Tucson, Arizona: City Prosecutor Matthew Walker Placed on Leave as Police Review Evidence in Lane Myers Case

The City of Tucson has placed City Prosecutor Matthew Walker on paid administrative leave while police investigate allegations of possible misconduct in the case that sent Tucson YouTuber Lane Myers to prison, the city announced on Thursday, Nov. 5.

City Attorney Roi Lusk placed Walker on leave pending the investigation, the city said. The allegations involve a probation revocation matter in a Pima County Attorney's Office case against Myers earlier this year, and that the investigation is independent of the City Attorney's Office.

What police are reviewing

KGUN 9 reported that Tucson 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. That is an allegation under investigation, not a finding. No charge against either Walker was reported in the city announcement or in the coverage published by Friday morning, and the Walkers say Myers harassed them.

The emails at the center of the review were sent to Shannon Walker, Matthew Walker's wife, and were part of the evidence in the county case against Myers. Matthew Walker testified about them in court.

How the new evidence surfaced

At an emergency hearing on Tuesday, Nov. 3, Pima County Deputy Attorney Rachel Stiles asked Superior Court Judge Douglas Metcalf to release Myers from prison after her office discovered what she called exculpatory evidence. Stiles said the new information raised questions about the integrity of evidence the judge had considered when he sentenced Myers to three years in prison about a month earlier, The Arizona Republic reported.

Tucson police served a search warrant at the Walkers' home on Monday, Nov. 2. Search warrant records show officers took multiple laptops, a router and several cell phones, two of them noted as belonging to Matthew and Shannon Walker, the Republic reported. Myers' attorney, Mark Resnick, told the Republic that county officials told him investigators had linked at least two emails from a Proton account to an internet address associated with the Walkers' home. Resnick said other Proton emails could not be traced because a virtual private network was used.

Prosecutors have not said which Walker the Proton account belonged to. The detective who sought the warrant wrote that he was seeking evidence to identify or exclude whoever created the account. Resnick said he left his Nov. 2 meeting with county officials under the impression the account was Matthew Walker's. Investigators have not confirmed that impression.

What happens next in the Myers case

Pima County Attorney Laura Conover said in a statement that her office alerts the defense and requests an emergency hearing when it learns of potentially exculpatory evidence, and her office said a new court date has been scheduled. At the Nov. 3 hearing, Metcalf ordered the state to move Myers from prison in Kingman to Pima County for an evidentiary hearing on Nov. 17, and said he could not vacate the sentence until that hearing.

Myers pleaded guilty in July 2025 to felony charges of stalking and harassing Shannon Walker, and his probation terms restricted what he could post about the Walkers. He was sentenced to three years in prison in early October after the judge found he had violated probation by posting videos about Shannon Walker.

When the Republic asked earlier this week whether Walker was still employed or on leave, a city spokesperson declined to comment and cited an ongoing investigation. Neither Matthew nor Shannon Walker responded to the Republic's request for comment. The city then announced the paid leave on Thursday.
