A 45-year-old Chicago man who turned neighborhood mailboxes into his personal shopping aisle is headed to prison for four years after admitting to a burglary charge tied to a string of mail thefts on the Northwest Side.
Andrew Trotter pleaded guilty on Nov. 12 to one felony count of burglary in Cook County Circuit Court and will serve one year of mandatory supervised release after his prison term. Court records show he received credit for 62 days already served before sentencing, according to CBS Chicago. The case grew out of a U.S. Postal Inspection Service investigation that linked stolen debit and credit cards, a passport and other mail items back to him.
The U.S. Postal Inspection Service arrested Trotter on Sept. 15 during a joint operation with the Chicago Police Department. Officers say they recovered two counterfeit postal keys, several stolen debit and credit cards, a stolen passport and suspected methamphetamine from him at the time, Fox 32 Chicago reports. Prosecutors charged him with multiple felony counts of burglary, possession of burglary tools and possession of a controlled substance, along with misdemeanor counts for theft of mislaid property. Postal inspectors say they have tied him to multiple mailbox thefts on the Northwest Side dating back to early 2025.
Earlier arrests and an alleged pattern
Local reporting and prosecutors' statements indicate this was not Trotter's first run-in with inspectors over mailbox master keys. He was arrested in July on similar allegations after police say they recovered a counterfeit USPS master key along with a stash of stolen cards and IDs, CWB Chicago reported. That earlier case ended without prolonged detention because some of the charges were not detainable under Illinois pretrial rules at the time, according to local reporting. Prosecutors later connected evidence from that encounter to the broader investigation that set up the November plea.
Why arrow keys a prime target
Postal officials say counterfeit "arrow" or master keys are a prized tool in the mail theft world because they can open entire banks of residential mailboxes, giving thieves one-stop access to checks, cards, and personal information that can fuel identity theft schemes. In response, the U.S. Postal Inspection Service has increased enforcement in Chicago under its Project Safe Delivery initiative, the Postal Inspection Service reported. The agency and the Postal Service have been working to swap out outdated arrow locks for electronic systems and to step up key-accountability checks in an effort to make stolen keys less valuable to criminals. Officials say arrests and indictments like Trotter's are part of a larger push to protect customers and postal employees.
What happens next
Cook County court paperwork shows Trotter will be transferred to begin serving his four-year sentence, with credit for the 62 days already in custody. Prosecutors have said additional charges could be filed as the investigation continues, according to Fox 32 Chicago. Authorities are urging anyone who believes their mail may have been compromised to keep a close eye on financial statements and promptly flag suspicious activity for investigators. Postal inspectors and prosecutors say they are continuing to review leads and evidence in the case.
Anyone who believes they may have been the victim of mail theft can report it to the U.S. Postal Inspection Service at 1-877-876-2455 or online at USPIS, officials said. Local police and postal investigators also encourage residents to consider placing fraud alerts on their accounts and to report any suspicious mail or identity-related activity as soon as it appears.
