A man accused of ripping off Hawaii convicts serving prison time on the mainland and their families in a $3 million Ponzi scheme pleaded not guilty to wire fraud and mail fraud charges this morning in federal court.

A federal judge set a March trial date for Perry Jay Griggs and ordered him held in custody without the opportunity for bail pending trial.

Griggs’ wife Rachelle pleaded not guilty to the same charges last week.

The couple were fugitives from last October, when a federal grand jury in Hawaii returned an indictment against them, until their capture in Arizona last month. They are accused of running a Ponzi scheme from 2003 to 2008 while Perry Griggs was in a federal prison in Las Vegas for operating another Ponzi scheme in California.
