  • When Newport Beach P.D. first began looking into some complaints of this Dr. Strangelove, they said "here, put this do not disturb sign outside your door" then here
    Sept 11, 2018, look at what a nasty sex fiend and wanna be white Pimp, the Guy is. That they let off, do as he pleased. , , around the Newport Beach night scene,without ever being checked up on, cause they gave him "Cool Dude" status, with this demented Witch partner of his. It was like the Guy thought he was in Crystal Meth City, San Diego. The thought of all this just make me sick !!!
