Sheriff Scott Maples Jr is deeply proud to announce that Assistant Chief Mark Grube has graduated as a member of the 296th session of the FBI National Academy.

The graduation took place at the National Academy in Quantico, Virginia, on December 11th, 2025.

Assistant Chief Grube is the 2nd officer in the Sheriff’s Office’s history to complete this prestigious program. Nationally, fewer than 1 percent of law enforcement officers are nominated and selected to attend the program. His journey began over five years ago and included rigorous background checks, academic requirements, and a lengthy selection process.

Assistant Chief Grube is proud to be one of two hundred and fifty-four law enforcement officers who graduated as part of the 296th session of the academy, which consisted of men and women from 47 states and the District of Columbia.

The class also included representatives from law enforcement agencies from 24 countries, members of four military organizations, and two representatives from federal civilian organizations. Assistant Chief Grube’s academic achievements were also complemented by 11 weeks of intense physical training, which culminated in the completion of the
grueling “Yellow Brick Road” 6.1-mile run and obstacle course, earning the Assistant Chief the prestigious Yellow Brick and a graduate certificate from the University of Virginia, which accredits all National Academy courses offered.

“It was an absolute honor to be part of FBI National Academy Session 296,” said Grube. “I trained, learned, and formed lifelong partnerships with the most incredible law enforcement executives in the world.”

Internationally known for its academic excellence, the National Academy offers 11 weeks of advanced communication, leadership, and fitness training. FBI Academy instructors, special agents, and other staff with advanced degrees provide the training; many instructors are recognized internationally in their fields. In the final challenge, Assistant Chief Grube earned his prestigious yellow brick by completing the 6.2-mile yellow brick road run and obstacle course.

A total of 56,688 graduates have completed the FBI National Academy since it began in 1935. The National Academy is held at the FBI Training Academy in Quantico, the same facility where the FBI trains its new special agents and intelligence analysts.

“Assistant Chief Grube’s graduation from the FBI National Academy is not just a personal
achievement but a milestone for our agency,” said Sheriff Maples. “His dedication, leadership, and commitment to excellence reflect the very best of the Clark County Sheriff’s Office, and his success strengthens our entire community.”

A Seymour man was struck and killed while walking in the southbound lanes of Interstate 65 late Sunday night.

Just after 11:25 p.m., the driver of a southbound bobtail Volvo semi-tractor reported to 911 that he believed he had struck a pedestrian walking along the fog line near mile marker 35, just north of Austin, Indiana.

The driver immediately pulled to the shoulder and contacted authorities. Deputies from the Scott County Sheriff’s Department and Jackson County Sheriff’s Department responded to the area and began searching for a possible victim, but initially located no one.

A short time later, as deputies continued their search, a southbound Ford Escape struck the pedestrian as he walked northbound in the driving lane approximately one-half mile north of the initial contact location.

The driver of the passenger vehicle immediately stopped and notified 911. Deputies responded to this second crash scene, and troopers from the Indiana State Police Sellersburg Post were then requested to the scene.

First responders transported the pedestrian, identified as Bryce Allen Sheaffer, 35, of Seymour, to Scott Memorial Hospital in Scottsburg, where he was pronounced deceased. Trooper Tate Rolfing, a crash reconstructionist with the Indiana State Police, responded to the scene and conducted the investigation.

Preliminary findings indicate the semi-tractor grazed Sheaffer initially.

Sheaffer continued walking northbound against traffic and entered the driving lane, where he was struck by the passenger vehicle several minutes later.

Neither alcohol nor drugs is suspected as a factor with either driver. Southbound lanes of I-65 were closed for the investigation until approximately 4 a.m. Monday.

The family of the deceased has been notified.

This crash remains under investigation by the Indiana State Police.

On December 16, 2025, the Indiana Internet Crimes Against Children (ICAC) Task Force served a search warrant on a residence on County Road 200 West in Jennings County, Indiana which resulted in the arrest of a 22-year-old North Vernon man, Tommy Jason Lee Dupuis.

As a result of the investigation, Investigators arrested Dupuis on a preliminary charge of Possession of Child Sex Abuse Material, Level 5 Felony.  He was incarcerated in the Jennings County Jail pending an initial appearance in court. 

The investigation is ongoing.  Additional arrests are possible.

This was an Indiana State Police investigation where detectives were assisted by task force members from the Jennings County Sheriff’s Office, the Clark County Sheriff’s Office, and the City of Jeffersonville Police Department. 

Between March and May 2025, Indiana State Police ICAC Investigators received four cybertips from the National Center for Missing and Exploited Children (NCMEC). These cybertips were reported to NCMEC by a social media platform that indicated that an unknown suspect was uploading images depicting child sexual abuse material to the application’s messenger service. 

Investigative efforts by state police detectives led them to South County Road 200 West, where members of the ICAC task force executed a search warrant at the residence this week.

Through the use of investigative and forensic methods, the suspect in the case was identified as Dupuis.

The Indiana ICAC Task Force is a multiagency task force that investigates and prosecutes persons who use the internet to exploit or entice children sexually. The Indiana State Police oversees the task force.

The Indiana ICAC Task Force encourages Hoosiers to report online exploitation, solicitation, and enticement-type crimes against children to NCMEC. The NCMEC website can be accessed through the ICAC Task Force website. To report a crime with your child as a victim involving the internet or other electronic means, please contact your local Indiana law enforcement agency.
