"Body found 15 minutes into sweep of river for missing persons" "While neither police nor RCMP were working to locate anyone specific, city cops currently have 86 historical files of missing persons dating back to the early 1970s. Alberta RCMP have 36 cases of missing persons from communities near the river, four of whom are known to have entered the river area before disappearing. One such case is Dylan Koshman, just 21 years old when he went missing from his southside apartment Oct. 11, 2008, after arguing with his cousin. Another is Shelly Dene, who was 26 when her family lost contact with her last November. "Someone, somewhere, knows something about my sister's whereabouts," Candice Lhommecourt said at an awareness walk organized by Dene's family in June. The Edmonton search, including three boats and the Air-1 cop chopper, for human remains started at the boat launch near the EPCOR Water treatment facility and fanned out east and west."
