Police said photographs and videos circulating online appeared to show a man spray-painting a red message onto boulders in the area.According to RCMP, the graffiti appeared to be an attempt to memorialize a man who drowned near the falls on August 3.“While this incident appears to be an attempt at memorializing a drowning victim in the area, vandalism within a protected area is still considered a criminal offence,” Maple Ridge RCMP said.Police said the graffiti could harm the environment, diminish the experience of other park users and create cleanup costs for the community.The investigation later resulted in an arrest after the alleged suspect turned himself in. RCMP said he was released on a promise to appear in court while investigators continued gathering evidence and working with BC Parks..As of now, it remains unclear when the markings near Devil’s Thumb were made, how extensive they are or whether Parks Canada has identified anyone responsible.The Western Standard has reached out to Parks Canada for comment on the markings, whether officials are investigating, and what penalties could apply to those responsible.
