Father Asks Aid to Find Youth
Missing since April 27 17-year-old Leonard Zeb of 3322 Garringo street, Fruitvale, is being sought by his father, who has asked the aid of both the Oakland and San Francisco police forces.
He is the only child and his father can give no reason for his disappearance other than the fact that the boy always had been of an adventuous [sic] nature. It is thought the boy may have signed on some sea-going steamer as his father is a sea captain and the boy has always wanted to follow the life of a sailor.
