New London — An ex-con from Hartford charged in the grisly murders of three Griswold family members has yet to decide whether to pursue a probable cause hearing.

Sergio Correa, 27, made a brief appearance before Judge Hillary B. Strackbein in New London Superior Court on Friday where his case was continued to Nov. 9. He appeared with one of his attorneys, Michael W. Brown.

Correa agreed to continue to waive the time requirements for the state to hold a probable cause hearing. The hearing, if he decides he wants one, would involve presentation of the state’s case against Correa and a decision by a judge on whether there is enough evidence to move the case forward.

No hearing has been scheduled and Correa has yet to enter a plea.

Correa and his adopted sister, Ruth Correa, 23, are facing multiple felony charges in the December 2017 killings of Kenneth and Janet Lindquist and their 21-year-old son, Matthew Lindquist.

Police allege Matthew Lindquist made a deal with Sergio Correa to allow the burglary of his home and theft of guns in exchange for drugs. Instead, police allege, the brother and sister stabbed Matthew Lindquist to death, left his body in the woods and proceeded to kill his parents and burglarize and burn the Lindquist home.

Ruth Correa has already confessed to her participation in the crime, police said. Details of the meeting with Matthew Lindquist and the subsequent killings were revealed in the arrest warrant affidavit previously unsealed in the case. The affidavit in the Sergio Correa case was unsealed Friday.

Investigators discovered the parents’ bodies amid the burned remains of their home at 70 Kenwood Drive in Griswold on Dec. 20, 2017. They had been severely beaten and the cause of death was ruled “homicidal violence,” with associated head injuries, according to results of an autopsy performed at the Office of the Chief Medical Examiner. The report also showed that in addition to head wounds, burns and smoke inhalation contributed to Janet Lindquist’s death.

Matthew Lindquist’s body was discovered on May 5 in the woods about 1,500 feet from the Lindquist residence. He died of multiple stab wounds to the head, torso and extremities.

Matthew Lindquist, whose family said had recently relapsed into an illegal and prescription drug addiction, had allegedly planned the burglary of his home with Sergio Correa — whose felony criminal record includes multiple counts of first-degree assault and first-degree robbery, along with larceny, arson and gun possession charges. Sergio Correa was on probation at the time and had served a 10-year sentence for previous crimes.

Sergio Correa remains held in lieu of more than $3 million in court-set bonds. The charges against him include three counts of felony murder, first-degree robbery, first-degree arson and home invasion.

Ruth Correa, who faces similar charges, remains held in lieu of a $2.5 million bond and is due back in court on Dec. 5.
