~20:45: Wallace is heard knocking on his back kitchen door by neighbour Florence Johnston.
20:45+: Florence and John Sharpe Johnston leave the back of their house and yard and as they are leaving see Wallace coming back round from the front. He asks if they have heard anything unusual to which they reply no.
He explains the doors are shut against him.
John Sharpe Johnston suggests trying again and if the door still will not open he’ll get his spare key.
The door now opens and Wallace enters. The Johnstons claim they suggested waiting outside, Wallace claims he asked them to wait.
Wallace is heard to head upstairs and calls out what appears to be a name.
About 1 or 2 minutes after the lights go on upstairs Wallace rushes outside exclaiming something like: “Come and see, she’s killed!”
Mrs. Johnston feels Julia’s hand when John asks if she’s cold. She is still warm. Wallace suggests John go for the police and a doctor. They all return to the living kitchen (where the cash box is kept). Wallace points out a cabinet door which has been wrenched off. Mr. Johnston asks if anything is missing and Wallace takes down the cash box, opens it, and says about £4.
Mr. or Mrs. Johnston ask him to check upstairs to make sure everything is alright up there before John goes for the police.
