OTTAWA The digital trail left by the suspect behind misleading robocalls to voters in Guelph, Ont., on election day 2011 has sharply narrowed, with Internet records linking the mysterious "Pierre Poutine" to an account held by a worker from the campaign of local Conservative candidate Marty Burke.

Newly released court documents also show that a Conservative Party staffer told Elections Canada that he been asked by another Burke campaign worker in the days before the vote about making disinformation calls.

The documents strongly suggest links between the Guelph campaign and the phoney calls, which Conservatives seized on to cast the robocalls scandal as the work of rogue elements working at the riding level, not a co-ordinated campaign.

The sworn statement filed by Elections Canada investigator Al Mathews and released Friday makes a crucial link between the calls and the Internet Protocol address (IP) used to arrange the fraudulent calls made through Edmonton voice-broadcasting company RackNine.

The IP address was used both by Burke campaign worker Andrew Prescott to arrange legitimate calls with the company and by whoever placed the fraudulent calls that sent hundreds of electors to the wrong polling stations, Mathews alleges.
