The difference between homicide and suicide is that in homicide, a person kills another person either on accident or on purpose, while suicide is when a person takes their own life.
A body can provide a lot of evidence to an investigator.

The body temperature of the liver can tell the time of death, the level of rigor and decomposition can also give clues to how long the body has been dead as well.
Modus Operandi is used to find clues to the perpetrator’s personality. It gives the...
