Osage County, Oklahoma

Oklahoma’s Largest County

Oklahoma map

At the Osage County Sheriffโ€™s Office, our mission is to provide a solid foundation on which the residents of Osage County can thrive. We are committed to building public trust and fostering safe, secure communities through professional, high-quality professional law enforcement.

Osage County holds a unique place in Oklahomaโ€™s history and geography. As the stateโ€™s largest county by area, it was established in 1907 when Oklahoma gained statehood. The countyโ€™s name and heritage are deeply tied to the federally recognized Osage Nation, whose reservation boundaries are coextensive with the county itself. This land became the Osage Nation Reservation in the 19th century following the relocation of the Osage people from Kansas.

The county seat, Pawhuska, is one of the first three towns founded in the county and remains a hub of history and culture. As of the 2020 Census, Osage County had a population of 45,818 residents.

According to the U.S. Census Bureau, the county spans an impressive 2,304 square miles (5,970 kmยฒ), with 2,246 square miles (5,820 kmยฒ) of land and 58 square miles (150 kmยฒ) of water, accounting for 2.5% of its total area. Much of the landscape is part of the Osage Plains, characterized by open prairie, while the eastern portion features the rolling Osage Hillsโ€”an extension of Kansasโ€™ Flint Hills. Nature enthusiasts can also explore the renowned Tallgrass Prairie Preserve, located just north of Pawhuska, where remnants of the once-vast tallgrass ecosystem are carefully preserved.

On Friday night, September 18, 2026, the Osage County Sheriffโ€™s Office received information that a wanted individual was staying at a residence in the 600 block of North Cosden Avenue in Shidler.

Osage County Dispatch confirmed that Seneca Thomas, 40, was wanted out of Kay County on an outstanding felony warrant in Case No. CF-2021-00070, involving a charge of Trafficking in Illegal Drugs, with bond set at $400,000.

At approximately 11:30 p.m., an Osage County Deputy located Thomas at an apartment in the 600 block of North Cosden and took her into custody without incident.

Thomas was subsequently transferred to the custody of the Kay County Sheriffโ€™s Office and transported to the Kay County Detention Center.

This is an arrest not a conviction.

The Osage County Sheriffโ€™s Office has arrested Larry Dale Todd Jr., 52, following an investigation into a shooting that occurred on September 10, 2026, near Heritage Hills Drive in Sand Springs, Osage County.

Deputies responded to the area after Osage County Dispatch received a 911 call reporting a shooting. The victim reported that Todd drove him to a residence, retrieved a black handgun, and fired one round at him while he was seated in the back seat of a Chevrolet pickup.

The victim was not struck by the bullet but sustained injuries from broken glass after the projectile entered the vehicle through the window near where he was seated.

A witness at the scene also identified Todd as the alleged shooter and directed investigators to the area where the shot was reportedly fired. Deputies recovered a .45-caliber shell casing in that area.

During the investigation, deputies obtained and executed a search warrant at the residence. Investigators located a black in color Colt handgun matching the description provided during the investigation inside a locked bedroom associated with Todd.

Todd was arrested in connection with the incident on a complaint of Shooting with Intent to Kill. Todd was booked into the Osage County Detention Center and was officially arraigned on September 14, 2026, through the Osage County District Court and is being held on a $150,000.00 bond.

All defendants are presumed innocent unless and until proven guilty in a court of law.

A Career of Service: Environmental Deputy David McAlister Retires

After more than 16 years of service to the citizens of Osage County, Environmental Deputy David McAlister will retire from the Osage County Sheriffโ€™s Office on September 15, 2026, leaving behind a unique legacy of protecting not only the people of Osage County, but also its land and waterways.

McAlister began his law enforcement career with the Osage County Sheriffโ€™s Office in 2009 as a Reserve Deputy. In March 2010, he transitioned into a part-time position as a Courthouse Deputy.

His career would eventually take a different and specialized direction. In 2014, the Sheriffโ€™s Office, working with the Osage County Board of County Commissioners, established an Environmental Deputy position funded through a grant from the Oklahoma Department of Environmental Quality. Created during the administration of Sheriff Ty Koch, the position recognized the need for a dedicated investigator who could focus on illegal dumping, pollution, environmental crimes, and the cleanup of contaminated areas throughout Osage County.

