July 25, 1962
Lieutenant assigned to Rescue Squad 1, was one of several firefighters injured at the DuVall Transfer and Deliver Service at 3 Talbot Avenue on November 14, 1954. Firefighters responded to three explosions in trucks parked at the rear of the building. As they worked to extinguish those blazes, a fourth and more powerful explosion occurred inside the building, injuring a number of firefighters and civilians. O'Neill was transported to St. Joseph Hospital and treated for cuts, bruises, and internal injuries. He was unable to return to duty until January 1960. The lingering effects of his injuries continued, however, and he died on July 25, 1962. Lieutenant Mike O'Neill, 44, was married and the father of three children.
