A Suffolk woman was sentenced Monday to seven and a half years in prison for charges stemming from her granddaughter’s death.

Kimberly Denise Artis, 40, pleaded guilty to charges of involuntary manslaughter, child abuse with serious injury, possession of a controlled substance and conspiracy to possess a controlled substance in October.

Two-year-old Destiny Riddick died on July 17, 2011, after ingesting suboxone pills that had been purchased on the street and were kept in a Mentos candy container that had been placed under a pillow in the master bedroom, prosecutors have said.

Suboxone is a prescription drug used to treat opiate dependence.

Police and rescue personnel were summoned to the 1100 block of Truman Road that day because the girl was not breathing. She was pronounced dead shortly after her arrival at the hospital.

The child’s grandfather, Steven Wade Bullock, 51, was sentenced in December to seven years and nine months for the same charges, as well as a charge of possession of marijuana.
