11-month-old Dominic Dickinson died on May 13th after ingesting his parents’ heroin and fentanyl; the latter, a powerful painkiller.

Paramedics had received a call about a baby not breathing in Columbus, Ohio. He had turned purple by the time they arrived.

At first, authorities weren’t entirely sure that drugs were the culprit. Young Dominic had been found in his playpen surrounded by his blankets. This, to investigators, at least opened up the possibility of SIDS, or Sudden Infant Death Syndrome.

Although drug paraphernalia was found at the home, it couldn’t immediately be tied into the tragedy. It wasn’t until toxicology reports came back that it was determined. What remained undetermined, however, was whether or not the small child had been given the drugs or if he’d somehow gotten into them on his own.

On Tuesday, it was announced that a grand jury returned indictments on the child’s parents, 29-year-old Kyle Black and 32-year-old Denise Dickinson, on charges of involuntary manslaughter and child endangering.

They face up to 11 years if convicted.
