Missouri State Highway Patrol director recounts Macon lab error, closure and system reforms
Loading...
Summary
Laboratory director Brian Hoey described a data‑review error in a Macon drug chemistry lab that led to an internal investigation, termination of an examiner and the lab's closure; he said the agency has added QC checks, is centralizing data and expanded leadership and communication practices to reduce future risk.
Brian Hoey, director of the Missouri State Highway Patrol crime laboratory division, told a national webinar audience that a misread chromatograph and subsequent personnel conflict at the agency's Macon drug chemistry laboratory prompted an internal investigation, the termination of an employee and the lab's closure.
Hoey described the technical trigger as a peak appearing in a blank sample on a gas chromatography–mass spectrometry run. He said a reviewer clicked to the side of the peak so the mass spectrum did not capture the full ion pattern and therefore did not confirm THC. Hoey cited retention times of approximately 9.361 and 9.417 milliseconds on slides used in the presentation to illustrate how a close but incomplete scan produced an misleading result.
"The image of me sitting in front of a senate panel answering the question, what did you know and when did you know it?" Hoey said, describing the reputational stakes that drove the agency's response.
Hoey said the Macon laboratory was a two‑person operation — a supervisor and a drug chemist — and that the two employees did not get along. After confrontation about the blank, Hoey said the chemist "lied" during internal interviews; the issue was referred to the patrol's professional standards division and an investigation followed, culminating in the employee's termination.
To check whether the problem was isolated or systemic, the agency used a statistically based sampling plan. Hoey said the drug chemistry technical leader applied a hypergeometric sampling method across the agency's 31 drug chemists to review casework and look for protocol drift or other systemic errors.
Interviews and root‑cause work, he said, showed that the anomalies reflected both human and situational factors. "More importantly," Hoey said, "we discovered that our process—situation problem, not people—were contributing to the anomalies and errors." As a result, the Patrol added quality‑control measures, tightened data review practices and began exploring instrument networking and a central data repository.
Hoey said the agency closed the Macon laboratory "last June" and offered transfer options to the remaining supervisor, who requested and completed a transfer to the Springfield laboratory and is "flourishing," he said. He added that implementing new QC practices has increased backlog and turnaround times, which the agency continues to manage.
To improve communication and reduce complacency, Hoey described new monthly "meet the manager" WebEx sessions that allow employees at multiple levels to ask questions directly of management. He also said the agency operates an internal leadership course modeled on a military leadership program and encourages staff to participate.
Hoey framed the episode as a change management challenge and invoked Kotter and other authorities on organizational change: establish urgency, communicate a clear "why," assemble buy‑in and make changes stick by iterative evaluation. He told participants the agency is transitioning from a homegrown laboratory information management system to a commercial off‑the‑shelf product to reduce reliance on paper archives and inconsistent instrument software versions.
During a moderated Q&A, Hoey acknowledged leadership shortcomings in not responding sooner to the Macon supervisor's reports, saying organizational complacency and failure to support frontline staff were barriers. He said the agency is still working through uncertainty and cultural change roughly 18 months after the incident.
The webinar concluded with a reminder that the Patrol's reforms are ongoing: centralize data, increase QC, broaden communication channels and train leaders to detect and respond to systemic risk. Hoey closed by urging continuous improvement "so we are not going to be the next Netflix special," and invited participants to follow posted contacts and resources for more detail.
