AIRDRIE — Police say a man who was questioned in connection with the disappearance of a five-year-old Calgary boy and his grandparents has been released.
Calgary police say he remains a “person of interest” and several police units will continue to search a residence connected to him on the outskirts of Airdrie, northeast of Calgary.
Investigators say that, given the size of the property, the search is likely to continue throughout Sunday and into Monday as they search for clues in the disappearance a week ago of Nathan O’Brien and his grandparents — Alvin and Kathy Liknes.
Acting on a tip police arrived at the property late Friday night and found a green Ford F-150 truck similar to one spotted in a video taken near the Liknes home.
Police say they are trying determine if the truck, the property, or the man taken in for questioning, are linked to the investigation.
Nathan and his grandparents disappeared on Monday after the couple held an estate sale, and police have said there was evidence of a violent incident in the Liknes’s home.
Police say they want to hear from anyone who has any information regarding the whereabouts of the missing people or recognizes the pickup that was captured on video in the area of the grandparents’ home.
Investigators say an Amber Alert remains in place and is continuing to provide police with tips from the public.
