I'm always amused when people dress up for their suicide. Their clothes will only be cut off when undressing them for the autopsy, or, if not found for a while, will be ruined by decomp fluids...
Nothing amusing about that. THey made a decision to die with dignity.
And, the bastard was actually married to some other woman residing in Spain - they were just lovers and as already mentioned, his jealous streak drove him to murder his girlfriend, then killed himself.
