Police Detective Inspector Augustus Nkrumah, the investigator who took over Ya-Na case on Tuesday said his investigations into the matter reveals that the chief died as a result of decapitation.
He said even though he had not contacted the pathologist who conducted autopsy on the body, his contacts with one Inspector Abandze, one of the initial detectives who enquired into the matter confirms it.
He also insisted that though he had not read both the Wuako Commission and the Special Police Investigative Reports his investigations on the matter are true.
Inspector Nkrumah was speaking during cross-examination by Mr Philip Addison, Lead Counsel for the 15 accused persons who are standing trial for their involvement in the murder of the Ya-Na Yakubu Andani II.
He explained that the first time that he went to Yendi was on April 9, when the Police arrested the accused persons.
Inspector Nkrumah said as an investigator on the matter, he took the opportunity to visit the Gbewaa Palace to make his own enquiries to get first hand information on the matter.
He said because of the tension in Yendi, he was provided with police and military escort who took him round various parts of the Gbewaa Palace where he found bullet holes.
He said he also visited the Prison Quarters, the place where about five witnesses claimed they saw the murderers of the Ya-Na as well as the houses which were set ablaze near the palace.
When he was asked by Defence Counsel why some of the people who were arrested initially were not among the accused persons, he said some of them were freed by the Human Right Court.
Inspector Nkrumah refuted claims from the Defence that most of the witnesses he spoke in Yendi and invited to come and testify in the case were Andanis.
He also denied knowledge that Mohammed Achana aka Red who was a warrior of the Ya-Na was trained in Afghanistan and Pakistan.
Meanwhile Police Detective Inspector Charles Adaba, the investigator who undertook enquiries into the Yendi crisis in 2002 had testified at the on-going trial.
Inspector Adaba who tendered to the court a copy of the Police Special Investigative Report, said on March 24, 2002, a Police sergeant was stationed at the Yendi Divisional Criminal Investigation Department.

Inspector Adaba said on April 4, 2002 the police did a report on the people who died in the Yendi crisis and where they were buried before the Wuako Commission was established.

He said out of the 30 people who died only one Iddi who belong to the Abudus died at the Yendi hospital.
