HAMILTON - An accused murderer says he didn't kill Tim Bosma three years ago during a test drive of a truck the Hamilton man was trying to sell.

Mark Smich took the stand yesterday in his own defence and blamed his co-accused -- Dellen Millard -- for Bosma's death.

Smich told the jury Millard fatally shot Bosma and later disposed of his body in an animal incinerator dubbed "The Eliminator."

Smich told the court he and Millard planned to steal a truck and would take vehicles on test drives with the intent of stealing it later if conditions were right.

He says Millard and Bosma were in Bosma's truck on the night of May 6th, 2013, and he was following in Millard's vehicle.

He says when they pulled over, Bosma was slumped over the dash and there was a bullet hole in the window.

Smich, of Oakville, Ontario, and Millard, of Toronto, have pleaded not guilty to first-degree murder in Bosma's death.

Smich is to continue his testimony today, while Millard's lawyer has said he will not call evidence.
