The book documents the work of Aftermath Inc., a company that specializes in cleaning up crime and accident scenes after investigations are complete. It traces the history of the company founded by Tim Reifsteck and Chris Wilson in 1996 to fill a need for professional biohazard cleanup required by the EPA. The author embedded himself with Aftermath technicians on over three dozen jobs to observe their work remediating scenes involving violent deaths, suicides, decomposed bodies, and human fluids. Each chapter describes a different type of challenging cleanup situation handled by Aftermath. The book provides insight for those studying forensic science by exposing readers to the realities of crime scene work through the lens of post-investigation cleanup.
