Matthew Kadai

Matthew Kadai is the assumed name of an otherwise unidentified murder victim who was attacked by Andrew Carter.

Batman: Arkham Origins
The man only assumed to be Matthew Kadai was attacked at the Amusement Mile by a then-recently released hardened criminal named Andrew Carter, who by that point stopped going to court-mandated therapy sessions, was planning to join Bane's mercenary group, and was very dangerous. He was killed when Carter, having been enhanced by the drug Venom, threw an air conditioning vent at him, breaking every single bone in his body and thus making it appear as if he had suffered repeated physical blows. He was in his thirties when he died. Batman, having learned of the murder from a police dispatch, investigated the murder and deduced Carter's involvement. Alfred and Batman then tracked down Carter alongside a unit of Bane's mercenaries to Park Row and knocked him out, also leaving him to be picked up by the GCPD.
