Chief Inspector Maria Jones failed to comply with instructions to surrender some weapons for ballistic tests in the Hanuabada double killing investigations.
NCD Central police commander Sylvester Kalaut says that the weapons were determined to be the ones identified by investigators.
Kalaut would not say just how many weapons were to be brought in but says instructions were issued and Jones was tasked to surrender the weapons which she failed to do.
He says Jones was identified as one of the officers on the scene at the time of the shooting.
Jones has also been implicated in the Tatana shooting.
