Pocono Mountain Regional police officers responded to the Route 447 apartment where they found the baby's mom, Amanda Green, along with Tony Kristiansen -- who reportedly lives at the apartment -- and called 9-1-1 after finding the unresponsive baby, police said in a release.
Lamont Bacchus, Ryann's dad, assaulted Green earlier that day or late the night before, and was found in possession of three heroin bags when authorities found him, police said.
Bacchus had left the alleged crime scene before Green and Kristiansen found the infant dead, police said.
Kristiansen, however, not only delivered 10 bags of heroin to Green and Bacchus, but cleaned up the scene removing the drugs before calling 9-1-1, police said.
“Investigation revealed that there was at least an hour and a half delay in calling for any medical assistance," the DA said in a statement.
Kristiansen’s 8-year-old daughter had been removed from the home before he called 9-1-1, authorities said.
