TEMPE, AZ — Dozens of Valley residents are seeing letters in their mailboxes warning them their mail may have been stolen.
The United States Postal Service confirms an unknown amount of mail has been taken from four Valley post office locations.
The first theft happened at the Sun City Main Post Office on November 3. Two more incidents happened November 21 at the Mesa Dobson Post Office and Scottsdale Hopi Post Office. The most recent incident occurred at the Tempe Apache Post Office near McClintock Drive and Apache Boulevard.
"Obviously it's not a good thing," said Jaime Mazzeo. She received a letter at her home that's just a few miles from the location that was hit. "It's going to cause chaos for people who don't realize their bills haven't been paid, or that Christmas gifts that were supposed to arrive haven't arrived."
Mazzeo says she contacted the US Postal Inspection Service Office who's currently investigating the incidents and was told a mail tray was taken from her local post office.
"I feel like there would be security protocols that would prevent that," added Mazzeo.
USPS Spokesperson Liz Davis tells ABC15 they have not connected any of the four thefts, but are sending notices out to residents to keep an eye out for their mail or contact their office if they don't receive it.
The department is also offering a $10,000 reward for information that helps lead to the arrest of a suspect or suspects responsible for the thefts.
"I do think around this time of year people get desperate and they know they can, you know, the chances they're gonna score some higher value items are a little bit higher," said Mazzeo.
