The president of the Lloyd, Carr & Co., commodities option firm, who is out of jail on $100,000 bond awaiting a hearing on charges of defrauding his coustomers, is actually an escaped convict with a list of convictions and aliases, according to the Federal Bureau of Investigation.

James A. Carr, 53, of Marblehead, Mass, was arrested last week along with several officials of his firm, Lloyd, Carr & Co. They were charged with contempt for continuing to defraud customers in the high-pressure sale of London options in a cintroversial investment scheme. There had been a previous federal ruling ordering them to stop such practices.

Carr posted $100,000 cash bond when he was arrested a week ago, and officials fingerprinted him and released him.

But a fingerprint check later revealed that Carr was a man authorities know as Alan Abrahams, Alan Abrams, and Alan Layne, who is wanted for his escape from a New Jersey state prison in Trenton, federal parole violations in New York City, and passport fraud in Canada. He was serving an 18-month sentence in New Jersey.

According to Assistant U.S. Attorney Michael Collora in Boston, Carr has been convicted at least twice for interstate transportation of a forged check in New York and for obtaining money under false pretenses in New Jersey.

Officials at the Commodity Futures Trading Commission in Washington said Carr also was jailed in New Jersey on tax evasion charges.

The CFTC has been working with local law enforcement agencies and U.S. attorneys around the country in an effort to stop Lloyd, Carr from selling any more London options without permits.

At that time, Lloyd Carr applied for registration with the agency, but refused to open up its books to agency inspection. Consequently, Lloyd Carr was not approved.

His lawyer, F. Lee Bailey, could not be reached for comment.
