The father of British photographer Julie Ward, murdered in a Kenyan game reserve in 1988, on Thursday said he would present fresh evidence to Kenyan investigators in what could be his last effort to resolve the mysterious death.
John Ward told AFP in Nairobi that he had faith President Mwai Kibaki's government would wrap up the long-drawn investigation and bring suspects to book.
"I have new evidence to present to the government," said Ward, who began a personal investigation when his daughter vanished in Kenya and has campaigned tirelessly to bring her killers to justice.
"With the evidence, there should be a will to resolve this case once and for all. If we can't resolve it this time, probably it will not be resolved ever," he said, hinting that this could be his final attempt.
The charred and mutilated remains of his daughter, from Bury Saint Edmunds, eastern England, were found in the Maasai Mara game reserve in September 1988.
An inquest in Kenya concluded that she had been murdered, and not slain and eaten by wild animals as initially suspected.
But two criminal trials in the east African country in 1992 and 1999 resulted in the acquittals of two Kenyan park wardens and a park worker who had been charged with her murder.
"I believe this government has the will to resolve the murder," Ward added, declining to reveal details of his fresh evidence, part of which was collected by British police.
"Previous investigations were politically stopped by the government," he added, referring to the government of president Daniel arap Moi, who retired in 2002.
Ward said previous evidence had always suggested that Julie had been alone when she drove out of the lodge, in Kenya's sprawling Maasai Mara game reserve.
But three years ago when Ward was in Kenya a new witness had come forward saying they had seen 28-year-old Julie drive away from the lodge with a man dressed in camouflage gear and carrying a rifle, he said.
Ward, who is in his early 70s, said British police officers involved in reinvestigating the case had known about the witness for three years but had not made use of the information.
"British police believe the case can be resolved this time round," he added, speaking to AFP from his hotel room.
In 2004, British coroner Peter Dean ruled at an inquest held in the town of Ipswich that Julie was "unlawfully killed" and explained that "the net is closing around those responsible for this brutal and awful crime".
