Forensic officer in sixth day of testimony at Dennis Oland murder trial

SAINT JOHN, N.B. — A forensic identification officer with the Saint John police department is testifying for a sixth day at the second-degree murder trial of Dennis Oland.

The defence resumed its cross-examination of Sgt. Mark Smith today after he told the jury a day earlier that the scene of Richard Oland's murder was one of the bloodiest he had ever encountered.

Oland is accused of killing his father, whose body was found in a pool of blood in his Saint John office on July 7, 2011.

Defence lawyer Gary Miller has focused questions on the crime scene and the large amount of blood spatter.

Smith has testified that no blood was found in Dennis Oland's car, on a logbook, or any of the shoes seized from the home of the accused.

No murder weapon was ever found.

Smith testified Wednesday that some of the 40 blows to the businessman's head were caused by a hammer-type instrument while others were inflicted with a blade-like weapon.

Smith says the blade-like weapon left wounds that were six to seven centimetres long, while the hammer-like impacts were round and about three centimetres in diameter.
