Authorities have not ruled out the possibility that more bodies may be inside.
Worcester County District Attorney Joseph Early Jr. said the house was in “deplorable condition.” Authorities don’t know when or how the babies died, or their ages and genders.
No criminal charges have been filed in connection with the deaths, but police say a woman who lives at the home of 23 St. Paul St., was arrested on charges related to the living conditions at the house.
Erika Murray, 31, would be arraigned Friday.
Four other children, including a 6-month-old, a 3-year-old, a 10-year-old and a 13-year-old, were removed from the house last month after a neighbor notified police about their living conditions. Those children are in state custody.
Investigators are expected to be at the home throughout the next few days.
Crews entering the home have had to wear protective clothing and protective gear, and a decontamination process has been set up for crews leaving the home.
“The house is filled with vermin,” Early said. “We have flies. We have bugs. We have used diapers, in some areas, as much as a foot-and-a-half to two-feet high. The house is in a deplorable condition.”
The remains of several cats and a dog were also found inside the home, officials said.
Neighbors said the smell coming from the home was sickening.
