Co-conspirator’s name among sealed docs

The identity of an uncalled witness and an unindicted coconspirator in the Boston Calling extortion case will remain sealed after a judge tossed convictions in the case last week, but grand jury testimony of two former lieutenants of Mayor Martin Walsh could be revealed.

A federal judge last week vacated the convictions of extourism chief Kenneth Brissette and ex-head of intergovernmental affairs Timothy Sullivan, who prosecutors said pressured Boston Calling organizers into hiring union labor for a 2014 concert at City Hall Plaza.

Over 50 documents were unsealed with federal Judge Leo Sorokin’s ruling, while 12 pages remain sealed from the public’s eye. Among the secret documents are three relating to a witness who was not called by prosecutors during last year’s trial.

The documents related to the witness were filed at the same time as the feds’ requests to compel two City Hall aides, Joseph

Rull and Joyce Linehan, to testify under oath. Walsh was also among named witnesses who were not called to testify.

Three other sealed documents relate to the identity of an unindicted co-conspirator in the case. Just prior to the trial last July, Sorokin said in a ruling that prosecutors would not refer to the unindicted co-conspirator or make reference to statements.

Parties now have until Wednesday to object to the release of five exhibits, which include grand jury testimony and “reports” of former city attorney Patricia Malone, former Police Commissioner William Evans and concert organizer Brian Appel, according to a filing

Walsh’s office did not return a request for comment Sunday, but previously said it was reviewing Sorokin’s decision. Brissette and Sullivan resigned from their city posts after last year’s convictions.

U.S. Attorney Andrew Lelling’s office said last week it was “disappointed” by Sorokin’s decision and was reviewing its options.
