Former Vancouver mayoral candidate Peter Ladner says he still wants the city to be known as a safe place, despite the killing of his sister on a trail near the University of British Columbia on Friday.

Wendy Ladner-Beaudry, 53, was found dead at about 2:40 p.m.near Pacific Spirit Regional Park, close to SW Marine Drive and Camosun Street.

Police did not release a cause of death, but said Ladner-Beaudry's death was the result of foul play and the attack may have been random.

Speaking to reporters Saturday, Ladner said despite his sister's death, he wants Vancouver to be known as a safe city.

"Our family, all of us, pledge to work diligently with the police, the neighbours and the wider community to bring this killer to justice and establish the safety of our entire community," he said.

"Please, if you know anything, that might help solve this crime, let the police know."

Ladner-Beaudry's husband, Michel Beaudry, said his wife was a dedicated mother to their two daughters.

He said she would be fondly remembered for her work with the BC Games Society, where she was a tireless advocate for women in sports.

"The family and friends of Wendy Ladner-Beaudry are devastated by this random, senseless act of violence that has ended the life of someone who was so loved and cherished," Beaudry said.

Police have not identified a suspect, but RCMP Cpl. Peter Thiessen said more than 60 officers were working on the case, conducting a grid search of the park where Ladner-Beaudry's body was found.

Thiessen also cautioned the public to be vigilant after the attack, saying people using trails in the area should do so with a companion and should avoid wearing headphones, which block out outdoor sounds.

Thiessen advised trail-goers to carry a whistle or battery-powered personal alarm.

Pacific Spirit Regional Park comprises 763 hectares of forest land.
