The west parking lot and trail entrance to Nose Hill Park are closed this weekend as police continue to search for missing 11-year-old Parker Wells. Police said in a Saturday morning release that the parking lot and pathway entrance off Shaganappi Trail N.W. will be closed throughout the weekend. “The closure will allow search teams to safely and efficiently conduct operations in the area,” police said. They added that “the closure should not be interpreted as an indication that Parker has been located or that investigators have information placing him in this area.” Police ask that residents use alternate park access points and avoid the area where police and its partners are searching. Search enters day 10 Parker disappeared from his day home in the 0 to 100 block of Connaught Drive N.W. on July 16 sometime between 11:08 a.m. and 11:41 a.m. Police say CCTV footage later confirmed his movements before he was last seen at 12:52 p.m. in the area of Travis Crescent N.E. Since then, the investigation has expanded into one of the largest missing-person searches Calgary has seen in recent years. Police say investigators have followed up on more than 400 tips and reviewed more than 1,000 CCTV video clips. Trained search teams, patrol officers, the HAWCS helicopter, drones equipped with thermal imaging, mounted officers, police dogs and Calgary Fire Department crews have also searched parks, waterways, storm infrastructure and green spaces across the city. Earlier this week, police renewed calls for homeowners, landlords, Realtors and property managers to repeatedly search homes, garages, sheds, trailers, RVs and vacant properties, particularly along Travis Street, Travis Crescent, Trelle Drive, Taylor Crescent, Travis Place and Thomas Street N.E. Investigators say Parker has a history of entering accessible structures and locking doors behind him, raising concerns he could be sheltering inside a building that has not yet been checked. Acting Staff Sgt. Scott Guterson said earlier this week that police won’t rest until they find answers. “We remain relentless in our commitment to finding answers to the question we are all asking: where is Parker?” Guterson said. “While there may come a time when all realistic search avenues have been exhausted, we will not give up, and we will continue the missing person investigation for as long as it takes.” With files from CTV News’ Mark Villani
