The Nadia Gehl murder trial has resumed at the courthouse in Hamilton after a week off.

Gehl's husband Ron Cyr, Nashat Qahwash and Zdenek ‘Dennis' Zvolensky are each accused of first degree murder in the February 2009 killing.

On Monday the Crown finished questioning Qahwash, who told the court he had nothing to do with Gehl's murder

The trial had left off with Qahwash being cross-examined. In earlier testimony he said Zvolensky told him he had shot Gehl after Cyr asked him to.

But Zvolensky's attorney accused Qahwash of pulling the trigger and Cyr's lawyer suggested the two men were pointing the finger at each other to save themselves.

After calling a surveillance officer to testify, Qahwash's lawyer rested his case.

On Tuesday the defence lawyer for Zvolensky is expected to begin presenting his case.

There is no word yet on whether Zvolensky or Cyr will testify.
