Three YouTube stars died Tuesday after they fell over a Canadian waterfall. Ryker Gamble, Alexey Lyakh, and Megan Scraper were swimming at Shannon Falls when Scraper fell and Gamble and Lyakh tried to save her. Police said they fell about 98 feet. Gamble, Lyakh, and Scraper were part of High on Life, a travel YouTube channel that has over 500,000 YouTube subscribers and 1.1 million Instagram followers. “They were three of the warmest, kindest and most driven and outgoing people you could ever meet,” said a group member in a video posted to the YouTube channel. A memorial GoFundMe page has been set up in their honor.
