Crown prosecutors are still seeking a motive in the extortion case against Mayor Rob Ford’s friend Alexander “Sandro” Lisi, a Toronto court heard Friday.

“We do not know precisely what motivated Mr. Lisi,” crown attorney John Patton told Mr. Justice Ian Nordheimer during arguments over how much more of two search warrant documents can be released.

Nordheimer approved the release of a few more sections at noon Friday, but has reserved his decision on the bulk of the information.

In the new documents released, detectives state that they intercepted calls between Ford and Lisi during the two-day time period when the alleged threats by Lisi were made to the people believed to have the video. Police only know the calls were made, not what was said on them.

Lisi is facing drug trafficking and extortion charges, the latter related to his alleged attempt to retrieve the crack cocaine video of Ford from the man who made it and an associate. Lisi’s lawyer argued that releasing details of the alleged threats, and wiretap information connected to the allegations, would severely prejudice his client’s right to a fair trial. Media lawyers argued that the public has the right to know the details of the case because it involves a high-profile investigation of the top municipal politician in Canada’s largest city.

In the portions that were released, investigators have noted they discovered telephone contact between Ford and Lisi during the May 16-18 2013 time period when Lisi allegedly threatened the two men to turn over the crack video.

Investigators say that during the key two-day time period (news of the video’s existence surfaced on May 17) they have learned from phone records that Lisi was in contact with Ford, both through his cell phone, ONSTAR and home number, and Lisi was also in contact with Elena Basso, the woman at whose house the video was filmed in February 17, 2013. Lisi was also in contact with Mohamed Siad, who made the video, his associate Liban Syad, and with the mayor’s assistant Thomas Beyer.

Also in the document released were reports of a death threat of sorts directed at Mohamed Farah, the man who tried to broker the sale of the video to the Star and Gawker.

In one wiretap (only some phones connected to the case were wiretapped), detectives overheard an unknown person discussing on May 18 how news of the video is everywhere. Blame for this seems to be directed at Farah and detectives say the unknown man on the phone says to another man “if he could kill anyone it would be (Farah),” according to the search warrant document filed in court. Farah, a community worker who had told the Star he was trying to help people involved in drugs start a new life, is referred to by his associates as “Big Dog.”
