The lawyer representing Catherine Greig, the longtime girlfriend of notorious New England mob boss James “Whitey” Bulger, claimed in court on Monday his client intends to plead guilty to a federal contempt charge.

Christina Sterling, spokesperson for the United States Attorney’s Office in Boston, confirms to PEOPLE that attorney Kevin Reddington stated in court on Monday that Greig is planning on entering the plea soon.

Reddington did not respond to PEOPLE’s repeated requests for an interview Tuesday.

Sterling says a “written plea agreement” hasn’t been presented to the court just yet, and there’s no timeline for when Greig will reverse her original not guilty plea.

A date for the plea has not been set, Sterling says.

The longtime female companion of Bulger spent 16 years on the run with him when he was a fugitive.

Greig, 64, was indicted in September for criminal contempt for refusing to testify before a grand jury about whether other people helped the couple hide.

The former dental hygienist and dog groomer fled Boston with Bulger in 1995 and was arrested with the gangster in 2011 in the garage of their rent-stabilized apartment in Santa Monica, California, where they lived under the names Carol and Charlie Gasko.

Greig is serving an eight-year-sentence at a minimum security prison in Minnesota after being convicted of identity fraud and harboring a fugitive.
