Prosecutor Frank Middleton said Barry told police that Cyr was reckless in her drug use and that he had seen her snort heroin off a Dr. Seuss book and then leave the book on the floor where the kids could get at it.
Middleton said in court that Barry told police he had made the baby's last bottle by mixing 2 ounces of formula with 2 ounces of water. He said that when Barry was pressed on how the heroin could have gotten into the bottle he said maybe someone had cleaned a dirty syringe in the water bottle he used to make the formula.
Testing determined that the baby formula in the bottle contained heroin. An autopsy determined that the baby died from opiate poisoning.
A grand jury returned manslaughter indictments against Barry, 30, and Cyr, 26, on Thursday. Cyr also was charged with one count of reckless endangerment of a child.
Barry's lawyer, Liam Scully, said that it was unclear who put the heroin in the baby's bottle and that Barry denies any wrongdoing.
"He was devastated by the death of his daughter and is coping with that tragedy the best that he can," Scully said.
