I ' m just going to copy paste my last reply . Honestly , if I were innocent of any wrong doing I would never consider that as worth mentioning and this is only if I even remembered it . I ' m sure I would look very suspect if I suddenly just volunteered something so off topic when being questioned about a missing girl . I know I would certainly find it suspect if somebody told me something like that . And they would definitely both be high on my suspect list if they both said the same thing for no apparent reason . It has collusion written all over it . But in the end , the reality is that once a person becomes a suspect everything they do or don ' t do , say or don ' t say can be interpreted as an indication of guilt , which is why we must always be self aware if our own confirmation biases . We must be able to distinguish between what the evidence tells us and what we want to believe . Failing to mention something that Barb remembers four months after the incident with no corroborating evidence is not proof that Brendan had any knowledge of the crime by any standard .
