Mounties in Kelowna, B.C., have made an arrest in the 16-year-old unsolved murder of a local teen.

The body of 19-year-old Jennifer Cusworth was found dumped in a ditch in 1993. She had been at a party the night of her death.

Const. Steve Holmes of the Kelowna RCMP confirms a person has been taken into custody in connection with her murder, but no other details are being provided.

At a press conference Oct. 15, the lead investigator in the case said new DNA science had given them a possible break. Investigators have gathered over 230 DNA samples since her death. Ten people refused to give a sample.

"We can say from where the items were located around the crime scene that we are confident that it is that of the killer's," Cpl. Bill Parmar said.

The cause of Cusworth's death has never been released.

Investigators have been re-interviewing people who attended the party, as well as their associates.

Jean Cusworth, Jennifer's mother, attended the press conference, and said she was encouraged by the news.

"Hopeful, extremely hopeful," she said. "We've always believed this case will be solved."

Cusworth and her husband Terry return to the spot where their daughter's body was found every year. They say they will keep visiting even if the case is solved.

"It's with us now for the rest of our life," Terry Cusworth said.

"I'll be coming down here with a wheelchair with my carnations. It will still be done even after the killer is caught."

RCMP will release more information at a press conference Monday. Jennifer's parents will be there.
