Why Hire a Former Prosecutor? We built these cases. Now we dismantle them.

The Benefits of a Former Prosecutor on Your Side

A lot of Phoenix criminal defense firms will tell you they have former prosecutors on their team. Fewer will explain what that actually means for you.

It is not about familiarity with the courtroom or knowing prosecutors on a first-name basis. The real advantage is that a former prosecutor understands the system from the inside, at the decision-making level. They know which cases the prosecution considers strong and which ones they consider risky to take to trial. They know what evidence is genuinely damaging and what collapses under pressure. They know how to talk to a charging attorney because they have been a charging attorney.

At MayesTelles PLLC, that experience is not a talking point. It is the reason we built this firm.

The Pre-Charge Window — Where Cases Are Actually Won

Most people believe criminal cases are decided at trial. The reality is that the most important phase of your case is the window between when law enforcement first contacts you and when a prosecutor decides whether to file charges. That window can be hours or weeks. And what happens in it can determine everything.

In Maricopa County, a prosecutor reviews the detective's report and makes a judgment call. Charges get declined when the evidence is weak, when a witness is unreliable, or when constitutional questions cloud the investigation. Former prosecutors know exactly what triggers a declination — because they made those calls themselves.

David Telles prosecuted cases at the Maricopa County Attorney's Office. Mark Mendoza rose to Bureau Chief there, which means he was not just filing cases — he was training the current generation of Maricopa County prosecutors on how to evaluate them. James Simpson ran a Major Crimes unit and a High Intensity Drug Trafficking Area unit at the Attorney General's Office. When these attorneys approach a charging attorney on behalf of a client during an active investigation, they are not asking from the outside. They are speaking the language of the institution, from years of experience inside it.

That is why pre-charge intervention works at MayesTelles in ways it does not at other firms. It is a different kind of conversation entirely.

Reading a Police Report the Way the Author Reads It

Former prosecutors do not read police reports the way most defense attorneys do. They read them the way the people who wrote them do — and they know exactly where those reports fall apart.

They know which field sobriety tests have documented failure rates. They know which forensic procedures have chain-of-custody vulnerabilities. They know that a detective's report is not a neutral document — it is a narrative built toward a conclusion, and every narrative has gaps.

Melanie Laboy adds a perspective that almost no other attorney in Arizona brings: she has served as a Judge Pro Tem for the Maricopa County Superior Court. She has reviewed the same motions, the same evidence, the same arguments — from the bench. She knows how judges actually weigh what is put in front of them, and she prepares cases accordingly.

Chris Culbert, who leads the DUI division, is a retired Scottsdale Police Department officer. When he challenges a DUI arrest, he is not arguing from a legal textbook — he is auditing the arresting officer's performance against the same training manuals both of them know.

What This Means for Your Case

It means your attorney sees the prosecution's strategy before it unfolds. It means they know which arguments will move a charging attorney and which ones won't. It means they walk into a negotiation with the same institutional knowledge as the person across the table — and sometimes more of it.

It also means they know when to fight and when to negotiate, and they make that judgment based on real experience rather than instinct. As David Telles says, for the attorneys at MayesTelles, it is all about winning for their clients. That means knowing when the State's case is strong enough that a negotiated outcome serves the client better — and knowing when it is weak enough that fighting is the right call.

And regardless of how a case resolves, every case at MayesTelles is prepared with a trial-ready posture from day one. That preparation is not just for the courtroom — it is what forces the State to confront weaknesses early, creates motion hearings that can narrow or exclude evidence, and signals that this firm will not accept a bad outcome out of fear. Prosecutors who know your attorney is prepared for trial negotiate differently than prosecutors who assume you will take whatever they offer.

“James Simpson picked my case apart and went through it with a fine-toothed comb finding inconsistencies throughout. I went from facing over a decade in prison to a term of probation. I know for a fact that the state prosecution does not like to see that combination of experience sitting on the other side of the table.”
