It could be the guy who I often see wandering around the area, especially Ivydale Road. He lives on Ivydale Road and I'm sure he isn't all there mentally, usually a bit drunk/high on something. He was knocking on the doors asking for change a few months ago, I told him where to go and he just left sheepishly. You're right though, she shouldn't have led him to her home. Ivydale and surrounding areas are usually quite safe though, I've walked home late at night countless times with no worries.
