Where Did A.J. Johnson Go? Former Hamilton County Magistrate Left the Bench, Abandoned Judicial Race — and Now an Employment Mystery Emerges

MIA and false reporting to the Roll of Attorneys? Johnson, after a career spent helping Indiana's disciplinary establishment demand answers from other lawyers, framing them, serving requests for admission, he may appreciate better than most why unanswered questions have a way of inviting additional scrutiny.

NOBLESVILLE, Ind. — Aaron “A.J.” Johnson's rapid disappearance from Hamilton County's judiciary raises a straightforward question that still lacks a straightforward public answer: Why did he leave?

Johnson's trajectory had once been decidedly upward. After years working within Indiana's attorney-disciplinary system, he became a Hamilton County magistrate. Then, in July 2025, he announced that he was seeking the Republican nomination for Hamilton Superior Court 4 in the May 2026 primary.

Within months, both ambitions were over.

Johnson left his magistrate position and did not proceed with the judicial campaign he had announced. Yet despite the significance of those decisions, Hoosier Enquirer has been unable to locate a public explanation from Johnson establishing why he walked away from both positions.

Was it health? A better job? Family considerations? Politics? Pressure associated with his candidacy? Did Johnson simply decide that becoming an elected judge was no longer what he wanted?

Those questions should not be converted into conclusions without evidence. HE has found no reliable public evidence establishing that Johnson was seriously ill when he left the bench or withdrew from the race. Likewise, HE has found no evidence establishing that he was forced from the magistrate position.

What the available records do show is a strikingly abrupt change in professional direction.

FROM DISCIPLINARY LAWYER TO MAGISTRATE TO CANDIDATE

Johnson was hardly an unknown figure within Indiana's legal establishment.

Before becoming a Hamilton County magistrate, Johnson worked as counsel for the Indiana Supreme Court Disciplinary Commission, giving him experience inside the institution responsible for investigating allegations of attorney misconduct.

Hamilton County's judges subsequently selected Johnson to serve as a magistrate. An Indiana judiciary directory published while Johnson was serving confirms that he was among Hamilton County's magistrates.

Then came his next move: Johnson announced a campaign for Hamilton Superior Court 4.

An elected judgeship would have represented another significant advancement for an attorney who had already moved from disciplinary enforcement into judicial office. Instead, Johnson's judicial career abruptly went in the opposite direction.

He left the magistrate's bench. His campaign ended before the May 2026 Republican primary.

And there appears to have been remarkably little public discussion explaining either decision.

WAS JOHNSON SICK?

The recent retirement of Hamilton County Prosecutor Greg Garrison provides a useful contrast.

When Garrison retired, the public received an explanation: Garrison specifically cited serious health concerns. There was consequently little mystery about why a prominent Hamilton County official was leaving office.

HE has located no comparable explanation from Johnson.

That does not mean Johnson wasn't dealing with a medical or personal matter. Such matters can obviously remain private. It means only that HE has found no reliable public evidence allowing us to report illness as the reason for his departure.

The distinction matters. Questions are legitimate; speculation presented as fact isn't.

I he having his karma for all the lawyers he targeted and crucified? Why do the papers and news outlets gushed over his robing as the first coming of Jesus with "a deep legal background," which couldn't have been further from the truth? He was largely incompetent and the record of one case made the beyond clear. He didn't even know about the issue of separating witness prior to the start of a hearing.

He had failed to provide enough copies of his exhibits for the defense have one. The list goes on and on. He wasn't fit on day one or when a justice of the supreme court conducted his robing cermony as a Hamilton County Magistrate Judge.

Here s what is currently available on the Internet:

SO WHERE IS A.J. JOHNSON NOW?

That question produces an interesting answer — and another question.

The Indiana State Bar Association's online profile for Aaron Johnson, Indiana attorney number 26854-53, lists his professional organization as “MBCB Attorneys.” The profile identifies his professional address as 111 Monument Circle, Suite 3950, Indianapolis, and lists the firm's main telephone number.

Most significantly, the profile states that it was last updated June 11, 2026.

Johnson's Indiana law license is listed as "Active In Good Standing."

