The mistrial has left Lindsay Clancy's criminal fate unresolved, prosecutors have not said whether they will seek a retrial and the next court hearing is scheduled for 29 September at Plymouth Superior Court in Massachusetts.

In his first broadcast interview since the jury deadlocked, Patrick Clancy said he decided to forgive his former wife so he would not be "eaten up inside forever." Speaking to CBS, he attributed the actions that left their three children dead to severe mental illness and said headlines that labelled her a "Killer Mom" and "Monster" were inaccurate.

Prosecutors had alleged that on 24 January 2023, Lindsay Clancy intentionally strangled Cora, five, Dawson, three, and Callan, eight months, at the family home in Duxbury. Her defence team argued she suffered from postpartum psychosis, a rare condition that can cause mania, depression or a mixture of both. The judge declared a mistrial earlier this month after the jury could not reach a unanimous verdict.

Patrick Clancy told CBS he testified during the trial about his ex-wife's deteriorating mental state after childbirth and that he believes he "did the best I could with what I had at the time." He also said living with the outcome is a daily burden and admitted he had suicidal thoughts in the weeks following the tragedy, adding that he did not think he would live to see his 35th birthday.

During the seven-week trial, Patrick became the target of intense online abuse and allegations that he covered up aspects of the case. He said the speculation and photographs of him travelling and with his new wife, Rachel Danis, were "deeply harmful to the legacy of my children" and distracted attention from perinatal mental health, which he said was the central issue.

After the publicity, he moved from Duxbury to New York City in search of anonymity. He and Danis are starting a family and he said he looks forward to telling future children about their siblings. Lindsay Clancy, 36, was left paralysed after jumping from a second-floor window following the killings and attended the trial in a wheelchair.

With the trial concluded by mistrial rather than verdict, the legal question of whether prosecutors will pursue a new prosecution remains open and will be clarified at the next hearing on 29 September.
