New Kensington’s only volunteer firefighter to die in the line of duty has been gone longer than he lived, but he has not been forgotten. Eric Lee Mangieri was 25 years old when he became trapped in a burning house on Freeport Road on Aug. 7, 1995. A memorial to him stands outside the city’s No. 4 fire station on Seventh Street, where he had been a member for just two years.
