SALT LAKE CITY, Utah — A months-long 2News investigation has uncovered sharp contrasts in how two local government agencies responded to allegations of an inappropriate relationship between a Salt Lake County prosecutor and a West Valley City police detective.
At the center of the controversy are Salt Lake County Deputy District Attorney Adrianna Davis and West Valley City Police Detective Josue Llil. While the Salt Lake County District Attorney’s Office has consistently dismissed the allegations as “salacious and unsupported,” internal records show that West Valley City Police took the matter far more seriously.
According to documents obtained by 2News, West Valley City’s Professional Standards Section — also known as Internal Affairs — launched a formal investigation into Detective Llil’s conduct. The investigation concluded with a finding of “Conduct Unbecoming of an Officer.” On April 28, Police Chief Colleen Jacobs issued a disciplinary Letter of Reprimand to Llil, underscoring the department’s stance on the matter.
This development stands in stark contrast to the response from Salt Lake County District Attorney Sim Gill, whose office has repeatedly dismissed the allegations. Critics say the DA’s office failed to appropriately address or investigate the potential conflict of interest or ethical concerns raised by the alleged relationship.
Former Deputy District Attorney Meghann Mills, who once worked under Gill, came forward as a whistleblower, alleging a systemic effort within the office to suppress the truth. “People in power, people that I trusted were corrupt,” Mills told 2News Investigates. “They were willing to disregard the truth.” Mills said she reported the alleged misconduct to Gill and his administration directly. Frustrated by what she described as a cover-up, she ultimately resigned from her position.
Mills praised the West Valley City Police Department for conducting a fact-based investigation and taking disciplinary action. “West Valley City — clearly their focus was what are the facts and what’s the right thing to do,” she said.
The diverging responses from the two agencies have raised concerns among legal experts and community members about oversight and accountability within the District Attorney’s office. The case continues to draw attention as calls grow louder for an independent review of the DA’s handling of internal misconduct allegations.
