As he did last year, Jeff Buziak travelled to Victoria from his home in Calgary to lead the annual Lindsay Buziak Walk for Justice on the anniversary of her death.
"I made that vow that I would not let this go," he told CBC News.
On Sunday, he again led her loved ones and other supporters in a walk that began at her grave site, proceeded to the home where she was killed, and ended at Saanich Municipal Hall, where the police department has an office.
"The case is unsolved," Buziak said. "It's been six years, and we'd like to see some action there."
Lindsay Buziak was just 24 years old when she died while showing a $1-million home in Saanich on Feb. 2, 2008.
Police said she was lured by an unknown couple to the home, and then stabbed 54 times in an upstairs bedroom.
Saanich Police have yet to make any arrests — a situation that continues to frustrate Jeff Buziak.
"Sometimes I believe they know what's going on and that they're close and you know, 'we're ready for arrests,' and then other times I'm just totally bewildered as to what they're doing, what they know," he said.
Although the young realtor had no known connections to the drug trade or the criminal underworld, investigators have said they believe organized crime could somehow be connected to her death.
