I remembered how James and I went to Uncle Mark's old house and the words he said about Frank murdering Mom. I remembered how bad I felt about losing Mom, how supportive Uncle Mark's family was; even how I met Dad again and we came over to his house. How I met Abigail for the first... Abigail! She was the one wearing those same shoes the murderer wore and their body size is almost identical.
I looked away from Antonio, not surprised that everyone else was in the room with us. There was only one person I was interested in... Abigail.
I locked eyes with her, her eyes were watery. What was she crying for? Those tears were definitely fake, she was the one who killed my mother. She robbed James and I of our mother just so she could seduce my Dad and keep him all to herself. It's definitely her; she was the last person that confronted Mom before Mom got in a fight with Frank and the fact that she was wearing the same shoes was no coincidence.
