Police investigating the case headed to a rural home near Airdrie on Saturday, scouring the area during a meticulous grid search.

On Monday, about 25 police vehicles parked at the scene, as dozens of officers again launched a thorough search of the area.

54-year-old Douglas Garland, who lives on the acreage, was taken into custody for questioning.

His parents own the land, and it’s believed that Garland has links to the Liknes family. Police have called him a person of interest.

Garland is no stranger to police; he served 39-months in a Federal prison in 2000 after being convicted of drug trafficking.

WATCH: Douglas Garland was taken into custody and appeared in court Monday morning on another matter. Nancy Hixt reports from the Calgary Courts Centre.

He appeared in court via CCTV on Monday for an unrelated charge of identity theft.

During his brief appearance, Garland told court he wished to speak to duty counsel. The matter has been put over until at least Wednesday.

Nathan O’Brien’s father Rod was in court for Garland’s appearance, but declined to comment.

In the meantime, green ribbons line the Parkhill street where the Liknes’ home is. The Parkhill/Stanley Park Community Association handed them out over the weekend, as a symbol of hope and show of support.
