A man is in custody after knocking on the door of a Santa Rosa home with two loaded handguns and having several deputies answer. Johnny Perez of Clearlake was taken into custody early yesterday morning by deputies who were inside the Westberry Drive home conducting a search in an unrelated investigation. Perez is prohibited from having weapons or ammunition because of a prior felony conviction. Perez was booked into Sonoma County Jail in lieu of 30-thousand dollars bail on multiple weapons charges.
