In 1978, DeNaples pleaded no contest to a conspiracy charge of defrauding the government of more than $500,000 in contracts relating to the cleanup and recovery of the City of Scranton in the aftermath of Hurricane Agnes. Prosecutors claimed DeNaples plotted with three county employees to falsify records to obtain $525,000 in federal reimbursements. He was subsequently fined $10,000 and was placed on probation for three years. Four people, including Dave Osticco, the reputed underboss of the Bufalino crime family were convicted in 1982 of jury tampering in DeNaples fraud trial.
