At some point each week, every man has an entirely reasonable motive for killing his wife/girlfriend. (Some women may also feel that they have, but invariably any problems they have are actually their own fault.) The prohibiting factor in actually doing this is normally prison and the associated male rape and salad tossing.
Unless you have so much money and fame that you are not going there regardless, not being caught is therefore integral to this pursuit.
The killing:
Though actually used to kill in 'Hannibal', I include a pig farm from it being suggested in 'Porky's', a more believable film. 'Hellraiser III' revealed the previously-unconsidered CDs to also be a possibility.
Disposal of the body:
The best of these choices is clearly the hospital medical waste, where the presence of body parts are unlikely to be viewed as suspicious.
I live near a hospital.
Your defence at trial:
The only defence that has any hope of success is that of insanity. You can assist yourself to this end by publicly urinating in unsuitable places for a period of months before committing murder.
I am opting for the corner of my office, as this has the added benefit of full pension on the grounds of mental ill-health.
