Testimony continued Tuesday at a first degree murder trial at Court of Queen's Bench in Saskatoon.

George Allgood, 49, is charged with first-degree murder in the death of his ex-girlfriend, 40-year-old Susan Reinhardt, in 2006.

Sgt. Dean Liebrecht  was there the night Reinhardt was killed. Sgt. Liebrecht  testified that police used a tracker dog, which led them to 4th Avenue N. and 24th Street.

"The police service's dog, in my perspective, is 100 per cent accurate," Sgt. Liebrecht said. "The reason I say that is because the dog is trained to follow the freshest human scent he starts with."

Const. Anthony Nadon also took the stand this morning. He responded to the distress call at a home on 4th Avenue N. in Saskatoon. He said he found Susan Reinhardt shot to death in bed.

Const. Nadon testified that he remembered seeing a black man carrying a dark bag and running southeast at the intersection of 25th Street and 5th Avenue.

On July 15, 2006, police were called to a home on the 800 block of 4th Avenue N., where officers found Reinhardt and 43-year-old David Ristow suffering from bullet wounds. Reinhardt died in hospital, but Ristow survived.

Allgood is also facing a charge of attempted murder.

The court also heard from Michael Pelantger, a former friend of Allgood, who was with the suspect the day Reinhardt was killed.

Pelantger said he knew Allgood as Trevor Hogg and that they hung out often. Pelantger testified that he and Allgood were drinking heavily the day of the murder. He said Allgood left at about 6 or 6:30 p.m. CST.

The trial is expected to last about two weeks.
