Eighteen-year Pinellas County commissioner John Morroni died Sunday night while fighting his third battle against cancer.
Morroni, 63, announced in April that he was again undergoing treatment at Moffitt Cancer Center for a blood disorder known as acute myeloid leukemia.
Morroni's most recent leukemia battle is an effect of treatment he underwent for secondary myelodysplastic syndrome in 2016. In 2008 he was treated for non-Hodgkins lymphoma. His cancer returned in 2011 but was successfully treated.
