Dominic Taddeo, 64, of Rochester, escaped after going to an approved medical appointment on Monday in Florida and did not return, according to the Democrat & Chronicle.
Taddeo was scheduled to be released from custody in less than a year, WHAM-TV reported.
Taddeo failed in two attempts in 1983 to kill mobster Thomas Marotta, WHAM reported.
In 2020 Taddeo asked for a compassionate release, citing health issues and the COVID-19 pandemic, but his request was denied, the Democrat & Chronicle reported.
