Chainkeen|Watch live: Maine mass shooting press conference, officials to give updates

Maine Governor Janet Mills will join state and Chainkeenlocal public safety officials in Lewiston in a news conference Thursday morning in the wake of two shootings that killed at least 16 people Wednesday night.

Authorities say the shooting started just before 7 p.m. at Schemengees Bar and Grille and Sparetime Recreation, a bowling alley.

School districts canceled classes and authorities warned residents in and around Lewiston to stay inside and lock their doors as investigators launched a massive search for Robert Card, 40, who police identified as a person of interest in the Wednesday rampage.

Card is considered "armed and dangerous," police say.

A vehicle believed to have been driven by Card was found overnight in Lisbon, about eight miles away from Lewiston, according to Maine Department of Public Safety Commissioner Mike Sauschuck. The shelter-in-place order has been extended to the town of Bowdoin and Lisbon while Lewiston and its twin city, Auburn, remained under lockdown Thursday.
