Federal investigators say a "serial mail thief" who treated North Side condo mailrooms like her own supply closet is headed to state prison. A Chicago woman has been sentenced to six years in the Illinois Department of Corrections after pleading guilty to burglary charges tied to mail thefts in condominium and apartment buildings across Chicago's North Side and into northern Cook County. Authorities say the stolen mail fed identity theft schemes and check fraud that hit local residents in the wallet.
According to NBC Chicago, the U.S. Postal Inspection Service identified the defendant as Veronica Cavallari. She pleaded guilty to two counts of felony burglary earlier this month and received a six-year term. NBC reported that a joint investigation tied those burglaries to car thefts and other alleged crimes across the North Side and northern Cook County.
Investigation and arrest
A press release from the U.S. Postal Inspection Service says inspectors and Chicago police arrested Cavallari after a vehicle pursuit on Dec. 15, 2025, then connected her to multiple burglaries and mail thefts in building mail rooms. Investigators say the stolen mail was used to drive identity theft and check fraud, turning routine bill-paying into a risky proposition for victims. The agency also noted that Cook County prosecutors filed firearms and related misdemeanor charges while burglary and automobile theft counts were still pending at the time of her arrest.
How mail rings operate
Investigators and local reporters have repeatedly warned that criminal crews often rely on stolen or duplicated USPS "arrow" master keys to get into secured mail rooms, giving them access to checks and personal information in bulk. CWBChicago earlier documented that pattern in the investigation and reported that a single key can unlock mailboxes across a wide area, quickly generating material that can be converted into fraud.
What victims should do
The Postal Inspection Service urges anyone who believes their mail may have been stolen to call 1-877-876-2455 or file a report online, according to the U.S. Postal Inspection Service. Residents are also advised to keep a close eye on bank and credit card statements and to consider placing fraud alerts if they notice suspicious activity.
Legal notes
Cavallari pleaded guilty to two counts of felony burglary and was ordered to serve her sentence in the Illinois Department of Corrections, NBC Chicago reported. Authorities say the case stemmed from a multi-agency probe and that additional charges were still pending at the time of her arrest.
