Javan and her team took samples of liver, spleen, brain, heart, and blood from 11 cadavers, at between 20 and 240 hours after death, then used two different state-of-the-art DNA sequencing technologies, combined with bioinformatics, to analyse and compare the bacterial content of each sample.

This usually begins in the liver, which is enriched in enzymes, and in the brain, which has high water content; eventually, though, all other tissues and organs begin to break down in this way. Throughout this stage certain early post-mortem indicators may begin to occur, such as livor mortis (pooling of blood in the body), rigor mortis (stiffening of muscles) and algor mortis (body temperature reduction). Having been raised in a family-run funeral home in north Texas, and worked there all her life, she has seen and handled dead bodies on an almost daily basis since her childhood.
