Indiana police chief arrested on felony charges after feds seize more than 100 guns from his home
Federal agents and county police raided the Merrillville, Indiana, home of New Chicago Police Chief Earl Mayo on Friday, seizing more than 100 firearms before arresting him across state lines in Ohio. By Sunday, Mayo faced charges of misconduct, obstruction of justice, theft, and unlawful possession of an anabolic steroid, a cascade of felony allegations that forced state law enforcement to take over policing duties in the tiny town he was sworn to protect.
The arrest adds another ugly chapter to the long-running saga of law enforcement corruption in Lake County, Indiana, a jurisdiction that sent its previous sheriff to federal prison and whose current sheriff is under scrutiny for nearly $300,000 in allegedly misspent jail funds.
It also lands squarely in the lap of Mayo's father, Jerry Williams, an Indiana State Police major who recently won the Lake County Democratic primary for sheriff and will appear on the ballot this November.
The raid and the arrest
Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives, working alongside county police, executed search warrants at Mayo's residence in Merrillville on Friday. Inside, they found the massive cache of firearms, more than 100 guns, along with anabolic steroids, the New York Post reported.
Mayo was not home when the warrant was served. He was picked up around 6 p.m. Friday in Clark County, Ohio, roughly 250 miles east of his Indiana jurisdiction. Why he had crossed state lines ahead of the arrest remains unexplained. Authorities expect him to be extradited back to Lake County to face the charges filed there.
By Friday evening, the New Chicago Police Department had effectively ceased to function under its own leadership. The Lake County Sheriff's Department stepped in to assume all policing duties for the community.
A town of 2,000 left without its own police force
New Chicago is a speck on the map, less than one square mile, tucked just west of Lake Station, home to roughly 2,000 residents. It is the kind of place where a police chief's arrest doesn't just make headlines. It removes the entire law enforcement apparatus.
Lake County Sheriff Oscar Martinez moved to reassure residents. He told the NWI Times that his department's takeover centered around a "matter that remains under investigation" and said there was "no need for the citizens of New Chicago to worry" about a gap in law enforcement coverage. Martinez did not respond to messages from the Post.
For a community that small, the reassurance may ring hollow. When your police chief is hauled away in handcuffs and your department is absorbed overnight by the county, the disruption is not abstract. It is the patrol car that used to sit on your block now belonging to someone else's chain of command.
What the charges mean, and what remains unclear
Breitbart reported that Mayo faces felony allegations tied to the sale of guns from an evidence room, adding a sharper edge to the misconduct and theft charges. The sheer volume of firearms recovered, more than 100, raises obvious questions about where they came from and how long they had been accumulating.
The specific nature of the obstruction of justice charge has not been detailed publicly. Nor has the timeline of the federal investigation that led to the ATF's involvement. It was not clear by the time of publication whether Mayo had retained an attorney.
The steroid possession charge, while less dramatic than the firearms allegations, adds another layer. A sitting police chief found with anabolic steroids in his home is not a minor footnote. It speaks to a pattern of conduct that investigators apparently found serious enough to include in the charging documents.
A family caught in the fallout
The arrest puts Jerry Williams, Mayo's father, in an extraordinarily difficult position. Williams is not some distant relative. He is a sitting Indiana State Police major, a career law enforcement officer, who just secured the Democratic nomination to run for Lake County sheriff in November.
Williams released a statement Saturday that tried to balance parental loyalty with institutional credibility:
"We raised all of our children with love, guidance and a strong foundation of values. We've always held our children to higher standards, as we have ourselves."
He acknowledged the gravity of the situation without conceding guilt:
"We are aware there are allegations that are troubling, and we struggle to reconcile them with the values we worked so hard to instill in all of our children and grandchildren."
Williams went further, stating that if the allegations prove true, his son "must and should accept responsibility for his actions and face the consequences." He also invoked the presumption of innocence, saying Mayo should be "presumed innocent unless and until proven otherwise."
The statement was carefully worded. But no amount of careful wording changes the political math. A Democratic sheriff candidate whose own son, a police chief, stands accused of stealing firearms, obstructing justice, and possessing steroids will face questions that no press release can answer. Voters in Lake County will decide whether the father's record can survive the son's alleged conduct.
Lake County's long history of law enforcement scandal
This is not the first time Lake County has watched a law enforcement leader face serious criminal charges. The county's track record is, by any honest measure, grim.
Former Lake County Sheriff John Buncich was convicted in 2018 on federal bribery and fraud charges. Prosecutors proved he ran a "pay-to-play scheme," accepting more than $32,000 in cash and campaign donations from tow truck operators in exchange for favorable treatment. A federal judge sentenced him to 15 years in prison. When federal authorities pursue corruption at the local level, the cases tend to reveal rot that runs deeper than any single official.
The current sheriff, Oscar Martinez, has his own problems. A state audit released earlier this year accused Martinez of improperly spending nearly $300,000 from the local jail's commissary fund. The money allegedly went to golf outings, travel, and church donations, none of which are standard line items in a jail budget.
Now add a police chief arrested with more than 100 guns, steroids, and a stack of felony charges. Lake County's law enforcement establishment is not inspiring confidence.
A pattern that demands accountability
The question for Lake County residents, and for Indiana more broadly, is whether any of this will produce lasting reform or just another cycle of indictment, conviction, and replacement by the next person in line. Buncich went to prison. Martinez faces audit findings. Mayo now faces criminal charges. The institutions keep producing the same failures.
Accountability in law enforcement is not a partisan issue. Officers who abuse their authority undermine public trust in ways that hurt every community, regardless of politics. When a law enforcement officer faces criminal charges, the system must treat the case with the same rigor it would apply to any citizen, no more, no less.
But the pattern in Lake County suggests something systemic. A county of more than 500,000 people, Indiana's second most populated, keeps cycling through leaders who end up on the wrong side of the law. At some point, the problem is not just the individuals. It is the culture, the oversight, and the political machinery that elevates them.
The charges against Mayo remain allegations. He has not been convicted. His father's call for a presumption of innocence is legally correct. But the facts already on the record, the ATF raid, the 100-plus guns, the steroids, the charges filed, the entire police department shuttered overnight, paint a picture that no presumption can erase from public view.
Cases like this one echo across the country wherever misconduct allegations entangle public officials and the institutions they serve. The damage is never limited to one person. It radiates outward, to the officers who served honorably under a compromised chief, to the residents who trusted their department, and to the broader public that watches another badge get tarnished.
What comes next
Mayo is expected to be extradited to Lake County. The investigation remains active. The ATF's involvement signals federal interest that may extend beyond the charges already filed.
For New Chicago, daily life will continue under the Lake County Sheriff's Department for the foreseeable future. For Jerry Williams, the November election just got considerably harder. And for Lake County voters, the question is the same one it has been for years: who can they actually trust to wear the badge?
When the people hired to enforce the law keep breaking it, the citizens who play by the rules are the ones left holding the bill. Lake County has paid that bill before. It appears they are about to pay it again.
