DeKalb County police are piecing together details in a shooting Saturday inside a south DeKalb Pizza Hut that left an employee in critical condition and the alleged shooter dead from suicide.

Joshua McColle, an ex-boyfriend of an employee at the restaurant on Covington Highway, pulled out a gun after getting into a fight with another employee at about noon Saturday, according to Channel 2 Action News.

Samuel Wallace, 32, was shot twice and taken to the hospital in critical condition, police said. McColley's ex-girlfriend told police that the gunman demanded the eatery's security video but jumped away when customers arrived.  He then went into the back of the store and shot himself.
