May 18, 1947
Passengers on the "O" line streetcar had their peaceful passage disturbed today when an automobile, estimated to be traveling 60 mph, smashed into the back of the trolley as Motorman Charles Carringer, 33, of 2451 3/4 Daly Street was about to pull away from a stop at College and North Main Streets.
Passenger Antonio V. Castillo, 30, of 618 S. Ferris Street, was killed instantly. The driver, Paul Z. Guerrero, 25, of 184 Darwin Street, was taken to the General Hospital prison ward, where he was treated for lacerations before being booked on a charge of manslaughter. Mr. Castillo has the posthumous distinction of being the county's 300th traffic fatality.