McAlister took on that responsibility and made the position his own.
Over the years, he successfully investigated and prosecuted numerous environmental cases, issued citations, and held violators accountable under Oklahoma law. As environmental laws and enforcement efforts evolved, McAlister remained committed to ensuring Osage County had a dedicated law-enforcement presence focused on crimes that are often overlooked but can have lasting consequences for our communities and natural resources.

His work frequently took him far from the traditional duties associated with a deputy sheriff. He investigated illegal dumping sites, identified those responsible, coordinated cleanups, removed abandoned waste, and worked to protect the creeks, streams, and land that make up Osage County.

The scale of that work has been significant.

In a May 2025 article published by Osage News, McAlister reported that in less than a year he had handled 58 calls for service, obtained 14 arrest warrants, identified and cleaned 69 sites, and helped collect and dispose of approximately 160,000 pounds of solid waste.

His philosophy toward environmental enforcement could be summarized by one simple observation he shared in that article:

โ€œEverything ends up in the water.โ€

For McAlister, environmental enforcement has never simply been about cleaning up trash. It has been about protecting private and public property, holding offenders accountable, preserving our natural resources, and leaving Osage County better than he found it.

Over the years, Deputy McAlister has become an invaluable member of the Osage County Sheriffโ€™s Office and a tremendous resource for citizens, landowners, county officials, and other agencies.

His retirement marks the end of an important chapter, but the mission he helped build will continue.

Following McAlisterโ€™s retirement, Deputy Bob Nail will assume the part-time position of Osage County Environmental Deputy. Nail brings extensive experience to the assignment, including training and service as a State Fire Marshal, along with additional environmental and law-enforcement experience that will help him continue the work McAlister established.

We congratulate Deputy David McAlister on his retirement and thank him for more than 16 years of dedicated service to the Osage County Sheriffโ€™s Office and the citizens of Osage County.

Some careers leave behind statistics. Others leave behind something you can actually see.

For David McAlister, his legacy can be found in cleaner properties, restored dumping sites, protected waterways, and thousands upon thousands of pounds of waste that are no longer scattered across Osage County.

Congratulations on your retirement, Deputy McAlister. Thank you for your friendship, your dedication, and your many years of service to Osage County.

โ€” Sheriff Bart Perrier

September 11, 2001, is a day most of us will never forget. I know I never will.

That morning, I was attending a law enforcement training class in Shawnee, Oklahoma, when we were interrupted by the news that something horrific was happening in New York City.

Like so many Americans, my first thought was that it must have been a tragic accident. Then, minutes later, as we watched the events unfold live, the second plane struck the South Tower.

At that moment, we knew.

Our nation was under attack.

It is difficult today to remember how different the world was then. Social media didn't exist. Cell phones were mostly just phones. Internet access was limited, and information traveled nothing like it does today.

I remember calling my agency's dispatch center โ€” then, as now, the Osage County Sheriff's Office. I spoke with Dispatcher Jeanie Brown. Our conversation was brief, but I still remember the uncertainty and uneasiness of that moment.

In many ways, September 11, 2001, was the last day of innocence for a generation of Americans. We watched our country change before our eyes.

Three months later, I became a father. The events of September 11 reinforced something in me that has remained throughout my life: I wanted a better and safer world for my family, and I wanted to do my part to serve and protect the people around me.

Twenty-five years have now passed. Memories fade. Generations grow up with no personal recollection of that morning. And at times, it can seem that our nation has forgotten the unity, patriotism, sacrifice, and sense of purpose that followed one of the darkest days in American history.

But I will never forget.

I will never forget the 2,977 innocent lives taken.

I will never forget the firefighters, law enforcement officers, first responders, military personnel, and ordinary citizens who demonstrated extraordinary courage.

I will never forget the families whose lives were forever changed.

And I will never forget how Americans came together afterward โ€” not as Republicans or Democrats, not as people divided by our differences, but simply as Americans.

History must be remembered. Its lessons must be taught. And we must always strive to do better as a society and as a nation.

On this 25th anniversary of September 11, may God bless the victims, the heroes, their families, and all those whose lives were forever changed on that frozen day in history.

May God bless our first responders, our military, and the United States of America.
