A family of five, including 9-year-old twins and an 11-year-old girl, has been found dead in a two-story condominium in Massachusetts, police said.
A member of the family called 911 regarding a "medical emergency" at 135 Center Ave. in Abington, Plymouth County, around 7:30 a.m. on Monday, District Attorney Tim Cruz said during a news conference.
The relative had gone to the house to help get the three children to school, he said.
"This is just a horrible, horrible event here for the town of Abington and for the children and the schools," Cruz said.
