The district attorney in Berkshire County said a house fire Wednesday morning in Sheffield, Massachusetts, was the scene of a murder-suicide that left a family of five dead.
DA Andrea Harrington offered the new information during a press conference Thursday.
"Among the deceased were Luke Karpinski and his wife, Justine Wilbur, both 41, who lived in the home with their three-year-old and seven-year-old twins," Harrington said. “We are investigating this matter as a murder-suicide. At this time, the evidence indicates that Luke Karpinski was the assailant."
"I can tell you that the mother was found individually, and the four other individuals were found upstairs," Harrinton said.
Harrington said the bodies were transported to the chief medical examiner's office in Boston for autopsies.
"This is a comprehensive and ongoing investigation," she said. "We will provide information as soon as we're able to."
Harrington said investigators from the state police and fire marshal's office continue to comb through the scene.
