When it comes to a missing person case, especially a child any information that can be gathered from a parent can't be beneficial to the detective. Around the 25 minute mark the father is trying desperately to give information to the detective and the detective flat out ignores him, and even seems bothered by the father. The police have a 48-hour hold on the suspect which will expire in a few hours, they say they have no reason to hold him, yet he attempted to run them over with his RV which is attempted assault on a police officer, those are charges that certainly could be used to detain the suspect.
