A tragic waterfall accident has led to the death of three popular travel vloggers. ‘High on Life’ YouTube stars Ryker Gamble, Alexey Lyakh and Lyakh’s girlfriend, Megan Scraper, were killed Tuesday as they were on their latest adventure in Canada. Reports say the trio was at the top pool of Shannon Falls in British Columbia when Scraper slipped and fell. The three were then swept by the current and plummeted about 100 feet into the waterfall’s lower pool. All three were killed in the fall.
