NAIROBI, Kenya (AP) _ A Kenyan judge Thursday postponed the trial of a former game park warden accused of killing a British tourist.

Judge Daniel Aganyanya granted a request by prosecutors for more time to gather evidence in the trial of Simon ole Makallah, now assistant director of the Kenyan Wildlife Service. The judge scheduled opening arguments for Feb. 26.

State Prosecutor Salim Dhanji told the court Thursday the evidence accumulated so far was ``incomplete in a number of technical aspects.'' He did not elaborate.

Makallah has pleaded not guilty to the charges. If convicted, he could face the death penalty.

Julie Ward's mutilated and charred remains were found in September 1988 at the Masai Mara Game Reserve, near Kenya's border with Tanzania. Officials first claimed the 28-year-old Ward had been attacked and killed by wild animals.

It is the second time state prosecutors have brought charges in Ward's death. Two park rangers accused of killing Ward were acquitted in 1992. The judge in that trial criticized police for conducting a flawed investigation.

Both Makallah and another game reserve employee, David ole Nchoko, were prosecution witnesses in the first murder trial. Nchoko also has been charged in Ward's killing.
