OLIVE BRANCH, MS- (WMC-TV) - A man who admitted to Andy Wise that he was part of a scam is back in business, and our chief consumer investigator is back on the job.

The more things change, the more they stay the same.

"You've definitely got mold in your system," Greg Brooks told our undercover producer back in November when she answered a newspaper ad for a $99.95 air duct cleaning.

Little did he know that we already had an HVAC contractor and a certified mold inspector confirm there was no mold in the house.

Now, Brooks is running his own business and he is using the same techniques without credentials. Andy Wise confronted him about his business practices for a second time, this time, with the city's mayor. They wanted to see if Brooks and his new crew have learned from his mistakes.

It's an undercover investigation you will not want to miss Friday on Action News 5 at 10 p.m.

JACKSON, MS- (WMC-TV) - In the fourth day of his own spending trial, Southaven Mayor Greg Davis took the stand in his own defense. His testimony focused on exactly what he bought, when he bought it, and whose money he was spending.

Davis walked up to the witness stand in civil trial Thursday to testify about, what the state auditor's office said is, unsubstantiated spending of city dollars.

The state is trying to recover $70,000 the auditor believes he owes.

Davis acknowledged he did not provide many receipts with his invoices, which is something he never denied. He said credit cards statements create documentation within itself.

Davis did return to businesses like the Mesquite Chop House months later to get receipts when the Mississippi State auditor started looking at his spending. He said he did a lot of business for the city there.

JACKSON, MS- (WMC-TV) - An investigator for the Mississippi state auditor's office testified Monday during Southaven Mayor Greg Davis' questionable spending trial. She testified Davis made claims that were not true.

The Mississippi state auditor is trying to collect more than $70,000 in public money allegedly spent on personal matters.

The state of Mississippi arrived with reinforcements Monday. There were four attorneys from the attorney general's office and one from the state auditors office.

"I said, 'We have a receipt for $1,400.09.' You said that you entertained reps, and it's a clothing store. He said, 'I bought clothes for the reps,'" said investigator Karen Swain in regards to a trip Davis took to the Key West.

Davis and his family went to clothing stores with names like Flirt, French Kiss, and Jungle Paradise.
