Finish the following prompt in under 300 words but make it in the style of a mystery: "He hadn't seen the old man since..."
gpt
He hadn't seen the old man since his mother's funeral five years ago. 

Just as he did back then, the old man sat in the back pew of the church. The man was dressed entirely in black, suitable attire for Mary's funeral, and held a large black suitcase in his hands. As the pastor droned on in his Sermon about the shortness of life and the forgiveness of God, the old man barely seemed to move. 

Jake turned back around to face the front, dismissing the old man, his eyes lingering on the framed photo of his sister next to her closed casket. It was dreadful enough to have to bury your sister when she was only 35 but for her to have died in such a manner - shivers crept up his spine and he gave a slight shrug to hide it. 

The detective sitting next to him gave him a sideways look. Matthew had been the one to suggest that his sister's killer may make a reappearance at the public funeral and volunteered to sit beside Jake during the ceremony. Cameras had been placed strategically around the church in an attempt to capture the image of everyone in attendance. 

Later, Jake would wonder if he had imagined the old man -- if he had been a coping mechanism of sorts that began with his mother's similarly traumatizing murder those five years ago because as Matthew reviewed the camera footage from the funeral, there was no capture of that man at all.
