What is the name of the murder show that showed this episode?

Ok so I don’t remember which show this is, I thought it would probably be something like CSI, Criminal Minds, the Mentalist, something along those lines, but there is this one episode I want to look up and I can’t remember which show it is from. It is about a Man who goes to the park everyday to run and one day he feels like someone is stalking him and it is this really creepy clown(and he hates clowns) and they find him dead because he shot him and and one of his fingers is gone because apparently later on they find out he had this safe and you put your finger in to unlock it and its under his bed, and it ends up being his wife in the clown suit that killed him because she was the only one who knew about how he was really afraid of clowns an that he had a safe under his bed and how he went to the park every morning and what time. So yeah. So if anyone knows what show this was please tell me :)
