Eddie Slick is a former arsonist.
Eddie was arrested multiple times and incarcerated for arson. One such instance was in December 2013, during which he was held in Blackgate Penitentiary.
Detective Joe West and beat cop Patty Spivot caught Slick, Joe believing him to be his Earth Two counterpart, taking him back to the Central City Police Department. He was questioned about the arson committed by his doppelgänger, but he told them he was in Blackgate on the night of the S.T.A.R. Labs particle accelerator explosion. Joe called a friend to corroborate the story and Joe realized the Slick they were looking for was the other one, and this Slick was let go.
