A City of Tucson prosecutor has been placed on paid administrative leave while Tucson police investigate allegations of possible misconduct in a probation case — including, according to reporting by KGUN 9, whether the prosecutor and his wife may have created evidence that helped send a man to prison. City Attorney Roi Lusk announced on Thursday, November 5, that City Prosecutor Matthew Walker is on paid leave pending the investigation, the City of Tucson said. The allegations, which have not been proven and have led to no charges, involve a Pima County Attorney’s Office probation-revocation case against Tucson YouTuber Lane Myers earlier this year.

The city said the police investigation is independent of the City Attorney’s Office. Lusk said Tucson police are in contact with the Pima County Attorney’s Office, and that he took the step to reassure the public that his office follows the rule of law and its ethical duties. A city spokesman said paid leave is standard during an investigation of this kind. No charges have been filed against Walker or his wife, and the claims against them remain allegations under investigation — not findings by any court.
According to the reporting on the investigation, police searched the Walkers’ home on Monday and took laptops, phones and a router, and the warrant return says at least two of the emails used as evidence against Myers came from an internet address tied to that home. KGUN 9 reported that police are looking into whether Walker and his wife, who is also an attorney, may have created evidence to make sure Myers would go to prison. The Walkers say Myers harassed them. Those competing accounts are now the subject of the police investigation, and Awaaz Punjab reports them as allegations only.
How a probation case reached this point
The dispute between Myers and the Walkers goes back to 2024, when Matthew Walker was involved in prosecuting cases against Myers, including an arrest after Myers was accused of disrupting a Tucson City Council meeting; those charges were later dismissed. In September 2024, Myers left a voicemail on the work phone of Shannon Walker — the prosecutor’s wife, who worked at the University of Arizona law school — complaining about her husband, and then began posting videos about her. She obtained an injunction against harassment, and Myers was indicted in part for violating it, according to reporting by The Arizona Republic on the case.
In July 2025, Myers pleaded guilty to felony charges of stalking and harassing Shannon Walker and was placed on probation, with conditions that barred contact with the Walkers and restricted what he could broadcast. He stayed in compliance for 11 months. In July 2026, probation officers took him into custody, accusing him of posting a fresh series of videos about Walker that prompted his followers to send her threatening emails. After a probation-revocation hearing before Pima County Superior Court Judge D. Douglas Metcalf — who rejected Myers’ argument that his posts were protected speech — Myers was found to have violated his probation and was sentenced to roughly three years in prison, with an expected release in 2028.
The emergency move by prosecutors
The case turned after prosecutors received post-conviction information about the evidence. Pima County Attorney Laura Conover said in a statement that her office alerts the defence and requests an emergency hearing when it learns of potentially exculpatory evidence, and the office said a new court date has been scheduled. Prosecutor Rachel Stiles filed an emergency petition asking the court to set aside Myers’ probation-violation finding and release him. At the hearing, Judge Metcalf said he could not release Myers directly from prison and that a hearing was required; he ordered Myers transferred from prison to the Pima County jail pending the November 17 hearing in Pima County Superior Court. KVOA reported Myers is expected to stay in custody until that hearing.

Nothing in this story has been decided against Matthew Walker or his wife. Police are investigating whether evidence was created; the Walkers say Myers harassed them; Myers’ attorney, Mark Resnick, says he expects the investigation to clear Myers of the email harassment — that is the defence’s position, not a court finding. No charges have been filed against the Walkers, and both sides are entitled to the presumption that the courts, not headlines, will decide what happened.
Why this matters beyond one courtroom
Probation cases turn on trust in evidence: a judge revokes a person’s liberty because the state presents proof that the rules were broken. When the allegation is that some of that proof may have been manufactured by people connected to the prosecution side, the consequences reach every case those officials have touched, and the Pima County Attorney’s Office — which prosecuted the revocation — is now the office that brought the new information to the court’s attention and asked for the conviction to be revisited. For Tucson residents, the city’s decision to place its own prosecutor on leave, with an investigation run by police independently of the City Attorney’s Office, is the institutional answer so far.
What happens next
Three tracks now run in parallel. First, the Tucson police investigation into possible misconduct continues, independently of the City Attorney’s Office and in contact with the Pima County Attorney’s Office; Walker remains on paid administrative leave while it runs. Second, Myers remains in custody at the Pima County jail ahead of his November 17 evidentiary hearing in Pima County Superior Court, where the court will decide what the new evidence means for his probation-violation finding and his prison sentence. Third, any decision on charges — against anyone — will follow the investigation, not precede it. Awaaz Punjab will update this story after the November 17 hearing and if charges or official findings are announced.
