The Bell County Sheriff's Department operates the Bell County Jail in Belton, the county seat. The facility processes bookings from the sheriff's department, Killeen Police Department, Temple Police Department, Belton Police Department, and other municipal agencies throughout the county. Booking records, including photographs, charges, and bond information, are publicly accessible under the Texas Public Information Act (Tex. Gov’t Code Ch. 552). The Bell County online jail roster provides searchable inmate information that is updated as bookings are processed.

Fort Cavazos—renamed from Fort Hood in 2023 as part of the U.S. Army's renaming of installations commemorating Confederate officers—is the dominant institution in Bell County. The post covers approximately 214,000 acres and is home to III Armored Corps, the 1st Cavalry Division, and the 3rd Cavalry Regiment, among other units. The active-duty military population and their dependents significantly influence Bell County's demographics, economy, and law enforcement workload. Killeen, the largest city in the county with a population exceeding 160,000, developed almost entirely as a military support community adjacent to the post.

About Bell County

Bell County sits at the intersection of Interstate 35 and U.S. Highway 190 in central Texas, roughly midway between Austin and Waco. Temple, the county's second-largest city, is a regional medical hub anchored by Baylor Scott & White Medical Center, one of the largest healthcare systems in Texas. Belton, the county seat, is a smaller community known for the University of Mary Hardin-Baylor and its historic courthouse square. Harker Heights and Copperas Cove round out the county's principal communities, both closely tied to the military economy of Fort Cavazos. The county's population has grown steadily, driven by military expansion and the broader growth of central Texas along the I-35 corridor.
