A Massachusetts nurse has been accused of killing two of her three young children and leaving her infant in critical condition before attempting suicide by jumping out a window, the Plymouth district attorney announced Wednesday.

Lindsay Clancy, 32, is in police custody as she recovers in a Boston hospital and will be "arraigned as soon as possible" on two counts of homicide for the deaths of Cora Clancy, 5, and Dawson Clancy, 3, District Attorney Timothy Cruz said. 

She will also be charged with three counts of strangulation as well as assault and battery with a deadly weapon, according to Cruz. 

There was speculation based off recent Facebook posts that Clancy suffered from postpartum depression, but Cruz declined to say if this was a contributing factor.

"In incidents like this, there are usually more questions than answers," Cruz said during Wednesday's press conference. "We aren't here to presume motives … This is an unimaginable, senseless tragedy, and it is an ongoing investigation."

Clancy's husband called 911 at 6:11 p.m. Tuesday after his wife attempted suicide by jumping from a window of their Duxbury home, which is a coastal town about 30 miles south of Boston. 

Responding officers found the children "unconscious with obvious signs of trauma," Cruz said. 

The surviving child was a 7-month-old boy, who was flown to a Boston children's hospital, where he remains in critical condition.

Authorities didn't have an update on the baby's condition during Wednesday's press conference, and the district attorney's office didn't immediately respond to Fox News Digital's email about an update Thursday morning. 

Clancy is a labor and delivery nurse at Massachusetts General Hospital, which issued a statement to the media on Tuesday. 

"We are shocked and saddened to learn of this unthinkable tragedy," Michael Morrison, the senior director of external communications, said. "We extend our deepest sympathies to all those affected by these devastating events."
