The mysterious "Pierre Poutine," who ordered fraudulent robocalls, worked off the same computer that was used by a Conservative Party campaign staffer to set up legitimate election calls, court documents allege.

The documents, obtained by CTV News, were filed in court by Allan Mathews, Elections Canada's investigator in the electoral fraud probe.

The in-depth papers mark the latest chapter in a vote-suppression saga that began more than a year ago during the 2011 election campaign.

According to Mathews, computer logs were provided by RackNine, the Alberta-based firm that supplies dialling services. RackNine is not accused of any wrongdoing.

Mathews states in the court documents that client #93, which was the account used by Pierre Poutine, shared an IP address with client #45, which was the legitimate Conservative account for the Guelph campaign. That means both individuals may have used the same computer.

Previously, documents have shown that the campaign of Guelph-based Conservative candidate Marty Burke legitimately ordered 10 phone campaigns that dialled voters between March 31 and May 2 of 2011.

Meanwhile, the court documents also detail on-the-record interviews with Conservative staffers, who told investigators at Elections Canada that a party campaign worker discussed U.S.-style tactics aimed at disrupting voters.

The pair of Conservative workers told Elections Canada that Guelph staffer Michael Sona spoke about misleading voters ahead of last year's May ballot, the documents show.

Sona resigned from his Conservative job in February when the so-called "robocall" scandal first made headlines. Speaking to CTV News, he denied having anything to do with the misleading robocalls.
