Police say they are looking into business dealings as they search for a missing Calgary couple and their grandson.
Alvin and Kathryn Liknes (LICK'-ness) and five-year-old Nathan O'Brien haven't been seen since June 29.
There are media reports that Alvin Liknes was recently forced to close his small gas exploration company and had declared bankruptcy in the 1990s.
There are also reports that say he once had a bad business deal with Douglas Garland, who police say they have questioned as a person of interest in the missing persons case.
Police spokesman Kevin Brookwell says investigators are looking into business issues involving the family, but refused to elaborate.
Officers continue to search property owned by Garland's parents north of Calgary, as well as two city garbage dumps.
