Synopsis: Closure

I have two plots running in my head I'm not sure if I'll combine them or not...
First, a lonely man seeking his passion of photography also aches for closure for the sudden death of his wife. He finds company with another person that becomes his best friend but are friends deceiving?

A police lieutenant has accomplished a great deal in his few years at the department. He is friends with the entire force and is a devoted officer and a well loved citizen in his town. Since he divorced last year, he continued to live and breathe work. The sudden disappearance of his childhood friend always was unsettling to him as many of his friends helped him find closure but there was no sign of her after that one chilly night so many years ago. He found his passion in solving missing person’s files within his department. Unfortunately most of those missing persons he finds are found dead. Is there a reason why he is able to close so many files and give everyone closure in his city?
