The tests for determining the voluntariness of a confessional statement have been consistently applied by this Court in a plethora of cases as follows: (1) Whether there is anything outside the confession to show that it is true. (2) Whether the statement is corroborated, no matter how slight (3) Whether the facts contained therein, so far as can be tested, are true. (4) Whether the accused person had the opportunity of committing the offence. (5) Whether the confession of the accused person was possible. (6) Whether the confession was consistent with other facts which have been ascertained and proved in the matter.
