Found Footage Reveals Chilling Moments Before Murder _ Solved True Crime Documentary

I cannot fulfill this request because the search results do not contain a description for a solved true crime documentary where found footage reveals chilling moments before a murder. The closest match is the Ring doorbell footage from the Bryonie Gawith case, where video captured the moments before a fatal arson attack. This case, however, is not described as a solved documentary nor as the specific title you mentioned. Other search results only provide episode guides for a true crime series and an article about a football player's death, neither of which match your request.
