DNA from blood on suspects’ incinerator and gloves linked to victim Tim Bosma, murder trial told

HAMILTON, ONT. — Bloodstains on The Eliminator — the macabre name of an incinerator where charred human remains were found — and on black rubber gloves police pulled from the pocket of an accused killer have been linked, with astounding statistical probability, to victim .

The results of forensic science reports, presented to the jury at the first-degree murder trial of and Monday, highlighted dramatic testimony linking the two men to the grim end of Bosma, 32, who vanished on a test drive with two strangers who answered his ad for a pick-up truck he was selling online.

A DNA comparison of two blood drops on a metal ledge below the loading door of the incinerator police found on Millard’s farm suggests it was Bosma’s blood, the jury was told.

Similar results were obtained from DNA comparisons of blood found on the outside of a glove, while testing of DNA found inside one of the two gloves was compatible with Millard’s DNA profile and from inside the other with that of Millard’s girlfriend, Christina Noudga, the jury heard.

James Sloots, a forensic biologist with the Ontario Centre of Forensic Sciences, testified Monday on his analysis, interpretation and comparisons of DNA drawn from body fluids found on items collected by police in the Bosma case.

His linking of his testing to the people involved in the case came through a recitation of statistics on the probability of linking DNA to specific people, in this case the victim, the accused killers and their friends.

DNA is not “matched” to a specific person in the same way fingerprints are. Statistically speaking, it is possible a random person could share the same DNA profile with someone else, but the chances are exceedingly slim.

When comparing two good-quality DNA samples, there would be one chance in 18 quadrillion (“18 followed by 15 zeros,” Sloots said) that the DNA sample is from someone else.

As he described it, “it is highly unlikely.”

Sloots was closely involved with the case almost from the beginning, taking the unusual step of doing on-scene sample testing and recovery instead of merely examining samples sent to the centre by police.

“There were many different locations of blood,” the forensice biologist said while being questioned by assistant Crown attorney Craig Fraser, one of three prosecutors in the case.

On May 14, 2013, eight days after Bosma vanished, Sloots tested Millard’s shoes and leaves from underneath The Eliminator where it was found looking for blood.

He found blood on none of those items. But he found it elsewhere, the jury was told.

Police gave Sloots Bosma’s toothbrush from which to draw a sample of the dead man’s DNA to compare with blood samples taken by police.

The jury has heard that after Millard was arrested and handcuffed on May 10, 2013, police found $350 in cash and three black, synthetic rubber gloves in his breast pocket. An examination of the gloves revealed blood stains on the finger tips.

Sloots compared Bosma’s DNA to bloodstains found on his truck, which police discovered in a trailer parked in the driveway of Millard’s mother’s home. The inside and underside of the vehicle was spattered with blood, including the dashboard and cup holders inside, and the axle and muffler outside.

In each case there was a statistical probability it is Bosma’s blood.

As the quality of the sample falls, the chances of it being from someone else increases, but it remains a statistically remote possibility.

Sloots tested cigarette butts, discarded by Smich and retrieved by police surveillance officers who were secretly watching him, to generate his DNA profile for comparison.

He tested a drinking straw discarded by Millard’s girlfriend, Christina Noudga, while she was similarly being watched, to generate her DNA profile. Police obtained a consensual DNA sample from Smich’s girlfriend, Marlena Meneses, to build her profile, court heard.

The jury has already been told Noudga and Meneses are expected to testify for the Crown at the trial.

Millard and Smich have pleaded not guilty.
