The defence in a double-murder trial argued Wednesday there is no evidence linking his client, Kelly Clarke, to the fatal shootings.

Clarke is accused of killing Joel Labossiere and his wife Magdalena inside their St. Vital home in 2008.

On the first day of the trial on Tuesday, the Crown told the jury its key witness, Steven Solomon, will testify he was with Clarke from the start to the finish.

The Crown said Solomon will testify he waited outside the home on Chokecherry Cove and watched as the accused broke into the home, before Solomon heard two shots.

Solomon is also expected to testify that Clarke got rid of evidence by throwing a sawed-off shotgun into the Assiniboine River and tossed clothing he was wearing into the floodway.

During testimony Wednesday, Const. Dave Matthews told the court that a month after the slayings, police located clothing, extra shotgun shells and the gun.

Under cross examination from defence lawyer Greg Brodsky, Matthews said there was no blood visible on anything recovered.

Brodsky also asked the constable why five cigarette butts found at the home on Chokecherry Cove were never sent to the lab for testing. Brodsky suggested the butts could have tied Clarke's friend Solomon to the scene, but the constable could not say why they were not tested.

Matthews did tell the jury that DNA was found on some of the clothing recovered by police. A lab expert is expected to give more insight about that when he is called to testify by the Crown. A pathologist and cousin of the victim are expected to take the stand Thursday.
