Update: Fox 4 News Interview: http://www.fox4kc.com/news/wdaf-retir...

Time is never on the side of investigators when an infant is missing.

While statistics and history give us reason to be hopeful that Baby Lisa will be found unharmed, the recent developments that have been reported are not promising.

The first news update today was that Baby Lisa’s parents have stopped cooperating with the police. That has been disputed. Dad Jeremy Irwin said that he just needed a break. That is possible. A police interrogation can get intense and aggressive, especially if the police do not have promising leads. Mom Deborah Bradley apparently has failed a polygraph and complained that she was being treated as a suspect. And that may be true.

Parents are, by default, suspects in a child’s disappearance. If a polygraph is failed or some part of a parent’s story does not add up, then police suspicion will be heightened. Of course, if the parents are not involved, their frustration at the accusation will also elevate the tension.

If a parent decides to harm a young child, the case could be very hard to prove. Obviously, the parent’s unfettered control of the child gives them the ability to act undetected. That is a painful truth, but it is reality and we have seen such tragedy before.

The police are doing everything they should be doing. They must be aggressive and pursue any leads or suspicions they have. They have one goal – to find the child.

If Baby Lisa’s parents have nothing to hide, they need to re-establish a cooperative relationship with the police. Maybe an intermediary is needed. Even if both sides have the same goal, their approaches are so different, that the gap needs to be bridged.

If there is something to hide, then some deep soul searching is needed.
