Quick Answer: Five members of a Miami check fraud ring pleaded guilty to stealing $1.7 million through mail theft and check washing. They used stolen U.S. Postal Service keys to access mailboxes, altered stolen checks, and cashed them using counterfeit IDs. The case highlights a national surge in mail theft-related check fraud — the FBI reports suspicious activity reports nearly doubled between 2021 and 2023.
This case struck home for me because on my true crime podcast I do I did a recent episode on one such case. You can listen to The SWIPE GOD Rapper Who Convicted Himself: Check Fraud Case.
A criminal ring that stole $1.7 million in checks from U.S. mailboxes has pleaded guilty in federal court in Miami — and their methods reveal how vulnerable your outgoing mail really is.
The Department of Justice announced on February 12, 2026 that five defendants from Miami Gardens, Florida — Angel Joe Gonzalez (28), Evens Necler Monestime (27), David Gonzalez (23), Cristina Azahares (27), and Adriana Ginel (56) — pleaded guilty to charges including bank fraud, conspiracy, aggravated identity theft, and drug trafficking.
How the Scheme Worked
The operation ran from September 2021 through May 2023. According to the DOJ, the ring used stolen USPS arrow keys — master keys that open collection boxes and cluster mailboxes — to access mail across the Miami area.

What’s an Arrow Key? USPS arrow keys are master keys that open virtually every blue collection box, apartment cluster box, and neighborhood delivery unit in a given area. When criminals steal one, they gain access to thousands of mailboxes — and every check inside them.
Once they had the mail, the defendants:
- Stole personal checks from mailboxes
- Chemically “washed” the checks to erase the original payee and amount
- Rewrote the checks for larger amounts payable to themselves
- Created counterfeit identification documents to cash them at banks
- Sold stolen checks through a Telegram group with approximately 2,000 members
When officers executed search warrants, they discovered six stolen postal keys, 40 counterfeit cards, 27 cell phones, firearms, and drugs including heroin, cocaine, MDMA, and fentanyl.
What the Defendants Face
Angel Joe Gonzalez and Evens Necler Monestime face sentences ranging from 5 years to life in prison due to the drug trafficking and firearms charges stacked on top of the fraud. David Gonzalez, Cristina Azahares, and Adriana Ginel face between 2 and 30 years for bank fraud and aggravated identity theft.
This Isn’t an Isolated Case — It’s a National Crisis
This Miami ring is part of a much larger problem. Mail theft-related check fraud is surging across the country, and the numbers are alarming.
The FBI issued a public alert in January 2025 warning that suspicious activity reports related to check fraud nearly doubled between 2021 and 2023. Financial institutions filed more than 682,000 suspicious activity reports related to check fraud in 2024 alone — a 139% increase compared to 2020.
According to FinCEN’s analysis, once criminals steal checks from the mail:
- 44% are altered (washed) and deposited
- 26% are used as templates to create counterfeit checks
- 20% are fraudulently signed and deposited without alteration
The USPS Office of Inspector General reported over 52,000 high-volume mail theft attacks in FY2024 — up 156% since FY2019. Arrow key thefts specifically surged 150% between 2020 and 2024, rising from 1,374 incidents to 3,437.
Key Insight: Every U.S. state, Washington D.C., and Puerto Rico has reported mail theft-related check fraud, according to FinCEN. This isn’t a regional problem — it’s happening everywhere.
How to Protect Yourself From Check Washing and Mail Theft
The FBI and U.S. Postal Inspection Service recommend these steps:
Do This
- Drop outgoing mail inside the post office or a USPS collection box right before the last pickup
- Retrieve your mail as soon as possible after delivery
- Use USPS Informed Delivery to get email previews of incoming mail
- Use USPS Hold Mail when traveling
- Write checks with permanent gel ink pens (harder to wash than ballpoint)
- Fill out checks completely — leave no blank spaces on payee or amount lines
- Monitor bank statements and check images online regularly
- Consider switching to electronic payments (ACH, e-checks, mobile pay)
Never Do This
- Leave outgoing checks in your mailbox with the flag up overnight
- Write checks with erasable or regular ballpoint ink
- Put your Social Security number, credit card number, or driver’s license on checks
- Let mail accumulate in your box while you’re away
- Ignore unexpected missing mail — it could mean your checks were stolen
If you’re still writing paper checks, you need to treat every one like cash — because that’s exactly how criminals see them.— Steve Rhode

FAQ
What is check washing?
Check washing is a fraud technique where criminals use chemicals to erase the ink on a stolen check, then rewrite it with a new payee name and a higher dollar amount. The altered check is then cashed using counterfeit identification, and the victim’s bank account is drained for far more than the original check amount.
How do criminals get USPS arrow keys?
Arrow keys are stolen through robberies of mail carriers, burglaries of postal facilities, bribery of postal employees, or buying them on the black market. Between 2020 and 2024, arrow key thefts surged 150%, rising from 1,374 to 3,437 incidents — with recovery rates near zero.
How can I tell if my check was stolen from the mail?
Signs include: unexpected withdrawals from your bank account, checks cashing for amounts you didn’t write, checks cashed by payees you don’t recognize, or confirmation from your intended recipient that they never received your check. Sign up for USPS Informed Delivery to track what should be arriving in your mailbox.
Is check fraud covered by my bank?
Under the Uniform Commercial Code, banks generally must recredit your account for unauthorized check transactions if you report them promptly. However, the process can take weeks, and if you delayed reporting, your liability may increase. Contact your bank immediately if you suspect fraud.
Should I stop writing checks altogether?
Electronic payments (ACH transfers, online bill pay, mobile payment apps) are significantly harder for criminals to intercept than paper checks sitting in a mailbox. If you must write checks, use gel ink, drop them inside the post office, and monitor your account for unauthorized activity.
