I’ve watched every single one of these.
A COLD CASE is a police term for an unsolved crime aka They Got Away With Murder!
Some people, when never caught in their F1RST crime, will escalate their twisted and strange fetishes until the day they die.
And when they die?
Are they happy that they were never caught? Do they go with a SMUG SMILE on their face?
Or with a rictus of horror for multiple dues owed?
Or do they call in Bruce Willis to do a Death Becomes Her make-over?
Dunno. Don’t need to know.
