Former Boston FBI agent John "Zip" Connolly is back in court, or at least his lawyers are. On March 16, 2026, his attorney filed a new motion in Florida claiming prosecutors sat on a handwritten manuscript by James "Whitey" Bulger that Connolly’s camp says could undercut his 2008 murder conviction. The filing asks a Florida judge to either throw out the conviction or grant a new hearing, reopening one of Boston’s most notorious corruption sagas yet again.
What Connolly Says Florida Prosecutors Hid
In the post‑conviction motion, Cambridge lawyer Peter Mullane argues that Florida prosecutors concealed a previously undisclosed handwritten manuscript by Bulger that, the filing contends, contradicts key state witnesses and could have helped Connolly’s defense, according to the Boston Herald. Mullane asks the court to vacate Connolly’s murder conviction or at least hold a new evidentiary hearing to dig into the newly cited pages.
The motion claims the manuscript goes straight at the credibility of state witnesses and at the long‑fought question of who inside law enforcement knew which underworld figures were secretly cooperating with investigators. Connolly’s team argues those are exactly the kinds of details jurors should have heard before they voted to convict.
From Star G‑Man To Convicted Felon
Connolly was convicted in 2008 of second‑degree murder for his alleged role in the 1982 killing of World Jai Alai executive John Callahan. That conviction stacked on top of an earlier 2002 racketeering case, eventually landing him a 40‑year sentence and a long trail of appeals and discovery fights over what evidence was or was not disclosed, according to The Boston Globe.
Now in his seventies and seriously ill, Connolly was granted a conditional medical release from a Florida prison in 2021, per CBS Boston. Even out of prison, he has continued to fight the underlying conviction that made him one of the most notorious disgraced agents in FBI history.
The Callahan Killing At The Heart Of It All
Prosecutors have long maintained that Connolly tipped Bulger and Stephen Flemmi that Callahan might cooperate with authorities. That information, they say, led Winter Hill hit man John Martorano to travel to Florida and shoot Callahan, whose body was later found in the trunk of a car at Miami International Airport. Martorano has admitted to the killing and cooperated with prosecutors, as reported by WBUR.
The new motion argues that the allegedly suppressed Bulger manuscript would further erode the testimony of those state witnesses. It also sits atop a paper trail in which FBI supervisors who oversaw Bulger’s status as an informant were later accused of corruption and, in some instances, granted immunity in related proceedings, according to earlier reporting in the Los Angeles Times.
Mullane’s filing contends the Bulger pages are both material and exculpatory, the legal buzzwords for evidence that should have been turned over before trial. If a judge agrees that the manuscript was improperly withheld and that it mattered to the verdict, Connolly wants the conviction vacated or, at a minimum, a full evidentiary hearing to reexamine what the jury was told and whether the verdict still holds up.
The Brady Fight That Will Decide What Happens Next
In Florida, a post‑conviction motion that alleges a Brady violation, the suppression of favorable evidence, can lead to an evidentiary hearing and sometimes even a new trial if the claim checks out. Florida appellate courts have, in past cases, ordered new proceedings or tossed verdicts when defendants proved that prosecutors failed to disclose important information, according to the state’s appellate record.
In Connolly’s case, judges will be asked to decide whether the Bulger manuscript is truly newly discovered evidence or just more of the same, and whether it is powerful enough that it could have changed the outcome at trial. Those are the questions framed in recent appellate rulings in Connolly’s long‑running litigation, including post‑appeal decisions documented by Justia.
State prosecutors will have a chance to respond to Mullane’s motion, and the court will decide whether to accept the filing for full briefing and a hearing. Connolly’s Florida move comes as his legal team continues to press parallel federal challenges and habeas petitions over the same conviction and the same disclosure fights. Related federal filings and prior orders are publicly available through GovInfo.
Victims’ Families Brace For Another Round
For the family of John Callahan and other victims who have fought Connolly’s release for years, this latest motion is another painful spin of the wheel in a case that has split judges, prosecutors and the public for decades. Some former prosecutors who worked aspects of Connolly’s cases have themselves faced scrutiny, and one veteran Miami prosecutor tied to high‑profile cases resigned in 2024 after a separate judge’s sharp rebuke, a reminder of how fraught big‑ticket litigation in South Florida can be, per the AP.
The Florida court has not yet set a schedule. Whether the Bulger manuscript leads to a full‑blown hearing, a vacated conviction or a quick denial will depend on how judges view its origins and whether it meets the strict legal standard for suppressed or newly discovered evidence. For now, Connolly’s filing keeps the spotlight on the enduring questions that first shook Boston’s faith in its hometown G‑men, how informants were handled, and what prosecutors shared, or failed to share, in the courtroom.
