A 25-year veteran of Cleveland's fire department sued the city and several employees Monday claiming he was subject to retaliation based on an erroneous belief that he had leaked damaging information about a former fire chief. Sean DeCrane, who retired in September as Third Battalion chief, contends he warned city officials in January 2013 that former fire division Chief Daryl McGinnis lacked required continuing training and certification needed to hold his position. That was before the city named McGinnis as fire chief. At the time DeCrane was in charge of the fire training academy that tracked such records.
