Authorities told WPXI-TV – Pittsburgh that a passer-by saw the child inside the vehicle around 8 p.m. When the witness walked back about 10 minutes later, the child was still inside, so she called 911, police said.

According to police, McFayden told officers she was in a hurry to get to work, and she thought the child had gone back inside her house. She said she got a number of things out of the back seat but never saw her granddaughter.
