GRISWOLD, Conn. — Connecticut State Police have identified the two people killed in a house fire in Griswold as a husband and wife.

Police say 61-year-old Janet Lindquist and 56-year-old Kenneth Lindquist were the owners of the home where they were found dead on Dec. 20.

Investigators haven’t made any arrests but say they do have a person of interest in the case. State Police identified the person of interest Thursday as Matthew Lindquist, the son of the victims, and say they’re looking for him.

Griswold Volunteer Fire Chief Tom Holowaty had told WVIT-TV that a third adult also lived at the house.

Police are investigating a link to a burning car found in Glastonbury the same day as the house fire. The Hartford Courant reports the car was registered to the Lindquists.
