Officials have announced that the post-mortem examination of French streamer Raphael Graven concluded his death 'was not traumatic in origin'.

The 46-year-old, known online as 'Jean Pormanove', was discovered deceased at a residence in Contes, France, on Monday (18 August) following participation in an online stunt.

In recent times, Graven amassed over one million followers on various streaming platforms, including Kick, and gained a reputation for engaging in perilous challenges.

Reports suggest that the social media personality had previously filmed himself enduring slaps, strangulation, and being force-fed. In another video, he was bombarded with paintball bullets and doused in hazardous liquids.

Graven's final challenge involved streaming live for over 298 hours, during which he received more than £30,000 in donations from viewers, according to The Telegraph.

Subscribers later informed police that they observed the streamer motionless under a bed cover while two individuals - later identified as Owen Cenazandotti and Safine Hamadi, known by the pseudonyms Naruto and Safine - allegedly threw plastic bottles at him.

An autopsy was subsequently ordered by French prosecutors, with the findings disclosed on Thursday (21 August) by Damien Martinelli.

According to the BBC, authorities concluded that Graven's death 'was not traumatic in origin' and 'unrelated to any third-party involvement'.

Martinelli mentioned that 'no internal or external traumatic injuries' or burns were identified.

"The probable causes of death appear to be medical and/or toxicological," the prosecutor added.

Graven's sister had previously spoken out about her brother's 'intolerable' death, suggesting he had succumbed to 'exhaustion' during the live stream.

"I was extremely proud of what my brother achieved," she stated. "I didn't watch everything, but I believe he shouldn't have died like that, that he died of exhaustion. What happened to him is unacceptable."

Naruto and Safine were questioned by police earlier this week, having previously been investigated under a separate inquiry for allegedly exploiting vulnerable individuals for money during online events.

Graven was interviewed by police at that time, but he affirmed that neither Naruto nor Safine had ever caused him harm.

The streamer previously mentioned that such live broadcasts 'were staged and aimed at creating a buzz and generating income'.

A spokesperson for Kick expressed that the streaming platform is 'deeply saddened' by Graven's passing and decided to ban all co-streamers involved in his final broadcast until the investigation concludes.
