The third day of the trial of the two men accused of murder in the death of Tim Bosma of Hamilton features testimony from one of the lead officers in charge of the investigation.

Det.-Sgt. Greg Jackson from Hamilton police was the case manager on the original investigation. Bosma disappeared on May 6, 2013. 

Jackson's testimony followed fingerprinting expert Det. Rob Felske from Halton police.

Felske said Tuesday in Hamilton court that a thumbprint found on the rearview mirror of Bosma's truck matches the thumbprint of Dellen Millard, one of the accused.

"My conclusion was that the impression found on the rearview mirror was made by Dellen Millard's right thumb," said Felske.

Millard, 30, of Toronto, and Mark Smich, 28, of Oakville, Ont., are charged with first-degree murder.

Earlier Tuesday, court heard testimony from Wayne De Boer, Bosma's downstairs tenant.

De Boer described Bosma's character, saying he was a "very generous person in all areas of his life."

Court also heard testimony from Jesse Kancer, a friend of Bosma's who was at the Bosma home earlier on the day he disappeared.