MBCB is Mattingly Burke Cohen & Biederman LLP, an Indianapolis commercial law firm. According to the firm's website, its lawyers practice in areas including business and corporate law, business litigation, creditors' rights, cybersecurity, data privacy and e-discovery, and risk management and dispute resolution.

The firm's own description emphasizes lawyers with backgrounds as business leaders, consultants, in-house counsel and attorneys at large law firms.

There is one problem.

Aaron Johnson does not currently appear on MBCB's publicly displayed “Who We Are” attorney roster.

Graduation records show he attended law school with one of partners of that firm.

MBCB Lawyer remains silent, but who likely knows something.

The firm's website identifies attorneys including Sean Burke, Hamish Cohen, Ray Biederman, Jon Mattingly, Brian Weir-Harden and others. Johnson's name is not among those presently displayed. So, where is Lorertta Rush hiding him? Calls to both have gone without any response.

That doesn't establish that Johnson doesn't work there. The Indiana State Bar Association profile points directly to MBCB, uses the firm's current Monument Circle address and telephone number, and was updated only this summer. Another public attorney directory, Avvo, likewise identifies Johnson's location as Mattingly Burke Cohen & Biederman LLP at the same Monument Circle address.

But the discrepancy deserves clarification.

Is Johnson presently employed by MBCB? Is he working there in an attorney, counsel, contract or other capacity that isn't displayed on the firm's website? Did he work there temporarily? Or is the State Bar profile outdated despite its June 11 update?

Those are questions that Johnson and MBCB could answer easily.

WHAT WE KNOW — AND WHAT WE DON'T

There is presently no public evidence located by HE establishing that Johnson resigned because he was sick.

There is likewise no public evidence establishing that Johnson was removed from the magistrate position, forced to abandon his judicial campaign, or left because of a criminal investigation. HE called for his resignation because of his history of completely criminal prosecutions of lawyers while unsupervised by the Commission or under its directions.

Complaints requesting federal and state investigation of Johnson's earlier disciplinary work were subsequently filed in April 2026. Filing a complaint, however, does not establish that authorities opened an investigation, much less that Johnson committed wrongdoing. The chronology also matters: Johnson's departure from the bench and campaign preceded those April complaints.

What can be established is unusual enough without embellishment.

Johnson worked inside Indiana's attorney-disciplinary machinery. He became a Hamilton County magistrate. He announced that he wanted voters to elect him judge. Then he left the bench and abandoned that campaign before voters ever got the opportunity to decide.

Now a State Bar Association profile updated June 11 places him at an Indianapolis commercial law firm whose own publicly displayed roster does not include him.

THE QUESTION REMAINS: WHY?

Public officials are entitled to private lives, and Johnson was not obligated to disclose private medical or family information merely because he changed careers.

But there is also a legitimate public-interest question when someone entrusted with judicial authority leaves that position and simultaneously abandons a campaign seeking even greater judicial authority.

Why did Aaron Johnson leave the Hamilton County magistrate's bench? Why no public statement or announcement? Where is he?

Why did he abandon his campaign for Superior Court 4? Was leaving the bench entirely his decision? Why has Rush said nothing or the justice who swore him in an unusual robing ceremony only otherwise done for Appellate Court Justices or other High Court Justices, not a lowly magistrate in a collar county.

Did the Hamilton County judges who had appointed him know that he planned to leave?

When did Johnson decide not to seek election?

And what exactly is his current professional relationship with Mattingly Burke Cohen & Biederman, if any? If so, why his name not on their website after many months of changing his address with the SCOIN to that firm. Do they represent him?

Those questions do not accuse Johnson of misconduct. They seek information about the unexplained departure of a former judicial officer and announced candidate for elected office.

Until Johnson, Hamilton County officials or another authoritative source supplies the missing explanation, the responsible answer remains surprisingly simple: we don't know why A.J. Johnson walked away.

And after a career spent helping Indiana's disciplinary establishment demand answers from other lawyers, framing them, serving requests for admission, Johnson may appreciate better than most why unanswered questions have a way of inviting additional scrutiny.
