Detective Sergeant Robert "Copper" Constable was destined to be a police officer. His father was a Street Cop, killed in the line of duty when Copper was still in his teens, which drove him from an early age to follow in his father’s footsteps. Constable has a reputation as one of the few Honest Policemen left in the City, and refuses to just let a case close without fully investigating to its inevitable conclusion, which puts him at odds with the Chief of Police, and at times the other detectives in the Department.
