PRESTON - Police say a Stonington woman shot and killed her two young grandsons before taking her own life yesterday in Preston.

According to police, 47-year-old Debra Denison, of Stonington, took the boys from their day care facility before killing them.  Police say she later shot herself.

State police issued an Amber Alert for 6-month-old Ashton Perry and 2-year-old Alton Perry yesterday.

Police say they found the children and Denison dead inside a car last night in Preston.

Family members say Denison had a history of mental health issues, but appeared to be fine. They say she wanted to pick up the boys because it was Alton's birthday.
