The military's court martial sitting in Maiduguri, Borno State sentenced Maduabuchi to death by firing squad during a ruling on Tuesday, January 12, 2021.

The private was found guilty and convicted in accordance with Section 106 of the Armed Forces Act.

Maduabuchi shot and killed Lieutenant Babakaka Ngorgi on July 29, 2020, just months after the victim got married. 

The trooper, while serving in 202 Battalion of 21 Special Armoured Brigade in Bama, Borno State allegedly 'went beserk' and fired at the officer in front of the Unit's Headquarters reportedly for denying him a welfare pass.

"The gravity of the crime that you have committed against the innocent officer which by application is a crime against humanity and an attempt to drag the good name of Nigerian Army into mud must be sanctioned appropriately.

"The general court martial for the offence of murder as provided by section 106 of the Armed Forces Act is death. This sentence is to be carried out by firing squad," the President of the Court, Brigadier General Arikpo Ekubi, said.

The Army said at the time of the incident that Maduabuchi was suffering from depression.
