Police have now arrested both suspects wanted in connection with the death of their 2-year-old granddaughter last year.

Kimberly Artis, 39, turned herself in about 1:30 a.m. Sunday, city spokeswoman Debbie George said.

Steven Bullock, 51, had been arrested at a residence in Portsmouth about 4 a.m. Saturday, based on a tip.

According to a Suffolk press release, police and rescue personnel on July 17, 2011, were called to a residence in the 1100 block of Truman Road in reference to a child not breathing. They found 2-year-old Destiny Riddick unresponsive and transported her to Sentara Obici Hospital, where she was pronounced dead shortly after her arrival.

According to the press release, investigation has revealed that the child had ingested suboxone, which is a prescription drug used to treat opiate dependence, according to the U.S. Food and Drug Administration.

The drug allegedly was kept in a candy dish in the home, the news release said.

Both suspects are charged with felony murder/homicide, felony abuse or neglect of a child, possession of a Schedule III drug, and conspiracy to possess a Schedule III drug. Bullock also is charged with second offense possession of marijuana.
