The bodies of two children were found inside a Massachusetts home Tuesday evening. Authorities investigating the incident said that there were three children under the age of six at the home in Duxbury.

First responders arrived at the home at 47 Summer Street after receiving a 911 call from a male resident, Plymouth County District Attorney Tim Cruz said. A 5-year-old girl and a 3-year-old boy, who police say had obvious signs of trauma, were declared dead at the hospital. An 8-month-old boy was flown to a Boston hospital for emergency treatment.

The incident came to light when the male resident reported the attempted suicide of an adult female resident. The woman reportedly jumped out of a window in the home.

“This is an unimaginable, senseless tragedy, and it is an ongoing investigation,” Cruz said.

While the woman has not been identified as of Wednesday morning, Cruz said that she is the mother of the three victims. Officials are not releasing the identities at this time.

“It’s an ongoing investigation and we will see where that leads us,” Cruz said. “We’re in the process right now of getting information regarding our search warrants, making sure we do everything we need to do to get into the house lawfully to make the determinations that we have to make.”

It remains unclear if the woman is the suspect in the case.

This is a developing story.
