In little more than a year after Reta Mays started work as a nurse's assistant in the VA centre, there were 21 suspicious deaths. The FBI launched an investigation, leading to the exhumation of some of her victims.

Dr Bob Neulander found his wife, Leslie, covered in blood in the bathroom, having apparently fallen. Initially, her death was ruled an accident, but due to local rumours the DA reopened the investigation.

Over the course of just a few months, Vickie Jackson murdered at least ten people. An investigation found a suspicious syringe in Jackson's trash, and bodies were exhumed to test for the lethal drug.
