The murder trial of Dellen Millard and Mark Smich continued Wednesday with the final day of cross-examination of Christina Noudga.

Noudga was dating Millard in May 2013, when he was arrested for first-degree murder in connection with the death of Tim Bosma.

He has pleaded not guilty to that charge, as has Smich.

The Crown contends that the two men killed Bosma after taking him on a test drive of a truck he was selling, then burned his remains in an incinerator.

The truck was later found inside a trailer parked outside Millard’s mother’s house in Kleinburg.

Jurors have heard that Millard’s mother and Noudga did not know what was inside the trailer, but began to suspect that it may have been the truck – prompting them to wipe clean the parts of the trailer they had touched.

Under questioning from Smich’s lawyer, Thomas Dungey, Noudga said it did not occur to her at first that they were also removing Millard’s fingerprints.

“I (later) realized unintentionally I wiped Dell’s prints off the locks,” she said.

“At the time, I thought he was innocent.”

Wednesday’s cross-examination also touched on the dozens of letters Millard sent Noudga while in prison, even though the two were under a court order not to communicate with each other.

Although some of the letters instructed Noudga to speak to potential witnesses and suggested certain potential defence scenarios, Noudga said that she didn’t act on any such instructions.

She also didn’t turn the letters over to police – saying that she thought by leaving the matter alone, “it was as though nothing had happened.”

A draft of a letter written in response by Noudga was read aloud to jurors.

In the draft, Noudga said she hadn’t figured out how to get in touch with certain people and wanted “some information” on how to do so.

“I’m sure I can be a powerful weapon,” she said.

Noudga testified that she never ended up sending the letter to Millard.

The trial continues next Monday.
