In the latest fallout from the state’s continually evolving crime lab fiasco, a hearing officer for the Massachusetts Board of Bar Overseers has recommended sanctions against three former assistant attorney generals for the “spectacular” harm they caused the public, the criminal justice system and scores of drug defendants.

The rare rebuke of state prosecutors follows the state high court’s dismissal of roughly 35,000 drug convictions across Massachusetts — including hundreds of felonies in Bristol County — due to chemists’ misconduct at crime labs in both Amherst and Jamaica Plain.

Special Hearing Officer Alan D. Rose recommended a two-year suspension for Anne K. Kaczmarek, lead prosecutor in the case against disgraced crime lab chemist Sonja Farak. Kaczmarek intentionally withheld exculpatory evidence from drug defendants challenging their convictions based on tests that Farak conducted at the state lab in Amherst, Rose found. Farak pleaded guilty in 2014 to tampering with and stealing drug evidence at the lab.

Rose, retained by the board to evaluate the misconduct charges, also recommended former assistant attorney general Kris C. Foster be suspended for a year and a day.   Foster made false statements to judges considering the challenges to drug convictions brought by defendants who were convicted with evidence Farak had tested, Rose found.

Rose found Foster exhibited a “pervasive lack of candor and truthfulness” and a “lack of remorse” for her conduct during disciplinary hearings last year.

Rose recommended a public reprimand for former assistant attorney general John C. Verner for failing to properly supervise Kaczmarek.

The suggested penalties are the latest repercussions in the drug lab scandal, which first spilled into public view nearly a decade ago with the arrest of chemist Annie Dookhan. 

Dookhan pleaded guilty in 2013 to tampering with drug samples at the William A. Hinton State Laboratory Institute in Jamaica Plain.

The state’s highest court has dismissed roughly 35,000 drug convictions due to the misconduct of Dookhan at the Hinton Lab and Farak in Amherst in what has become the biggest crime lab scandal in U.S. history.

Dookhan and Farak collectively served less than five years behind bars.

Rose found Kaczmarek intentionally withheld mental health worksheets found in Farak’s car after her 2013 arrest that indicated she struggled with a severe drug addiction. The information revealed Farak’s habit could have affected her work far longer than just the six months predating her arrest, as the attorney general’s office claimed.

In fact, Farak admitted in 2015 grand jury testimony that her drug use at the Amherst lab began after she arrived there in 2004 and she was on drugs “nearly every day, all day.”

Defendants who sought the exculpatory evidence, Rolando Penate and Lizardo Vega, remained imprisoned because the worksheets were withheld. Those cases were later dismissed.

“Kaczmarek displayed no remorse, admitted no wrongdoing, and showed no appreciation for her role in what occurred,” Rose wrote. He said Kaczmarek caused “great harm to the third-party defendants, the system of justice and the public at large.”

Rose’s recommendation for Kaczmarek is far short of the disbarment urged in August by the state Bar Counsel’s office, which brought the ethics charges against the prosecutors.

Rose acknowledged in his 25-page decision that Massachusetts prosecutor discipline is rare, and there is no precedent for the misconduct committed by the three lawyers in the unparalleled drug lab crisis.

Rose’s recommendations must be approved by the Board of Bar Overseers and the state’s highest court.

Bruce A. Green, a former federal prosecutor who now directs the Louis Stein Center for Law and Ethics at Fordham University Law School, said there is no guarantee Kaczmarek will be readmitted to the bar if she seeks reinstatement.

Despite Kaczmarek’s long career as a prosecutor with no prior allegations of improprieties, she would still need to persuade the board and the Supreme Judicial Court, which reinstates lawyers to practice, that she acknowledged her mistakes and would not repeat them.

“That is going to be an uphill battle,” Green said.

Kaczmarek’s attorney, Thomas R. Kiley, did not respond to a request for comment on Monday.

Kaczmarek is no longer working as an attorney. Foster is the general counsel for the state’s Alcoholic Beverage Control Commission. Verner is a prosecutor at the Suffolk County District Attorney’s office.

Rose found that Foster misled Judge C. Jeffrey Kinder during an Oct. 2, 2013, hearing, falsely claiming all exculpatory evidence had been turned over to defendants.

Rose also laid some blame on Foster’s superiors in the attorney general’s office, who have not been charged with misconduct.

Foster lacked the legal experience to handle the matter before Kinder and had relied on Kaczmarek’s claim that the material had been disclosed. Kinder denied the defendant’s requests for relief, partly because of Foster’s assurances.

Rose also found Foster was evasive during disciplinary hearings last year and made “false and misleading” statements to Superior Court Judge Richard J. Carey, who held lengthy hearings in 2016 to consider challenges to convictions brought by defendants whose evidence Farak had tested in Amherst.

“Foster showed pervasive dishonesty across three tribunals. This is deeply disturbing” Rose wrote. Foster’s conduct “undermined confidence in the public’s perception of the fairness of the criminal justice system in Massachusetts,” he wrote.

Foster’s attorney, Allen N. David, said: “We are disappointed in the decision. We had expected and hoped for something less.”

David said he plans to appeal Rose’s recommended sanction for Foster.

He said Rose appeared to base his recommended suspension for Foster on “intentional misconduct” she was never charged with committing.

According to Rose’s decision, that included “dishonesty before Kinder” during the Oct. 2, 2013, hearing and “false testimony under oath” before Judge Carey.

It is unprecedented in Massachusetts to suspend a lawyer for a year for conduct the Bar Counsel did not charge her with committing, David said.

Rose also credited Verner’s honesty in ensuring in 2014 that the mental health worksheets and other evidence be immediately turned over to defendants, once Verner learned it had been withheld.

“. . . . Verner demonstrated candor, remorse, and recognition of and responsibility for his mistakes,” Rose wrote.

Verner’s attorneys, Patrick Hanley and Thomas J. Butters, said of Rose’s decision:

“The Special Hearing Officer’s findings as to John’s candor, remorse, insight and responsibility are emblematic of who he is as a person and attorney and are consistent with what Judge Carey found four years ago, which is that John was a “committed and principled public servant.”
