"The Staten Island teenager who was baby-sitting her boyfriend's 2-year-old son when he died was arrested Thursday - and the child's father also could face charges, police sources said.
Dubois, 18, admitted she shook Josiah but claims she did so only after the child stopped breathing, police said.
The city medical examiner ruled Josiah's death a homicide. Dubois, who was initially arrested for endangering the welfare of a child, could face additional charges, the police sources said.
The autopsy also revealed that Josiah had suffered injuries over an extended period of time.
Dubois blamed the boy's father, her boyfriend, whom she claimed had been beating the child, the sources said. Police were questioning the dad, 28-year-old Darrell Taylor, late yesterday.
Taylor told cops he was at work when the toddler lost consciousness, but investigators are trying to determine whether he - or another adult - previously injured the child, the sources said.
Dubois is to be arraigned today in Staten Island Criminal Court."
