The condemned soldier, according to the court-martial, failed to provide a convincing defence in his testimony.
A Nigeria Army General Court Martial on Tuesday sentenced a soldier, Azunna Mmaduabuchi, to death by firing squad for killing an officer.
Mr Maduabuchi had in July 2020 reportedly opened fire on one Lieutenant Babankaka Ngorgi which killed him instantly.
The trial that led to the conviction of the condemned did not reveal if the soldier had any personal grudges with the officer he killed.
Mr Maduabuchi, a private soldier, pleaded guilty but argued that his action was accidental.
But PREMIUM TIMES was informed by inside military sources that the condemned soldier had once gone on AWOL which led to the stoppage of his salary for about six months.
The source said the soldier, who was serving at the 202-battalion in Bama, pleaded with the late Lieutenant Ngorgi, who was his Adjutant, to allow him travel to the state capital to sort out his salary issues, but his requests were repeatedly denied.
It was not certain if it was the issue that pitched the condemned soldier against the deceased officer.
Eight prosecution witnesses told the court-martial headed by Arikpo Ekubi, as president of the court, that they saw the condemned soldier at the scene of the crime still holding the AK47 rifle while the late Adjutant lay in a pool of his blood.
One of the PWs said he saw the private soldier match past him, without complimenting him as his senior as he walked up to the deceased adjutant who was at that time making a call and summarily opened fire on him.
“After opening a rapid action fire on him, the soldier turned to face me and then raised his hands to say ” I have killed him”, the PW said.
