Hill is accused of stealing more than $100,000 from the Harris County Deputies Organization. She fled town before the indictment was handed down.
Eyewitness News reporter Jeff Ehling was the only local reporter at the airport when Hill surrendered.
Hill said nothing as she walked down to baggage claim here in terminal B and surrendered to a waiting deputy.
Hill refused to answer any questions and was led away without saying a word.
Hill was once the union's office manager.
Court documents allege that Hill stole money between 2012 and 2014. She is the widow of Deputy Barrett Hill who died in the line of duty in December 2000.
In a statement, the Deputies Union discussed the firing of Hill saying, "In May of 2014 irregular financial activity was detected. The irregular activity led to the termination of the organization's then-office manager in early May of 2014."
That information was turned over to the Harris County District Attorney's Office which returned an indictment.
After being fired, Hill apparently moved out of town.
Hill flew in from Richmond, Virginia and is on her way to the Sheriff's office now.
