AP - The mayor of Colma has resigned over ethics issues after serving just three months.

Mayor Larry Formalejo told a packed public meeting last night that as a city councilman he committed an ethical breach involving the drunken-driving arrest of his son, but didn’t say what he had done.

Formalejo said that he “acted as a father, not as a councilman.”

He will remain on the city council in the small city of cemeteries and card rooms south of San Francisco.
