The correct answer shall be:

• The police arrested Nicole for fraud because they suspected that she had staged the break-in in order to make a false insurance claim for the stolen ring.

• The lack of signs of a break-in, combined with the broken window and messy interior, suggested that the crime scene had been tampered with.

• The dirty footprints on the carpet may have been left by Nicole or someone she hired to make it look like there was an intruder.
• Nicole must have stagged the robbery making it look like someone else had stolen her ring but as there was no such sign of a break-in and the only person who had the key to the house was Nicole herself it would have been clear that she was lying.
