By Steve Hopkins A soured business deal between a suspect in the case of a missing Calgary boy and his grandparents, is now at the centre of a hunt for the trio. Nathan O’Brien, five, and his grandparents Alvin and Kathryn Liknes were reported missing last Monday and were last seen at the Liknes Arkhill home on June 29. On Saturday police took Douglas Garland in for questioning. It was believed the 54-year-old, from Airdire, Alberta, was driving a green Ford F-150 pickup seen near the Liknes family home on the night they disappeared.
