Catherine Greig moved funds from one bank account to another and transferred her interest in her family’s house in South Boston to her twin sister in the months after she was arrested in June after 16 years in hiding with fugitive gangster James “Whitey’’ Bulger, prosecutors said in court filings Wednesday.
Federal prosecutors are seeking a court order to freeze Greig’s assets in accounts listed under her name and her sister’s name, and to place liens on her house in Quincy and the family house in South Boston.
The prosecutors allege that the assets could be subjected to fines imposed by the court now that Greig has pleaded guilty to harboring Bulger during their years in hiding, and they say that Greig’s past efforts to transfer her assets demonstrates the need to freeze the money now.
“It is in the government’s interest to ensure that any assets of the defendant that may be used to pay a fine or special assessment are preserved until the time judgment is entered against the defendant,’’ prosecutors said in the court filings.
Greig’s lawyer, Kevin R. Reddington, has said in court that she has voluntarily agreed to freeze her funds pending her sentencing in US District Court, slated for June 12.
Greig faces up to five years in prison and fines of up to $250,000 for each conviction: conspiracy to harbor a fugitive, conspiracy to commit identity fraud, and identity fraud.
Prosecutors said they are not seeking the forfeiture of her assets because they have not proven they were obtained through crimes. They could seek forfeiture if they find Bulger helped acquire her assets through crimes, prosecutors said.
But US District Court Judge Douglass P. Woodlock had asked for an accounting of Greig’s assets before her sentencing, noting that he has the authority to levy fines. Greig has been held without bail since she and Bulger were arrested.
According to court records, Greig, 60, still owns the Quincy house she bought for $160,000 in 1986, now assessed at $343,700.
In July, Greig moved to transfer any interest she may have in her family’s South Boston house on East Fourth Street. Prosecutors believe the transfer may be invalid, however, because of questionable deed records. That means Greig would still hold a 22 percent interest in the property, now valued at $617,500.
Prosecutors said that Greig’s twin, Margaret McCusker, obtained power of attorney on an account at Eastern Bank worth $134,545.49 that listed Greig as the trustee for a longtime family friend, Kathleen McDonough. McCusker withdrew the money in December and later that same day deposited it at Mt. Washington Bank.
That account now holds about $115,500, prosecutors say.
