In addition to searching the home of the prominent businessman's only son, Dennis Oland, on July 14, police also searched Dennis Oland's vehicle, a 2009 Volkswagen Golf, and his computer, documents filed with the courts state.

They also searched a logbook entitled "The Island Camp," owned by Richard Oland's brother-in-law, Jack Connell, on Nov. 15, according to court documents.

Richard Oland was found dead on July 7 in his Saint John office. Police confirmed the 69-year-old's death was a homicide and said Oland likely knew his killer, but they have refused to give many more details about the investigation.

Oland's son, Dennis, a financial adviser with Wood Gundy in Saint John, was reportedly questioned extensively by police after his father's death.

Oland's wife of 46 years, Connie Oland, was also reportedly questioned.

William Teed will represent Lisa Oland, Mary Beth Watt and Jack Connell in objecting to the media application and advocating for the release of the information to his clients.

Gary Miller will also argue for access to the information for his client, Dennis Oland.
