Two-year-old Alton Perry was fatally shot in the head by his grandmother, Debra Denison, and his 6-month-old brother Ashton died of multiple gunshot wounds, according to the state Office of the Chief Medical Examiner.
WTNH-TV reports that both boys' deaths were ruled homicide. Debra Denison's death was ruled suicide, as she died of a single gunshot wound to the head.
Denison picked up both boys at their North Stonington day care on Tuesday — Alton's second birthday — and when she failed to bring the boys home an Amber Alert was issued. Police said a suicide note had been found and Denison was carrying a handgun.
