[6 cases of premeditated murder of adults by drowning].

Premeditated murder of adults by drowning is rare and hard to investigate. Six cases are reported. If the aim of the killer is homicide by drowning to begin with (primary drowning), it is usually difficult to prove as morphological findings are missing of may be insignificant and ambiguous. If, on the other hand, the killer opts for drowning only as a conclusion to a primarily differently planned assault (e.g. strangling), the finding patterns are different, and their interpretation is usually easier (secondary drowning).
