Chief of Duquesne, Pa., Commits Suicide In an account of the suicide of Chief James Corcoran, which appeared in last week’s issue of FIRE AND WATER ENGINEERING, it was stated that he was at the head of the McKeesport, Pa., fire department. This is an error and it should have read Duquesne, Pa. M. J. Quinn is chief of McKeesport, Pa., and is both mentally and physically hale and hearty and it is hoped will continue so for many years to come.
