Detective story

This is a police procedural that is pretty versatile despite having a simple gimmick. The protagonist has such an abusive childhood that he can see the last thing any on can see right before he or she died. The reoccurring part has to do with his past, how his trauma effects his life and his addictions or at least habits to keep the demons at bay. The procedural part is what is versatile. since what the victim saw would be different, the type of show would be different each week. If the victim saw the killer, saw everything, then the whole episode might be about finding the body, or finding the killer on the loose, or convincing the other police officers that the killer is the one, since they don't know his power. If the victim didn't see the murderer, then maybe just a clue, then the show is a murder mystery with a clue.
