Is there any record in the historical materials that he choked to death because of saliva?

A Frenchman tried a complicated suicide on 1998. He stood on a high cliff, put a lasso around his neck and fixed the rope on a huge rock. Then he drank the poison and began to set himself on fire. When he jumped off the cliff, he shot himself again. As a result, the bullet didn't hit the target, but passed through the rope, so he fell into the sea and couldn't hang himself. The cold sea water put out the flame on his clothes, and the impact made him spit out poison. A fisherman dragged him out of the water and took him to the hospital. As a result, he couldn't swallow saliva because of his cough and died.

I don't know if this is a joke or a real case. But don't worry, no one can choke on their own saliva.
