Key Points and Summary – The U.S. Postal Inspection Service (USPIS), America’s oldest federal law enforcement agency, is offering a reward of up to $100,000 for information regarding a burglary at the Grand Tower Post Office in Illinois on December 18, 2025.

$100,000 Reward Offered: USPIS Seeks Public Help Solving Grand Tower Post Office Burglary
Although not as famous as the Federal Bureau of Investigation (FBI) or US Secret Service, not as controversial as Immigration & Customs Enforcement (ICE; for whom I worked for two years as a Special Agent, so feel free to hate me) and US Customs & Border Protection (CBP; I was a CBP Officer at Los Angeles/Long Beach Seaport for three years, so again feel free to hate me), the US Postal Inspection Service (USPIS) is actually America’s oldest Federal law enforcement agency.
In fact, USPIS celebrated its 250th anniversary back on August 7, 2025, which means its existence predates the Declaration of Independence (as does the start of the Revolutionary War, but that’s a different story).
And right now, USPIS is asking for your help (as in the general public’s).
USPIS Request for Assistance
This request for assistance comes to our attention via the website for WPSD-TV Local 6, the NBC affiliate for Paducah, Kentucky, in a January 6, 2026, report by Alexis Barrett, titled “US Postal Inspection Service offers up to $100,000 for information leading to a conviction.”
To wit: “The US Postal Inspection Service is offering a reward for information leading to an arrest and conviction after a burglary in mid-December … According to USPIS, the Grand Tower Post Office—located at 522 Front St, Grand Tower, IL 62942—was burglarized on December 18, 2025 … The US Postal Inspection Service warns the public not to apprehend the individual themselves but to contact the service at 1-877-876-2455, say ‘law enforcement,’ and reference Case No. 4641750. All information will be kept strictly confidential.”
Types of Careers in USPIS
–Postal Inspectors: These are the criminal investigators/special agents of USPIS. (Going back to my aforementioned stint as an ICE Special Agent, during one particular case on which I was the lead agent.
I learned that, by regulation, only USPIS Postal Inspectors are allowed to go undercover as uniformed postal mail carriers.) They have investigative jurisdiction in all criminal matters involving the integrity and security of the US Postal Service, investigating criminal, civil, and administrative violations of mail-related laws.
Newly hired Postal Inspector candidates go through a rigorous 16-week training course at the William F. Bolger Center in Potomac, Maryland. This training program includes academics, firearms, defensive tactics, physical fitness, and practical exercises (much like the Criminal Investigator Training Program [CITP] at the Federal Law Enforcement Training Center [CITP] in Glynco, Georgia).
–Postal Police Officers: These are the uniformed cops of USPIS (somewhat analogous to the Uniformed Division [UD] of the Secret Service), performing a variety of duties pertaining to the security of postal buildings, personnel, property, mail, and mail-in-transit.
Postal Police Officer Basic Training is also held at the Bolger Center and lasts 12 weeks.
-Professional, Technical, and Administration: As per the USPIS Careers main page, “The Postal Inspection Service has outstanding career opportunities for professional, technical, and administrative staff. These specialists and analysts provide integral support to investigations and the agency’s mission.” (I myself worked briefly as a USPIS Intelligence Analyst at the agency headquarters in L’Enfant Plaza, Washington, DC, back in 2020.)
One Famous USPIS Case
Alvin Karpis and the Barker-Karpis Gang: Though as (in)famous as other gangsters of the 1920s and 1930s such as John Dillinger, “Baby Face” Nelson, and “Pretty Boy” Floyd, Alvis Karpis was nonetheless designated as Public Enemy No. 1 in 1935 by FBI founding director J. Edgar Hoover after he and his gang robbed a passenger and mail train near Garrettsville, Ohio using Thompson submachine guns, pistols, and dynamite, making off with $34,000 in cash and $11,650 in bonds (equivalent of over $1,000,000 today).
Six months after the incident, Post Office inspectors teamed with Hoover’s agents to track down Karpis and his accomplices in New Orleans.
More than a dozen Federal law enforcement officers swarmed Karpis’s car and took him into custody.
He would end up serving 26 years at Alcatraz Prison off San Francisco, and then was transferred to Leavenworth Penitentiary when Alcatraz closed. Karpis was released on parole in 1969 and deported to Montreal, Canada.
(The Karpis caper is dramatized in the 1974 film “The F.B.I. Story: The FBI Versus Alvin Karpis, Public Enemy Number One,” wherein Hoover is portrayed by the late great Harris Yullin, whom movie buffs will also recognize as corrupt Miami police detective Mel Bernstein in the iconic 1983 film “Scarface” starring Al Pacino and Michelle Pfeiffer.
USPIS Weaponry
According to the most recent information I have available, the standard-issue sidearm for USPIS Postal Inspectors and Postal Police Officers alike is the SIG P229 DAK (Double Action Kellerman) .40-caliber semiautomatic pistol, which, coincidentally, is the same gun I was issued as an ICE Agent.
