Not everyone has jobs they're proud of, and even fewer have occupations that make people want to vomit during introductions. Businesses like Murder Scene Mop Up - actually named Advanced Bio-Treatment - certainly aren't for the faint at heart, but it's a disgusting job and someone's got to do it.
Proving that there truly is a business to cover every obscure niche market is Murder Scene Mop Up, a business that specializes in crime scene cleanup after the CSI types are finished with their detecting. It's the part of the job that's ever shown on TV, but someone's got to clean up a murder scene before the house can go up for sale, or family members return home. They do deal with cleanup of locations for more than just murder of course, but the other aspects of the job just aren't any prettier when they're dealing with the cleanup of meth labs, biohazards and anything else that might just be too disgusting to talk about.
Because you just can't control when someone might be killed, or when a meth lab is raided by the police, Advanced Bio-Treatment provides emergency services 24/7. It's a gory business, but someone's got to do it.
