The Las Vegas Strangler (1968)

aka

No Tears for the Damned 

A man driven insane by his adulterous wife and domineering mother terrorizes the city of Las Vegas, brutally murdering streetwalkers and homosexuals.

(IMDB)

Actually his wife never cheated on him, had nothing to do with his crimes and he didn't murder any homosexuals and the ladies killed weren't all necessarily streetwalkers.
