This wasn't recently, but in the Chelsea King case, they did exactly what appears to be happening here. Arrested the person they suspected on a charge of not registering as a sex offender to keep him around and, as it turns out, to see if they could get him to confess.I have a question. Is it normal for LE to not name a suspect or POI until DNA results come back? Let's say in a situation like Kelli's case? Can anyone think of any recently?
While he was in jail, unbeknownst to the public, deals were made taking the DP off the table in exchange for confessing AND confessing to another murder and telling where that body was (closure for the other girl's family). In this case, Chelsea's family was asked if they would accept taking the DP off the table, and for the sake of the other girls family, they agreed. BTW, while Chelsea's body was found fairly quickly (lousy hiding job in a well traveled park trail area)the missing girl's body might never have been found (still not a great hiding job, but not in an area a lot of people go). Given several hours, a body can end up anywhere.
So yeah, there are cases where they don't name a POI or suspect until they have all their ducks lined up in a row.
