The preliminary investigation report does not contain any
 graphic images, as the police decided to remove
 all attachments (which usually contain photos of the crime scene)
 from the report before releasing it to the public.

 Even then, police are prohibited from including 
 any pictures of dead people due to the law,
 specifically 459/1973, Chapter 5, Section 15
 Here is my poor translation of the first sentence
 "Documents that are about solving a person's cause of death
 are to be kept secret"
 (This law applies for 50 years after the person's death,
 at which point it seems the information is declassified,
 but no cases I've been able to find are old enough.
 Even then, this would probably mean having to order
 the preliminary investigation report again
 from the police to get the version without censors)
