Jonathan Bristol, a former partner of Winston & Strawn, is expected to plead guilty to charges in connection with the alleged laundering of money for now-imprisoned money manager Kenneth Starr. Assistant U.S. Attorney Michael Bosworth told Southern District Judge Deborah A. Batts yesterday that an agreement in principle has been reached concerning a disposition in the case.

Mr. Bristol was arrested in December and accused of laundering more than $20 million through his attorney escrow accounts for Mr. Starr, who was running a $33 million Ponzi scheme (NYLJ, Dec. 17, 2010).

Mr. Bristol served as counsel to Mr. Starr and his financial firms since at least 2007, according to a companion civil suit filed by the Securities and Exchange Commission that accused Mr. Bristol of aiding and abetting Mr. Starr’s fraud.

Judge Shira A. Scheindlin last week sentenced Mr. Starr to serve 7½ years in prison.

Mr. Bristol’s attorney, Susan Kellman, could not be reached for comment. Judge Batts set a May 2 deadline for a possible plea by Mr. Bristol.
