"Earlier today I was informed by the West Brookfield police of a tragedy involving two West Brookfield Elementary School students. The specific circumstances are unknown at this time," Superintendent Brett Kustigian said.
School will be in session Friday, although added security and grief counselors will be at the school for the day.
Early said officers then got a search warrant for the home before beginning their investigation.
While police said the deaths are being treated as suspicious, the West Brookfield police chief said there is no reason to believe the public is in danger.
“It’s very early in the investigation we can’t give you anything more than that right now. Literally our specialists are getting in the house now, we’ve got to let them do their jobs,” he said.
These four deaths have not yet been ruled homicides, but district attorney Early said that is part of the investigation.
