After weeks of testimony from Crown witnesses, defence lawyers needed just two hours to present their case at the murder trial of David Thomas.

Thomas is accused of killing Denise Bourdeau following a New Year’s party held to ring in 2007.

He has pleaded not guity.

Multiple witnesses testified that the pair arrived separately at the party, which took place at a Waterloo restaurant, but left together.

Bourdeau’s body was found several months after her disappearance, along the banks of the Grand River.

Monday, court heard from private investigator Chad Owens.

Last winter, Owens took photographs of various bridges over the river.

He testified that the bridges were all accessible, and in almost all cases were not fenced in.

Also testifying for the defence was Thomas’ step-sister, who said she had met Bourdeau twice.

The second time, she told the court, was at a family Christmas gathering days before Bourdeau’s disappearance – during which she seemed a little nervous, but generally happy.

Thomas did not testify in his own defence.

The case is expected to go to the jury sometime next week.
