Fitness influencer Chris O’Donnell, who boasted more than 840,000 followers on social media, died on Saturday at age 31.

The content creator’s death was confirmed in an online obituary.

The obituary didn’t reveal O’Donnell’s cause of death, but the Maricopa Medical Examiner confirmed to People that the social media star died from a gunshot wound to the head.

His death was ruled a suicide.

O’Donnell, known to fans online as Creeohdee, boasted nearly a million followers on his TikTok platform and racked up over 28 million likes through his inspirational workout videos.

On Instagram, he had more than 240,000 loyal followers.

The social media star’s final post on TikTok was a video of him giving a heartfelt speech at his brother’s wedding.

In the clip, which has since been made private in the wake of his death, O’Donnell said he was “reminiscing on old memories” and felt compelled to share the sweet moment.

“One of my proudest moments as a brother, being able to send these two off into the next chapter of their lives,” he said of the 7-minute video.

O’Donnell was less active on Instagram, with his final post being in Nov. 2024.

The eerie final post was an Instagram reel showcasing his recent hiking trips.

“I wonder when I leave this earth, when I leave the rat race, when I’m lying in the dirt, if you’d remember my face,” he captioned the clip.

“I am a content creator with most of my media revolving around fitness. However, fitness is far from my passion,” he said in a separate Instagram post shared in Dec. 2022.

Before his untimely death, the fitness guru described himself as a “very solitary person,” and often shared his mental health struggles with fans to “help others along their own path.”

He was also outspoken about the “many different walks of life,” telling his followers that he loved “learning about other cultures and beliefs that make me challenge my own.”

“I also got sober in 2018 and have been an advocate for substance abuse awareness ever since, helping men and women who are struggling find the treatment they need,” he previously wrote on social media.
