Sixteen year old Tamika Griffith of Princes Town was found with a bullet wound to her head on Tuesday afternoon.
At the time, her male relative, also 16, told investigators that he had left her alone at his Sookoo Trace, Claxton Bay home to go the parlor and when he returned, found her with the gunshot wound to the head.
However, the Form Four boy has now confessed that the shooting of his relative was accidental.
The boy told police that he was being paid $150 per week to keep the weapon for another relative.
While Griffith was there on Tuesday, the boy said he showed the weapon to her, and it was while taking it out of her hands that it discharged, with the bullet hitting her in the head. He then called the owner of the gun who collected it, before notifying the police.
Griffith, a Form Four student of Princes Town East Secondary, was still alive when the police arrived but died while undergoing surgery at the San Fernando General Hospital.
The relative who owns the gun, has since been held and is now in custody at the Oropouche Police Station pending further investigations.
Griffith had been at the relatives house doing online studies.
