JOHANNESBURG - The duties of a prosecutor, absent witnesses and forensic chain-of-custody disputes have all featured in the closing argument of the Betty Ketani murder trial.

After submitting lengthy written arguments both sides have had a final chance to address the court today in a trial that began more than a year and a half ago.

Three men stand accused of kidnapping and murdering Ketani 16 years ago in a case that revolves around the discovery of a hidden confession under a carpet.

Prosecutor Herman Broodryk argued the role of a prosecutor was to firmly and fairly present the state's case.

He said several witnesses and Ketani's former boss were not called for various reasons.

"For the state to call him would be like we are playing chess against ourselves because we don't know what this witness is going to say."

But defence advocate Laurence Hodes disagreed.

"It's worse than playing chess against yourself, you actually checkmate yourself."

The next step is judgment.
