Fraudster Melissa Caddick may have had a "fat wad of cash stashed under the bed" and been hiding out in a low-budget hotel, her husband told police soon after she disappeared.

Detective Sergeant Michael Kyneur returned to the NSW Coroners Court in Lidcombe on Wednesday for his second day of evidence after taking charge of the investigation into the missing conwoman.
