The human body starts to decay rapidly, and then there are wild animals. The body turns black if it isn't embalmed, there is coloring added to the fluid. The body will also swell in any conditions from internal gases, and in extreme cases can actually split the skin. If it has been in the sun and they have had warmer than normal temps, the it makes the process even faster. And it has been a month or more.
