Hope, Danny, Andy and Win were interrogated alone, without presence of their parents or legal guardians or lawyers. As they are minors police must wait for the arrival of their legal guardians even if the suspects didn't ask for them, or to provide some sort of public legal guardian to bear witness that the interrogation was not under coercion. Otherwise, all the confessions and all the information received during interrogation are inadmissible in the court. And police can not pursuit any leads from such information because it's called "fruits of a poisonous tree" and also inadmissible.
