A baby boy strangled by his mother alongside his brother and sister has died three days after his siblings.
Lindsay Clancy, 32, is accused of killing her daughter Cora, 5 and son Dawson, 3, at the family home in Massachusetts and attacking baby Callan, who is eight months old.
Plymouth County District Attorney confirmed that Callan died at a Boston area hospital on Friday morning.
Clancy and Callan both initially survived the apparent murder-suicide attempt – with the mother-of-three jumping out of a window on the top floor of the property.

Her horrified husband, Patrick, 34, discovered Clancy lying unconscious outside their home when he returned from work at around 6pm on Tuesday and called 911.
Clancy is still being treated in hospital, currently under police custody, and will be arraigned on homicide charges after she is released.
Investigators are probing if the midwife was suffering from post-partum depression, as she was on leave from her job at Massachusetts General Hospital.
Friends of the Clancy family have set up a GoFundMe to support Patrick and assist in paying for medical bills, funeral bills and legal bills.
So far it has raised $438,224 of the $700k goal, with the page adding: ‘This assistance is especially needed because Pat will be unable to work for the foreseeable future as he weathers this painful, life-altering tragedy.
‘We all know Pat to be the most kind and genuine person. As someone who is always willing to support others, we sincerely thank you for offering yours.’

A vigil took place on Thursday night at the Holy Family Church in Duxbury, with a priest saying that the mother had been ‘trying to deal with mental illness’ before becoming ‘overwhelmed’.
Officers arrived at the family home on Tuesday after a frantic Patrick had discovered his wife unconscious on the ground below a second-floor window.
They discovered the three young children ‘unconscious’ upstairs’ with obvious signs of trauma’.
Plymouth District Attorney Timothy Cruz said it appeared that they had all been strangled.
Cora and Dawson were pronounced dead on arrival at hospital, while Callan was given CPR at the scene.

Clancy will be arraigned on charges including two counts of homicide and three each for strangulation and assault and battery with a deadly weapon for the deaths of her two children.
It is expected that further charges will be added for the death of Callan.
Cruz said they will now conduct autopsies to determine how the children died. Findings will be made public when a death certificate is issued.
In a press conference Cruz said of the family: ‘I cannot begin to fathom the pain, the depths of pain they must be feeling.
‘This is an unimaginable, senseless tragedy, and it is an ongoing investigation.’
Cruz warned, ‘nobody’s here to speculate’, adding ‘we’re well aware of the fact that anybody charged with a criminal crime is presumed innocence until proven guilty beyond a reasonable doubt.’

He wrapped up the conference by saying: ‘Certainly our hearts and condolences go up to the Clancy family’.
Lindsay Clancey’s father-in-law, Christopher Clancy, said: ‘We’re all heartbroken right now.’
Clancy had previously shared online that she was struggling with postpartum anxiety.
While Lindsay appeared to be a proud mother on Facebook, she shared about struggling with postpartum anxiety after the birth of her latest child.
Last July, she wrote that six weeks after the child’s birth, she was feeling ‘dialed in’ and sought to focus on exercise, nutrition and her mindset, which she claimed ‘made all the difference.’
In 2020, she wrote online: ‘So unbelievably thankful for this family and life,’ along with doting images of her children, reports Boston Globe.

Feelings of depression can be common after childbirth, but on rare occasions, they can lead to full postpartum psychosis.
In this extreme form of PPD, a mother can suffer from severe depression and hallucinations which can lead her to harm herself, her children, or both.
The hospital where Lindsay works said in a statement: ‘We are shocked and saddened to learn of this unthinkable tragedy. We extend our deepest sympathies to all those affected by these devastating events.’
