The defendant, suspended police officer Steven Numbos of East Sepik Province, returned to the Waigani Committal Court today for a brief mention of his case.
His case was further adjourned to April 4 after police prosecution gave an update to the court on the progress of the case.
The 44-year-old was formally arrested and charged with wilful murder on Dec 30, 2016.
Police allege Numbos shot a man, known to the court as Ija Mulugu, using a high-powered rifle on July 22, 2016.
