Montville — State police have made an arrest in connection with the December 2017 Griswold fire that killed a husband and wife.

Ruth Correa, 23, of 1630 Main Street, 1002, Hartford, was charged Saturday with three counts of murder, murder with special circumstances, first-degree arson, and first-degree robbery. She is being held on a $2.5 million court-set bond and is due to appear in Norwich Superior Court on Monday.

State police detectives from the Fire and Explosion Investigation Unit and Eastern District Major Crime began investigating.

That same morning, there was an abandoned car fire at 40 Nanel Drive in Glastonbury. Through the course of the initial investigation, state police detectives found that the vehicle was associated with the Griswold house fire.

The next day, on Dec. 21, detectives developed a person of interest in the Griswold fire.

On May 5, at approximately 9:23 a.m., state police from Troop E-Montville responded to the area of Kenwood Road in Griswold after human remains were found in the woods.

Members of the Eastern District Major Crime investigated. The decreased was determined to be Matthew Lindquist, 21, the son of Kenneth and Janet.

On May 11, 2018, EDMC Detectives, with the assistance of the Hartford Police Department, served two search and seizure warrants at addresses in Hartford. Detectives seized numerous items of evidence and conducted several interviews, according to police. Detectives applied for and were granted an arrest warrant for Correa.
