HUMBLE, Texas – In December, 2 Investigates was the first to report on problems within the City of Humble’s Police Department.
Since our initial report on an employee survey critical of department leadership, Police Chief Dan Zientek has been placed on administrative leave with pay. That status was later changed to administrative leave without pay.

Leadership within the City of Humble and its police department has declined to speak with 2 Investigates on camera, citing an ongoing investigation being conducted by an outside law firm.
Outside police headquarters Monday, we did find one long-time resident willing to speak out.
“I am concerned because I do feel vulnerable,” said Kathy, responding to what she has learned about problems inside the police department—including nearly 30 officers who have left over the last three years.
While 2 Investigates was at Humble PD attempting to speak with the interim chief, Kathy was also there, hoping to talk with an officer about crime close to home.
“There was graffiti on the street at the end of my street,” she said.
Days after Zientek was placed on administrative leave, 2 Investigates revealed he was listed as part of a private company’s executive leadership team. The company, Acquire Training Solutions, specializes in law enforcement training and advertised past courses offered at Humble Police Headquarters for a fee.
Since our last update on Dec. 23—which focused on the employee survey provided by the city—we have obtained additional information involving travel and training expenses within the department.
Kathy said she was surprised to learn that nearly $40,000 in expenses were charged over the last two years by the former chief’s wife, Twyla Kimberlin.
Kimberlin, who was promoted twice—from sergeant to captain—over a four-month period last year, accumulated expenses that exceeded Chief Zientek’s by roughly $20,000 during fiscal years 2024 and 2025.
“We found those numbers to be alarming,” the city manager said to 2 Investigates, who added, “We are examining all irregularities” tied to the expenditures.

According to the city, the individual with the fifth-highest expenses—nearly $15,000 over the last two years—is Kevin Wolf.
Public records provided to 2 Investigates include a Nov. 2022 letter from Humble PD informing Wolf that he had failed his background investigation and that the department could no longer “continue the application process.”
Despite that, Wolf was later hired.
The city manager stated those concerns were “fully and satisfactorily explained by the department” and that the city is “not inclined to reverse that hiring decision at this time.”
City officials say the overall investigation into Zientek and his leadership is being handled methodically to ensure accuracy and completeness.
