PRESTON, Conn. (February 27, 2013)--Connecticut state police Wednesday were calling the shooting deaths of a woman and her two young grandchildren a double murder-suicide.
They say she had permission to pick them up from their daycare.
State police spokesman Lt. J. Paul Vance says Debra Denison, 47, was armed when she left her home Tuesday afternoon in Stonington, Conn., to pick up the children from their daycare.
State police issued an Amber Alert Tuesday evening for Denison, Alton Perry, 2, and his 6-month-old brother, Ashton.
The three bodies were found in a parked car in nearby Preston Tuesday night.
State police believe Denison shot the kids and herself.
The chief medical examiner's office will perform autopsies.
Denison's family said she suffered from bipolar disorder and had a history of mental health problems.
Denison insisted on picking the children up alone despite the objections of their mother, a relative said Wednesday.
Marcia White said the boys' mother, Brenda Perry, asked the grandmother to bring along another relative.
White said Denison's struggles with mental health were well known and Perry told Denison the boys were too much of a handful for her.
White, who’s a paternal great-grandmother of the slain boys, said Wednesday Denison wanted to pick the boys up because it was Alton's birthday.
