In a courtroom twist echoing past cases, the judge overseeing Lindsay Clancy’s high-profile murder trial is no stranger to notorious cases involving mothers accused of killing their children. A prior decision by this seasoned judge to exclude key medical evidence once led to a dramatic retrial in a similar case.
Judge William F. Sullivan, at 69 years of age, is at the helm of Clancy’s trial, where she faces accusations of deliberately ending the lives of her three young children. Prosecutors argue that the former nurse carried out these tragic acts with premeditated intent.
Sullivan, whose judicial journey began with an appointment by then-Governor Deval Patrick in 2014, has a history of grappling with similarly harrowing cases. Just four years ago, he handled a case with haunting similarities to Clancy’s that resurfaced in the courts due to a retrial.
Back in 2022, Judge Sullivan was at the center of the murder trial of Latarsha Sanders, another Massachusetts mother accused of heinous acts. Sanders faced charges for the murder of her two sons under circumstances that shocked the community.
A jury in December 2022 found Sanders guilty, persuaded by the prosecution’s case that she had brutally stabbed her sons—eight-year-old Edson Brito nearly 80 times and five-year-old La’Son Brito more than 20 times—in a macabre ritual she described as rooted in Voodoo practices.
The jury deliberated for around four hours, and found the mother guilty. Sullivan sentenced Sanders to two mandatory life terms without the possibility of parole.
However, Massachusetts’s highest court, the Supreme Judicial Court, unanimously vacated Sanders’s conviction on August 6 of this year in a stunning U-turn.
The top court stated that Judge Sullivan was wrong to exclude relevant medical records at the 2022 trial, which showed Sanders’s psychosis and ill mental state.
Sanders was granted a new murder trial this year.

Sanders was granted a new trial after she argued on appeal that Sullivan was wrong to have prevented the defense from presenting the jury with the mother’s post-arrest medical records
Justice Frank M. Graziano wrote: ‘We hold that the exclusion of the defendant’s relevant medical records relating to the diagnoses or treatment of mental illness constituted prejudicial error, and as a result, the defendant is entitled to a new trial.
Sanders admitted to murdering her children in February 2018, and during the first trial, her attorney argued an insanity defense – the same assertion Lindsay Clancy’s attorney has made in her triple filicide trial.
Like Clancy, they claimed Sanders was in the throes of a psychotic episode during the murders, therefore meaning she lacked criminal responsibility.
During her trial in 2022, Sanders’s defense attorney tried to present medical records that showed she was diagnosed with schizophrenia psychosis after the killings.
Clinical neuropsychologist Dr. Thomas Deters had conducted interviews with Sanders lasting nine hours in total, as well as seven hours of neuropsychological testing.
The doctor had concluded that Sanders was ‘grossly psychotic’ at the time she killed her children, suffering ‘hallucinations’ that had been untreated for decades. Sanders had ‘schizophrenia spectrum and other psychotic disorders,’ his diagnosis stated.
The doctor’s findings were detailed in thousands of pages of medical records, but just as Deters was about to take the stand, the prosecution objected.

They claimed the medical records were irrelevant, and demanded they’d be blocked from being presented in front of the jury as evidence.
Judge Sullivan agreed – preventing the potential evidence from being used in the trial.
Now that Sullivan has been called out by the Supreme Judicial Court for his erroneous decision, Sanders will stand trial once more.
Her new trial will take place in Massachusetts Superior Court, and her defense is likely to argue insanity again.
It is unclear which judge will oversee her new trial.

Some activists in Boston have highlighted the relative lack of coverage of Sanders’s case and sympathy for the killer mother compared to Clancy. They have questioned whether this was due to Sanders being black and poor.
Sullivan, who is a married father-of-three who lives in his $905,700 home in Canton with his wife, Mary Lou, will also determine Clancy’s fate at sentencing.
Sullivan earned his law degree from Boston College Law School in 1982 and was admitted to the Massachusetts bar that same year.
Prior to joining the bench, Sullivan worked as an assistant district attorney in the Norfolk County District Attorney’s office in the early 1980s, according to Massachusetts Lawyers Weekly.
He also worked as a special assistant to the Quincy city solicitor from 2006 to 2008.
Additionally, he worked as a defense attorney with the practice Sullivan and Sweeney before he was appointed judge.
Clancy, 36, is accused of murdering her three children, Cora, five, Dawson, three, and eight-month-old Callan, at her home in Duxbury, Massachusetts , in 2023.
She strangled her children with exercise bands and then allegedly attempted to kill herself, but her efforts failed and left her paralyzed from the waist down and in a wheelchair for life.
Clancy has admitted to killing her children but pleaded not guilty to murder by reason of insanity, citing postpartum psychosis, and is seeking to be committed to a state mental health facility rather than face a prison sentence.
