Timeline: Missing Calgary family Nathan O'Brien, Alvin and Kathryn Liknes

WATCH: Global's Paul Haysom looks back on the investigation into the disappearance of Nathan O'Brien and his grandparents, Alvin and Kathy Liknes.

Two-and-a-half years since five-year-old Nathan O’Brien and his grandparents Alvin and Kathryn (Kathy) Liknes were last seen, Douglas Garland was found guilty of three counts of first-degree murder in their deaths.

Here’s a timeline of events in the missing persons investigation, from the Amber Alert to Garland’s trial, which began Jan. 16 and ended Feb. 16, 2017.

June 28-29, 2014 – Nathan’s grandparents held an estate sale in the 100 block of 38A Avenue S.W. The Liknes’ had bought a home in Edmonton, where they were planning to live after spending time in Mazatlan, Mexico. The sale was planned to help get rid of some of their belongings ahead of the move.

June 29, 2014 – Nathan’s mother left him at his grandparents’ home for a sleepover following the estate sale. The last time he and his grandparents were seen was at around 10 p.m.

June 30, 2014 – Nathan’s mother called police from his grandparents’ home around 10 a.m. when she went to pick up her son, but found no one at home. Police issued an Amber Alert later that day.

Police said evidence found in the Parkhill home suggested the disappearance may be suspicious, since it was “not in the condition it typically would have been left in,” according to Kevin Brookwell from the Calgary Police Service. Everyone’s vehicles were accounted for.

July 1, 2014 – Police went door to door to speak with neighbours of the grandparents. Neighbours said they saw Nathan playing in the backyard Sunday afternoon, with his grandfather watching nearby.

Police added the trio may have left their home against their will. At that time, it was too early for police to say whether the estate sale was connected to their disappearance.

July 2, 2014  – Nathan’s parents, Rod and Jen O’Brien, tearfully spoke directly to their missing son in a press conference.

“Nathan, your mom and dad, Luke and Maximus, your whole family loves you,” said an emotional Rod O’Brien. “Nathan, you are our superhero right now and we’re going to bring you home very soon.”

Police asked anyone who was at the Liknes’ June 28 to 29 estate sale to speak to police at the Parkhill Community Centre starting July 3.

July 3, 2014 – Police investigators spent 12 hours at the community centre, having asked anyone who purchased an item at the Liknes’ estate sale to bring a photo of that item.

“We just want to make sure we’re aware of what was sold,” explained Calgary Police Staff Sgt. Doug Andrus.

“In other words, if anything was taken after the sale was completed.”

Andrus said police looked at pictures of items sold at the estate sale and asked people to provide fingerprints to eliminate fingerprints found at the crime scene.

July 4, 2014 – Police confirmed a “violent incident” occurred inside the residence.

“Based on the evidence at the scene, somebody would be in medical distress,” said Andrus, adding he expected forensic lab results within several days to a week.

Investigators released two photos of a green truck that was seen “several times” in the area the night of the family’s disappearance and asked the owner to come forward.

July 5, 2014 – Police conducted an area search near the home of Nathan’s grandparents for the second time, to make sure nothing was overlooked in the initial search.

Police questioned Garland, but he was later released in connection to the case.

July 9, 2014 – Police confirmed a green truck was seized from Garland’s property but continued to ask the public to call police if they saw any other trucks matching the description.

Garland appeared in court, facing an additional charge of possession of a stolen credit card. The Crown consented to release Garland on bail on July 11 if he could provide an address where he planned to live.

Police began searching the Spy Hill Landfill in northwest Calgary, looking through the waste as a precaution.

July 10, 2014 – Police searched a second landfill off of 17 Avenue and 68 Street S.E.

quantity of chemicals were located at the Garland home in Airdrie, but police said it was too early to speculate what they were.

Hundreds of people attended a candlelight vigil for the missing boy and his grandparents, just a short distance from the Liknes’ home.

July 11, 2014 – The Crown agreed to the release of Garland from custody Friday afternoon.

An Amber Alert remained in effect for five-year-old O’Brien and his grandparents.

July 14, 2014 – Garland was re-arrested and the Amber Alert was discontinued.

Calgary police said they had taken a man into custody and murder charges would be laid Monday afternoon (two counts of first-degree murder related to the Liknes’ and one count of second-degree murder related to O’Brien).

Police said the bodies of the victims have not been found, but the evidence has convinced investigators it has turned from a missing persons investigation to a homicide investigation.
