“Out, Damned Spot”: The art and science of forensic restoration

Abstract

Forensic restoration focuses on remediation of indoor environments that are contaminated with potentially hazardous biological materials. Some of the more challenging cases are those where someone has died alone and remained undiscovered for some time. Decomposition begins almost immediately after death: blood stops circulating and starts to pool and coagulate, and cells undergo autolysis. Our commensal microbes, critical to health during life, turn against us after death and start consuming us from within. Anaerobic microbial processes produce odorous volatile organic compounds and fluids that seep into the floor. Insects can oviposit in the body, resulting in masses of larvae feeding on the body. When ready to pupate, larvae leave, acting as vectors which can spread contamination around the site. Remediating a home where an unattended death has occurred involves removal of fluid-soaked items and a load reduction to remove soil, followed by a thorough cleaning to remove organic materials and prepare surfaces for disinfection, all while keeping operators safe from potential infectious agents. It’s certainly not a job for everyone, but one couple is trying to bring a higher level of science-based practices and training to the industry.
