaving at least 18 people dead and 13 injured.

More than 36 hours after the deadly rampage, authorities have not yet located Card.
