The family of Wendy Ladner-Beaudry says the pain of her death has not subsided in the years since she was found mysteriously murdered.

It was four years ago today that Ladner-Beaudry, the sister of former Vancouver city councillor Peter Ladner, was brutally killed while running in a trail near Vancouver’s Pacific Spirit Park, close to the University of British Columbia.

Peter Ladner and Nancy Edmonds, her oldest sister, both wore shirts bearing her image as they addressed media at a press conference Wednesday, not far from the spot where her body was found.

Edmonds spoke on behalf of Ladner-Beaudry’s husband and children, whom she said did not attend because it was too painful for them.

Peter Ladner read a statement from the family, choking up as he described his beloved sister.

“There’s a murderer loose somewhere, very possibly in this neighbourhood,” Peter Ladner said.

“Those of us close to Wendy lost a trusted sister, a loving mother, a strong wife, a cheerful aunt, a dear friend, a dedicated mentor and a smiling neighbour.”

Sgt. Jennifer Pound of the Integrated Homicide Investigation Team said there is still no motive in the mother’s death, but insists the case has not gone cold.

Pound said while in 95 per cent of homicide cases investigators know who the culprit is, police still don’t know if the crime is random.

"Someone out there knows what happened to Wendy. Four years is a long time to sit on information that could potentially offer hope to a grieving family," she said. 

In April 2011, her family offered up a $30,000 reward for new information that would lead to the capture and prosecution of her killer.

At that time, police said there were still roughly 200 persons of interest in the case, and said the investigation was very active.

Anyone with information is asked to call the Integrated Homicide Investigation Team tip line at 1-877-551-4448.
