A forensic anthropologist who helped determine that bones found inside a livestock incinerator on Dellen Millard's farm were from a human being is testifying today at the murder trial of two men accused of killing Tim Bosma of Ancaster, Ont.

Dr. Tracy Rogers, who works at the University of Toronto, told the court the larger bone discovered was from a human arm and that it showed signs of being burned at a high temperature.

Millard, 30, of Toronto, and Mark Smich, 28, of Oakville, have both pleaded not guilty to first-degree murder in the slaying of Bosma, 32.

Their trial is now in its third week in Ontario Superior Court in Hamilton.

On Wednesday, Sgt. Annette Huys described finding bones in the 3.5-metre-high incinerator, marketed as The Eliminator, on the Millard farm. 

Bosma disappeared on May 6, 2013, after taking two men on a test drive of a truck he was trying to sell. His burned remains were found just over a week later.
