According to a criminal complaint, paramedics and police were called to Robinson’s home around 9:25 p.m. Wednesday. They found the child unresponsive.
Investigators said Robinson pushed Amy down the stairs after she became angry with the victim and hit her, WCAU reported. She then allegedly called a friend and told her, "I knocked Amy out. ... She won't wake up. ... I am going to jail."
Robinson also has a 2-year-old son. He did not show any signs of harm and was taken into protective custody by the county, Hogan told WTXF.
