Post-mortems in France have explained the mystery of how two men found dead together after a meal perished, reports BBC News.
Lucien Pérot, 69, who had been drinking, choked on a 44g (1.5oz) beef rib he could not chew, reportedly because he had several teeth missing.
Olivier Boudin, 38, who had a pre-existing genetic heart condition, had a heart attack seeing his friend die.
There had been intense speculation over what had happened after their bodies were discovered last Thursday.
The men had been sharing a meal in Perot's garden in Authon-du-Perche, south-west of Paris, and drinking heavily. Pérot was found to have 2.4g/l of alcohol in his blood.
One was found sitting on a chair and the other lying down, prosecutors said.
The two men had grown close and developed a "father-son" relationship, local residents said.
Many were relieved to discover that they had died of natural causes, reports said.
