Ex­perimental study and practice on the detection of vegetative planktons in the bone marrow of the drowned dead body

Experiment on the animals proved that in the case of the death by drowning planktons always immigrate into the bone marrow and some kinds of them can be detected in the bone marrow even after a long period of time, suggesting that the detection of these planktons in the bone marrow of the dead person will give the important clue for the determination of the cause of death by drowning. Actually applying this method in a decayed corpse, we could successfully show the cause of death is due to drowning in which the cause of death was long argued in the court.
