Last Thursday, I wrote about a no-tech scam that involved crooks putting a sticky substance in mailboxes so that letters deposited by people wouldn’t fall to the bottom.

The crooks would then steal the envelopes people thought were deposited. They’d get checks, personal information and a lot more.

Postal officials never called me for comment until — as often happens — after they were (probably) embarrassed.

So here’s an update. The Postal Service says that seven people were arrested for stealing the mail of the person whom I referred to in that column as Marilyn.

“Customers who notice any sticky residue or damage to the blue mailbox should take their mail to the local post office and report it. This creates a record of possible criminal activity in the area,” the USPS told me to tell you.
