What's with the Money flow?

If it was in the cooler and at the Detective's house, how come it was in the Coffee Bean sack? It was only when the Detective suspect's his wife which is much later that it is shown where she hid it in her Washing Machine. But prior to that there is the money shown at the Restaurant basement when the Coffee Bean Sack is opened.

The twists in the story needs to settle down soon. The main attraction in the Drama are the Three Main Leads...
