Top Missouri Prosecutor Found Dead Inside Courthouse

A longtime Missouri prosecutor was found dead inside the courthouse where he had spent more than two decades pursuing criminal cases — just months before he was preparing to leave offic

Platte County Prosecuting Attorney Eric Zahnd, 53, died at the Platte County Courthouse on Thursday, September 17, prompting authorities to clear and close the building while investigators responded.

The Platte County Sheriff’s Office confirmed Zahnd was the person who died and said there was no threat to the public.

The courthouse closed around 2:15 p.m. Thursday and remained closed Friday before reopening Monday.

Authorities have not publicly released an official cause or manner of death.

That distinction is important because some media reports have described Zahnd’s death as a suicide. As of September 22, however, local law enforcement says additional information will be released after it becomes available from the medical examiner.

Zahnd Was Under Criminal Investigation Before His Death

A day after Zahnd’s death, another major development emerged.

The Missouri State Highway Patrol confirmed its Division of Drug and Crime Control was conducting an active investigation into criminal allegations involving Zahnd.

According to the Highway Patrol, the Platte County sheriff requested the investigation on June 15. The agency has not disclosed the precise allegations and says the investigation remains active.

There has been no official finding that Zahnd committed a crime.

The Highway Patrol has also not publicly established any connection between its investigation and his death.

Zahnd’s family addressed the controversy Monday, saying speculation surrounding the investigation had grown following his death.

According to the family, the inquiry involved Zahnd’s use of his county email account to indicate that he would not support a candidate’s reelection campaign. The family acknowledged that using the account that way was a mistake but disputed suggestions of more serious wrongdoing.

The Highway Patrol has not confirmed the family’s description of the investigation, saying it will not discuss details while the inquiry remains active.

Family Opens Up About Mental Health Struggles

Zahnd’s family also revealed that the pressures of his longtime position had taken a toll on his mental health.

In a statement released September 21, the family said Zahnd had begun developing plans to seek help and eventually use his experience to help others.

They said he had privately decided it was time to close the chapter on his career as Platte County prosecutor after acknowledging that the job had brought him both enormous satisfaction and significant personal pain.

The family urged the public not to assume the Highway Patrol investigation explained his death and asked for privacy while they grieve.

Law enforcement has not announced an official cause of death.

He Had Already Announced His Retirement

Zahnd’s departure from office had actually been planned months earlier.

On March 31, he withdrew his reelection bid shortly before Missouri’s filing deadline, and on April 1 he publicly announced that he intended to retire after more than 23 years as Platte County’s top prosecutor.

Zahnd said at the time that he and his wife, Tracy, had been discussing an “exit plan” for years.

He said he hoped to spend more time with his family, including his two adult sons, one of whom was studying law and another pursuing a doctorate at the University of Missouri.

Zahnd also endorsed his longtime first assistant, Mark Gibson, to succeed him.

Following Zahnd’s death, Gibson was named interim prosecuting attorney. He is expected to run the office until Missouri Gov. Mike Kehoe appoints a permanent replacement.

More Than Two Decades as Platte County Prosecutor

Zahnd was first elected Platte County prosecuting attorney in November 2002 and took office in January 2003.

At the time of his death, he was the longest-serving prosecutor in Platte County history and the longest-tenured elected prosecutor serving in the Kansas City metropolitan area.

His office handled everything from traffic offenses and child-support enforcement to sex crimes and first-degree murder cases.

Zahnd also became involved in shaping Missouri criminal law.

According to his official county biography, he helped push through legislation increasing penalties for repeat drunk drivers and advocated for Missouri’s version of Jessica’s Law, which imposed severe penalties for certain sex offenses against children.

He also helped write a 2009 law requiring law enforcement to record interrogations in certain serious felony investigations and supported a constitutional amendment involving evidence of prior criminal acts by repeat child sex offenders.

He was named Missouri Prosecutor of the Year in 2014.

Earlier this month, the Missouri Association of Prosecuting Attorneys presented Zahnd with its President’s Award, the organization’s highest honor, recognizing his years in the profession.

Prosecutor’s Office Reopens Without Him

The courthouse reopened Monday, four days after Zahnd’s death.

Gibson said grief counselors and mental health professionals were made available to employees as staff returned to work.

The office had already been grieving another loss after longtime assistant prosecutor Kaitlynn Donnelly died from cancer earlier this year.

Despite the upheaval, Gibson said criminal cases and services for victims would continue.

Zahnd’s funeral is scheduled to affect county operations again Thursday, September 24. Platte County’s Recorder of Deeds office has announced it will close for several hours that morning in recognition of the service.

Meanwhile, two separate investigations remain unresolved: the sheriff’s investigation into Zahnd’s death and the Highway Patrol’s investigation into the allegations involving him.

Neither agency has publicly announced when additional findings will be released.
