Quick Answer: A Missouri postal carrier was sentenced to one year and one day in prison for selling her USPS “arrow key” and stealing checks from the mail over a year-long period. Her co-conspirator used the stolen checks to attempt $1.2 million in fraudulent deposits. She was paid in cash, CashApp transfers, and groceries.
Your mail is only as safe as the person carrying it. And in one St. Louis suburb, the person carrying it was selling the key to your mailbox for cash and groceries.
What Happened
According to the U.S. Attorney’s Office for the Eastern District of Missouri, Cambria M. Hopkins, 30, of Florissant, Missouri, was sentenced on January 30, 2026 for her role in a conspiracy to steal checks from the U.S. mail.
Hopkins was a mail carrier based at the Clayton, Missouri Post Office. Here’s the timeline, based on her guilty plea and court records:

- March 20, 2022: Hopkins sold her USPS “arrow key” to co-conspirator Malik A. Jones for cash
- March 2022: She told Jones exactly which collection boxes her key would open
- August 2022 – August 2023: Hopkins sold stolen checks to Jones multiple times over a full year
- Payment: Jones paid her in cash, CashApp transfers, and groceries
- January 30, 2026: Hopkins sentenced to one year and one day in prison, ordered to repay $21,635
How the Arrow Key Scheme Worked
Every USPS mail carrier has an “arrow key”—a master key that opens blue collection boxes and cluster mailboxes. It’s the key to your mail.

How It Worked: According to the USPS Office of Inspector General, Hopkins didn’t just sell her key—she gave Jones a map. She told him which specific collection boxes her key would open. Jones then paid others to use the key to steal mail from those boxes. Hopkins also stole checks directly from mail on her route and from inside the Post Office, and sold those to Jones separately.
Once Jones had the checks, he altered and counterfeited them, then arranged for deposits into various bank accounts before withdrawing the funds. Investigators say Jones attempted to deposit forged and counterfeit checks with a face value of $1.2 million—though many were flagged and rejected by banks.
Jones, 28, was sentenced in September to three and a half years in prison on charges of bank fraud and aggravated identity theft.

This Isn’t an Isolated Case
Mail theft-related check fraud is a nationwide problem that’s been getting worse:
- The FBI reported that suspicious activity reports related to check fraud nearly doubled from 2021 to 2023
- FinCEN received more than 15,400 reports from 840+ financial institutions in just six months, totaling $688 million in suspicious activity tied to mail-stolen checks
- One conspiracy in North Carolina involved $24 million in stolen checks, including $8 million in U.S. Treasury checks
- Robberies targeting postal workers for their arrow keys have increased significantly since 2017
How Stolen Checks Become Cash: According to the FBI, criminals use stolen checks in several ways: 44% alter and deposit them directly, 26% use them as templates to create counterfeits, and 20% simply sign and deposit them as-is. Many avoid banks entirely by using mobile deposit apps and ATMs.
True Crime Connection: Not long ago, I covered a check-stealing scheme with help from postal service employees on my True Crime podcast at TrueCrimeUnheard.com. The people behind it got caught that time too—but the podcast episode is worth a listen if you want to understand how organized these operations really are.
How to Protect Your Mail
The FBI and U.S. Postal Inspection Service recommend:
- Don’t leave outgoing mail in your mailbox overnight. Use the letter slots inside your local Post Office instead.
- If using a blue collection box, drop mail as close to the posted pickup time as possible—not the night before.
- Use indelible black ink pens (like gel ink) when writing checks. It’s harder for criminals to “check wash”—using chemicals to erase the payee name and amount.
- Sign up for USPS Informed Delivery. You’ll get daily email previews of incoming mail, so you’ll know if something doesn’t arrive.
- Monitor your bank statements. Look for checks you didn’t write or amounts that don’t match.
- Consider electronic payments when possible—no paper means nothing to steal.
- Retrieve mail promptly. Don’t let delivered mail sit in your box.
