Provincial police say the search for a missing person from Bracebridge has turned into something sinister. On Wednesday, OPP announced the disappearance of 38-year-old Daniel Holden is being treated as a homicide investigation. Holden has been missing since Sept. of 2023. Police initially believed Holden was in the area of Southwood Road in Gravenhurst on Saturday, August 12, 2023. Further investigation revealed Holden was identified on surveillance footage at an Esso gas station on Ecclestone Drive in Bracebridge on that same day. In late October, OPP put out surveillance footage of Holden at the gas station. In the video Holden is seen with another man, whose identity was unknown to police. At the time, police believed foul play to be a factor in Holden’s disappearance. OPP asked the public to help identity the second male in the video, suggesting he may be the last person to see Holden before he went missing. In the press release, police said a search warrant was executed at a home on Southwood Road in Killworthy on Nov. 6. Though details about the warrant are scarce, police say residents should expect to see increased police presence in the area. Anyone with information in relation to this investigation is asked to contact the Bracebridge OPP.
