Redditor _ValiumKnight__**_got the ball rolling with the following question, which immediately led me down the Ask Reddit rabbit hole:
Detectives/Police Officers of Reddit, what case did you not care to find the answer? Why?
Law enforcement professionals chimed in immediately to speak about some of their more unnerving cases.
Police work is not easy----and some cases are harder than others.
I had been alerted to a well known local philanthropist, turned up dead. These were the days where physician assisted euthanasia was illegal in most of the developed world. This man, I had known him quite well and he had been suffering from a very serious terminal illness that was going to kill him before his 40th birthday, shattering his family... Especially his 2 young children. He was always donating to local charities, he gave a struggling single mother $25,000 at Christmas one year so she could pay off her debts, repair her car, buy food and presents for her children. An autopsy had determined that he had been murdered, an intentional overdose of morphine. The Health Authority and Department of Justice wanted us to investigate and bring the person who essentially murdered him to justice. We chalked it up that there was no way we could ever determine who it was that killed him. Years later, his wife sent our department a letter saying she gave her husband the lethal dose to put him out of his misery. I wish I had never known.
Child porn is the worst in general. It's one of those things where you want the bad guy to go away, but you really don't care to find the evidence.
