Kitty was attacked for the second time in a small vestibule inside a doorway in the rear of the 2 story Tudor building shown here. Although blocked from view, the doorway is just to the right of the mailbox shown in the inset.
The one witness to the second attack on Kitty was 31 year old Karl Ross, whose apartment was one flight up from the small vestibule in which attack took place. According to former Chief of Detectives, Albert A. Seedman, "Rather than take the stairs and confront the horror in the vestibule, [Ross] hoisted himself out his window and scooted across the steep Tudor roof to [another apartment]." Given the steep incline of the roof, the lack of anything to grab onto, and the absence of a fire escape, I am unable to figure out how Ross - a dog groomer by profession - was able to do that without falling to his death. It is especially puzzling because Ross was reported to be intoxicated at the time.
