A couple accused of killing their 5-month-old daughter by giving her a bottle of formula with heroin in it have been charged with manslaughter.
Ryan Barry and Ashley Cyr were arrested on Friday (local time). They pleaded not guilty and were ordered held on $200,000 cash bail.
The couple's daughter Mya Barry died in September 2011, when the family lived in Marshfield, a half-hour drive southeast of Quincy.
Police responded to an emergency call and found the baby on the living room floor with her grandmother performing CPR on her, Plymouth County District Attorney Tim Cruz's office said. The baby was pronounced dead at a hospital a short time later.
Police said they found 3 grams of heroin and hypodermic needles on a shelf in a bedroom shared by Barry, Cyr, the baby and her two sisters, ages 3 and 4.
