Police announced today that Douglas Garland, 54, has been charged with first-degree murder in the deaths of Alvin and Kathryn Liknes, and second-degree murder in the death of five-year-old Nathan O'Brien. Events in the case have included:
June 30: Calgary police issue an Amber Alert after five-year-old Nathan O'Brien and his grandparents, Alvin and Kathryn Liknes, are reported missing. Police say Nathan's mother had dropped her son off at the Liknes home the night before for a sleepover. She found all three family members missing when she went to collect him the next day. Police describe all three disappearances as "suspicious."
July 1: Police express interest in speaking to anyone who attended an estate sale at the Liknes home in the weekend leading up to the disappearances.
July 2: Nathan's parents, Rod and Jennifer O'Brien, issue a nationally televised plea for their son's safe return.
July 3: Police say footage from nearby closed-circuit televisions as well as tips from the public have moved the investigation along, but decline to provide details.
July 4: Police confirm that a violent incident took place at the Liknes home, adding they recovered forensic evidence. They also release images of a green Ford pickup truck and say they believed the unidentified driver may have some information.
July 5: Calgary police and RCMP descend on a property near Airdrie, Alta., just north of Calgary. Police recover the green Ford and take in Douglas Garland for questioning.

July 7: Douglas Garland, 54, appears in a Calgary court on an identity theft charge unrelated to the Liknes/O'Brien disappearance. He is held in police custody pending a bail review. Rod O'Brien tells reporters at the courthouse that there is a connection between Garland and the family, but would not elaborate.
July 8: Calgary police say they have other leads to explore besides Garland and the Airdrie property, but offer no details.

July 10: Police say they are probing business dealings in the Liknes family as part of their investigation. Officers did not provide details, but reports surfaced that Alvin Liknes recently had to close his gas exploration company after equipment was seized for unpaid taxes.
