Police say they are looking into business dealings as they search for a missing Calgary couple and their grandson.
There are reports that the grandfather, Alvin Liknes, was recently forced to close his small gas-exploration company.
There are also reports he once had a bad business deal with Douglas Garland, whom police say they have questioned as a person of interest in the case.
"We are aware of some business issues regarding the family and so we have officers and investigators that are looking at that to see if there's a connection to this disappearance," Calgary Police spokesman Kevin Brookwell said on Thursday.
"I can't get into specifics as to what those are, who was involved, what they look at or how many people are involved, but yes, we have investigators looking into those allegations."
Five-year-old Nathan O'Brien and his grandparents, Kathryn and Alvin Liknes, have not been seen since June 29 after what police say was a violent incident in the Liknes home. The couple had been having an estate sale and were downsizing before moving to Edmonton and then on to Mexico. Nathan was at his grandparents' for a sleepover.
Officers continued to search property owned by Mr. Garland's parents north of Calgary. Mr. Garland was taken in for questioning last weekend and has since been held on unrelated charges of identity theft.
Police are also scouring city garbage dumps for evidence, but say that is standard procedure.
"Shortly after the disappearance was reported we made contact with the three landfill sites in Calgary and we asked that all refuse from the Calgary and surrounding area that goes to those landfill sites be segregated off," Mr. Brookwell said.
"There have been items that have been taken from the landfill site, but we don't know if there's any relevance to this file or not. You can appreciate that we're talking about all landfill that was collected for a number of days following the disappearance, so there is quite a quantity to go through."
Some online business directories link Alvin Liknes with several oil and gas companies, including Vecto Resource Services, Bluesky Oil and Gas Corp., and AKF Holdings Inc.
Metro Calgary has reported that his latest business venture, a small firm called Winter Petroleum Ltd., was forced to close a few weeks ago after its equipment was seized over $800,000 in owed taxes. The National Post reported Alvin Liknes declared bankruptcy in 1994. His wife, a real-estate-agent-turned-website-design consultant, did the same in 2012.
Other media have quoted an unnamed police source saying Alvin Liknes had a bad business deal several years ago with Mr. Garland, but no details have emerged about it.
Court records show Mr. Garland has a criminal past and mental health problems. In 2000, he was sentenced to 39 months in prison for making amphetamines at his parents' farm.
Police have confirmed his sister is in a relationship with a member of the Liknes family. Mr. Garland could be released as early as Friday, when he is next scheduled to be in court.
