Yes i remember watching a man being interviewed on the news awhile back and
he spoke about the screams that sent shivers down his spine..will thats what he meant.
The time of him hearing the screams will give the police a good indication of when Allison
was not at her home.
I think their was also another neighbour who heard screams as well if i remember correctly.
Anyway i shall be back as usual to see if you have found more info.
