CALGARY - Les enquêteurs retournent à la maison des grands-parents Alvin et Kathy Liknes à Calgary, où leur petit-fils et eux-mêmes ont été vus pour la dernière fois avant leur disparition.
La police a indiqué qu'elle ratisserait la propriété des grands-parents dans le cadre d'une opération à trois volets, samedi, à la recherche de plus d'indices.
Le couple et leur petit-fils de cinq ans, Nathan O'Brien, sont disparus de la maison le 29 juin.
La police avait déjà fait état de preuves d'un incident violent dans la propriété.
Les équipes continuent aussi de ratisser la propriété rurale de la personne d'intérêt Douglas Garland près d'Airdrie, au nord de Calgary, de même que plusieurs hectares de terres à proximité.
La police fait également des recherches dans un site d'enfouissement dans le nord-ouest de Calgary.
