On December 29, 1992, while under house arrest with an electronic monitoring device, Scarpa lost an eye in a shootout with other mobsters. Two Lucchese family mobsters, Michael DeRosa and Ronald Moran, had threatened Joey Scarpa, Gregory's son, over a drug deal. Climbing out of bed, the elder Scarpa drove with Joey to DeRosa's house and shot DeRosa. Moran fired back and hit Scarpa in the eye. Back at his house, Scarpa allegedly poured some Scotch Whisky into his wound, assured the authorities everything was fine, and later went to the hospital. Prosecutors revoked Scarpa's house arrest and sent him to jail.
