You can come across some pretty disturbing cases in this line of work. Granted, homicide isn't the most pleasant thing to deal with, even when it is routine, but some cases turn your stomach more than others.
One of the tougher cases wasn't even the most difficult to solve. DNA profiling makes things a lot easier now, but to begin with the bodies were difficult to identify.
It became apparent that a spate of killings were sharing a major trait. All the victims had their teeth removed, their genitals mutilated, and their bodies burned. Also, they were all children.
Our killer initially seemed quite particular about avoiding detection, but he hadn't been meticulous enough. He'd failed to wear adequate gloves when removing the children's teeth. His blood was found on the corpses. This seemed to indicate that he had attempted to remove some of their teeth while they were still alive. We can only assume that he was bitten in an attempt to resist.
Eventually, the "Tooth Fairy" was arrested and sentenced to death by lethal injection. I was glad to see him go, but it didn't bring any of the children back, and I still get sick thinking about the case.
