Ex-Dealer Gets 2nd Sentence for Continuing to Bilk Clients

David O. Naulin, a former securities dealer who continued to defraud customers while he was serving a prison sentence for fraud, was sentenced Monday for a second time.

In federal court in Los Angeles, Naulin was ordered to serve 41 months in prison and five years of supervised release. He must also pay restitution of $1.189 million for commodities and mail fraud for bilking clients out of more than $1.5 million.

Naulin, a 34-year-old Newport Beach resident, had been convicted in 1989 of securities and mail fraud and was serving a one-year sentence in a halfway house. He reported to the house at night but had his days free. During that time, he posed fraudulently as a member of the New York Futures Exchange, court authorities said.
