Some years ago a woman was found dead in her husband’s factory, with multiple head
injuries. The crime scene showed a lot of blood stains, different in form and dimension.
The woman’s husband was the first and only suspect of the murder. He was the first to
reach the crime scene and a lot of blood was found on his clothes, while his shoes were
clean. The suspect said he was dirty because of having trampled on the bloody floor
and also because of having touched his wife’s bloody body. An analysis of the blood
stains on the man’s clothes and their compatibility with the dynamic of the murder
were requested by the judge during the trial. The possibility for the suspect of making
himself dirty by embracing the dead corpse and/or by trampling the blood on the floor
was investigated. The collected data were very useful for providing valuable information
for the accurate reconstruction of the crime history
