Alton Dennison, Ashton Denison

A grandmother and her two grandchildren have been found dead in Connecticut after an alleged murder-suicide.

FOX News Radio's Courtney Kealy reports:

47-year-old Debra Denison and her two young grandsons were found dead in a parked vehicle according to authorities in Connecticut.

Denison allegedly took the two boys, six-month-old Ashton and two-year-old Alton Perry from their daycare and police issued an amber alert after receiving a call from the boys' mother.

According to Connecticut State Police, Denison drove to a local golf course where she used a .38-caliber handgun to shoot and kill her grandsons and then herself.

The family says Denison has a history of mental illness and suffered from bipolar disorder.
