A prosecutor says that a GPS attached to David Woods' vehicle led police to the body of his missing wife.

Prosecutor Michael Segu made that contention in his opening remarks to the jury at the first degree murder trial of David Woods.

The four-week trial began Monday at Court of Queen's Bench in Saskatoon.

Woods is accused of killing his wife, Dorothy. She went missing from the couple's east-side home on the Remembrance Day weekend in 2011. Her body was discovered by police in a culvert near Blackstrap Lake, south of Saskatoon, two months later.

David Woods was charged shortly after.

Dorothy Woods, 45, operated a daycare from her home and participated in the city's colourful roller derby league. Posters asking for help in locating her were spread across western Canada in the weeks following her disappearance.

David Woods is being tried by a jury of seven women and five men.

Segu said that the Crown will show that tape and other things found on Dorothy's body were the same bought by her husband. The jury also heard how Dorothy Woods died of ligature strangulation, with blunt force trauma as a contributing factor.

A police witness testified that David Woods showed "little to no anxiety at all" in the days following his wife's disappearance.

The trial continues today.
