Two children have died after they were found unconscious inside a Massachusetts home Tuesday night. Another infant and a woman were rushed to the hospital, Plymouth District Attorney Timothy Cruz said.

Cops rushed to a residence on Summer Street around 6:15 p.m. while responding to a 911 call after a man found the woman attempting suicide, CBS News reported.

As they reached the scene, investigators found the woman had tried to jump out of the window of the residence.

While conducting a search of the house, cops and firefighters found three children — a 5-year-old girl, a 3-year-old boy, and an 8-month-old baby — unconscious.

All three reportedly had "obvious signs of trauma" and were immediately rushed to the hospital along with the woman, Cruz said during a press conference outside the Duxbury police station.

While the 5-year-old girl and 3-year-old boy were pronounced dead shortly after reaching the hospital, the infant was under treatment.

Cruz said the three children and the woman appeared to be related. He noted the woman "initially appears" to be the mother and the man who called 911 was identified as her husband, according to Boston Herald. However, the identities of those involved were not provided by the authorities as an investigation is underway.

"This is an unimaginable senseless tragedy," Cruz said, as per WPRI. "I'm not going to label anybody anything at this time. This is an ongoing investigation."

Officials described the incident as a double death investigation and were in the process of getting search warrants to get back inside the home. He affirmed the investigation is in the preliminary stages and that authorities were closely examining the crime scene. Cruz further confirmed it was an isolated incident and there was no threat to the community.

"These are terrible events and this will be a slow and steady process," Cruz added.
