Update 05/20, 9:30 a.m.: The Grant County Sheriff’s Office this morning continues the search for Anthony Mann of Moses Lake.
Mann was last seen around 6:30 a.m. on Friday, May 15, in Moses Lake. His unoccupied van was reported around 6 p.m. Monday, May 18, near Trail Lake in rural Grant County, about five miles south of Coulee City. Nearby campers called 9-1-1, concerned that the van had not moved over the weekend. Deputies searched the immediate area and did not find any sign of Mann.
Search efforts continued on Tuesday morning. Teams flew drones, drove off-road vehicles, and rode on horseback. Search efforts were paused around 6 p.m. Tuesday.
This investigation is being referred to the Major Crimes Unit to look into where Mann may have been after he was last seen on Friday morning. They will also attempt to get data from Mann’s cell phone, which was found inside the van.
Searchers will continue their efforts today. A large area was covered yesterday. Nearby hazards include Trail Lake as well as an irrigation canal.
We understand the public’s desire to help, and the offers are greatly appreciated. However, there is currently no request for the public’s help in searching the area.
We still need the public’s help with learning where Mann went after he was last seen on Friday morning. If you have information that could help us, please call 509-762-1160.
