Senior investigators from American Samoa's Criminal Investigations and Intelligence Bureau have made an unannounced vist to the Tafuna Correctional Facility in connection with the stabbing of a taxi driver in Leone nearly two weeks ago.
Two inmates are considered key suspects in the stabbing and one has confessed.
According to investigators, items which were taken from the taxi driver have been found in one of the inmate's possessions.
However there has been no record of an escape by inmates at the jail during the time of the attack.
The investigators findings have led to questions about whether actual head counts of inmates are carried out.
