The 29-year-old became known on the video site for playing and criticizing Nintendo games.
New York police said that he disappeared after having a telephone conversation at 8:00 pm on June 19.
Police had launched a public appeal on social media with his photo in an effort to locate Amofah, a resident of New York’s Brooklyn borough.
After recovering the body, which was pronounced dead at the scene, they began an investigation and later identified the victim as Amofah.
Social media “can give you an image of what you want your life to be and get blown completely out of proportion,” he says in the video. “It consumed me.”
The video was later removed by YouTube for violating the platform’s rules, but many users shared it.
