Outgoing Franklin County Auditor Clarence Mingo is renewing his call for a change in state law to provide a property tax break to the spouses of first responders who die in the line of duty. "These families still carry on, they still have to manage through life, and property tax relief is one form of comfort that the government can provide," Mingo said Wednesday, the same day a public memorial service was held for the three-person crew killed in a medical helicopter crash in southeastern Ohio. "Survival Flight 14 is a real tragedy. However, this bill should gain momentum in light of this loss and also remind the public of the need to care for the surviving families of our first responders." Mingo, whose term as county auditor ends in March, has advocated over the past two years for passage of legislation granting an expanded homestead exemption to the spouses of officers, firefighters and other emergency responders who die in the line of duty or from a related injury or illness.
