A newspaper article found in the labyrinth reveals that Thomas was murdered between the time of 11:00 P.M. and 12:30 A.M., date unknown. Angela was the murderer, who stabbed him multiple times in a fit of passion with a knife.
A photo left in a room in which Angela was residing shows a mother, daughter, father and son in that order. The photo is torn in half between the father and daughter. This could have been done by Angela, showing that the abuse happened when she was young.
In the creased photo, the father appears to look young himself, wearing a checkered shirt. He has what looks to be a five o'clock shadow and short brown hair, while Thomas' eye color is not clear. It is possibe that the creased form of the photo symbolises Angela's view on her family as "broken".
