“He never left the block so he would literally just come through the alleyway, down Bristol, to L, up L, back to Hunting Park and he would just circle,” Gianna Cianci said.

The suspect is described as a man with a light complexion. He was wearing a red hooded sweatshirt, gray shorts and red athletic shoes.
