A Kelowna man convicted of killing a college student in 1993 is awaiting a B.C. Court of Appeal decision on a new trial.

In 2011, Neil Snelson was found guilty of manslaughter in the death of Jennifer Cusworth and sentenced to 15 years in prison.

But last week Snelson's lawyers appealed the verdict.

Friends of the victim are disturbed Snelson is asking for a new trial.

“It's disappointing,” said Jennifer Watson, who runs a Facebook page dedicated to Cusworth.

“We've been going through this for 20 years, and we thought it was to an end. And for him to appeal is just dragging us through it again."

Cusworth’s body was found dumped in a ditch near Kelowna. It took 15 years and improvements in DNA technology for investigators to find a suspect.

But Snelson’s lawyer argues the trial judge should not have allowed the jury to view a video of Snelson talking with RCMP investigators.

"It's almost insulting that he's even applying for an appeal. He got a slap on the wrist for killing our friend. He was charged with first-degree murder and got away with manslaughter,” Watson said.

"It's just discouraging. I want him to own up to what he's done and take accountability for it."

The B.C. Court of Appeal has reserved its decision until later this year.
