Police: Pa. Baby Abducted After Grandmother Killed

Investigators did not immediately release details on the death of the girl's grandmother, 61-year-old Satyawathi Venna. Ferman would not say how the woman was killed or whether there were any suspects in the case.

"All of our resources are focused on finding Saavni and reuniting her with her parents," Ferman said in an interview. "The search for the child is intricately connected to the homicide investigation."

Police issued an Amber alert for Saavni Venna on Monday following the discovery of her grandmother's body at the Marquis Apartments in King of Prussia. Later in the night, the girl's father issued a tearful plea for his child's return.

The FBI is assisting in the investigation, said Frank Burton, a spokesman for the agency's Philadelphia office.
