Denny Hecker's girlfriend, Christi Rowan, was arrested Wednesday night at the Sherburne County Jail where Hecker is confined.
Deputy U.S. Marshal Thomas Volk said she remains in custody there on a federal warrant charging she violated the conditions of her release while awaiting sentencing on fraud charges.
Earlier Wednesday, federal prosecutors had cited her "outrageous conduct," in demanding that she be jailed immediately and for 12 months. They said they had recently learned that she had once again helped scam the bankruptcy court handling the auto mogul's estate.
Rowan had been scheduled to appear in federal court Friday, where she faced up to six months in federal prison after pleading guilty last April to bank fraud and bankruptcy fraud in various schemes designed to aid Hecker.
Rowan, 37, has requested probation. But that is unlikely now. Neither Rowan nor her defense attorney, Janet Newberg, was immediately available for comment.
In a court statement issued late Wednesday, lead prosecutor Nicole Engisch said she recently learned that Rowan violated her plea agreement by withdrawing $9,000 from Hecker's U.S. Bank account and cashing at least $500 from secret dividend checks that Hecker received from Prudential stock. The stock's estimated value is $90,000.
Neither Hecker nor Rowan disclosed the stock or checks to the government as they were required to do, Engisch said. Rowan also ignored an injunction barring her from spending or transferring any of Hecker's bankruptcy estate, Engisch said.
"Rowan's pattern of deception did not stop with her guilty plea; did not stop when the bankruptcy court ordered her not to spend estate assets, and did not stop when this court ordered gift cards frozen in the Hecker case.
