Amber Alert Ends in Tragedy: Stonington Woman Kills Two Grandchildren & Herself

Last night's Amber Alert ended tragically when a 47-year-old Stonington woman took her 2-year-old and 6-month-old grandsons from their day care provider Tuesday, drove to Foxwoods and shot and killed the children with a .38-caliber handgun before turning the gun on herself, according to Connecticut State Police.

At 7:45 p.m. Tuesday, state police issued an Amber Alert after receiving a call from the mother of the children. Police confirmed for Patch later Tuesday evening that Debra Denison, the boys' grandmother, picked up the baby and toddler in Danielson and drove off with the children and the gun in a 2002 White Chrysler Town & Country minivan with a CT registration of 445-ZAZ. In the Amber Alert, state police said Denison is "bipolar and has medical conditions."

State police troopers and detectives were called in to work the investigation, and area police agencies were notified and given the descriptions of Denison and the children, 6-month-old Ashton Perry and 2-year-old Alton Perry. State police at Troop E in Montville confirmed that Denison had left a suicide note.

At about 9:30 p.m., according to a press release issued late Tuesday by state police, Troop E received a 911 call that a vehicle with three injured people inside — two of them children — was found parked near Lake of Isles.

According to the release, troopers and local EMS personnel responded to the scene and confirmed the vehicle matched the one in the Amber Alert. Denison and the two children were pronounced dead at the scene.

The Day and WFSB-3 are reporting that Tuesday was Alton Perry's second birthday.

Late Tuesday night, state police continued to block the entrance to Lake of Isles Road, and the Eastern District Major Crime Squad responded to the scene to investigate. The Office of the Chief State's Medical Examiner will conduct an examination to determine the cause and manner of death.

At Debra Denison's Sherwood Drive home in Stonington late Tuesday, the house was dark except for a solitary lamp lit in the living room. No one answered the door.

Early Wednesday along Norwich-Westerly Road (Route 2) in North Stonington, a state police cruiser blocked the driveway of a home with all its lights on and several cars parked in the yard.

According to the Connecticut Judiciary website, Denison has a criminal conviction for reckless driving from 2003 but no other Connecticut police record. 

Numerous attempts to reach Connecticut State Police spokesman Lt. J. Paul Vance for additional details were unsuccessful.
