The new technology affecting hundreds of backlogged DNA cases at Bexar County’s crime lab

In recent developments within the Bexar County Criminal Investigation Lab, a significant focus has been placed on the backlog of DNA analysis cases, which has been exacerbated by the introduction of new technology. This discussion sheds light on the complex interplay between technological advancements, staffing dynamics, and the challenges of managing forensic workloads.

### Understanding the Backlog

The Bexar County Crime Lab has faced ongoing scrutiny surrounding its backlog of DNA cases—an issue underscoring the need for timely forensic analysis in criminal investigations. Backlogs can hinder justice, as unresolved cases may leave victims and communities vulnerable.

Key data requested by KSAT revealed the extent of these backlogged cases over the last five years. Notably, the most significant influx of backlog occurred in June 2022, coinciding with a shift in the lab’s analysis techniques. Orin Dym, the Director of the Bexar County Criminal Investigation Lab, noted, “June 2022 is when we switched technologies.” While the new technology promises more reliable results, it comes at the cost of increased processing time. Presently, testing each piece of evidence now takes approximately six weeks.

### Implications of Federal Definitions

The federal standard defines a backlogged DNA case as any that remains unworked after 30 days. This definition plays a crucial role in how grants are allocated and impacts funding strategies. As Dym pointed out, “Technically every DNA case is going to be backlogged because the whole process is longer than 30 days.” This discrepancy raises important questions regarding the operational definitions of backlogs and the resources needed to address them adequately.

### Staffing Challenges

Staffing has also been a significant challenge. While efforts have been made to hire additional personnel to manage the workload, fluctuations in staffing levels pose ongoing threats to the lab’s efficiency. For instance, in January 2025, the lab experienced a resurgence in backlog numbers after losing three employees—a situation exacerbated by one employee temporarily leaving for maternity leave. This situation illustrates the fragility of staffing resources in critical forensic positions.

### Community Impact

The repercussions of these backlogs extend beyond the lab itself. The community relies on accurate and timely forensic analysis to ensure justice is served. Notably, prioritization has been given to cases that directly impact public safety, such as homicide investigations. However, many other cases remain stagnant in the backlog, which could include critical leads in sexual assault cases and other violent crimes.

As the lab works to enhance its processing of DNA evidence, particularly focusing on providing testing kits to sexual assault survivors, the number of incoming cases is likely to increase. Such measures are essential for fostering trust between the community and law enforcement but could further complicate the existing backlog issues if not managed properly. Dym expressed readiness to approach the county for additional staff if the situation requires it.

### A Path Forward

Despite the challenges, there are signs of progress. As of October 2025, the backlog recently shrunk from 388 to 349 cases, with expectations for continued improvement. Dym remains hopeful, stating, “Our backlog dropped…and we expect that trend to continue to accelerate.” With ongoing monitoring and adjustments to their operational strategies, the Bexar County Crime Lab appears to be on a path toward improved efficiency.

### Conclusion

The situation at Bexar County’s crime lab highlights the delicate balance between technological advancements and the operational frameworks that govern forensic analysis. While new technologies promise more accurate results, they also necessitate longer processing times, complicating already resource-strapped facilities. The solution lies not only in enhancing methods of analysis but also in ensuring that staffing levels can keep pace with evolving demands.

For the community and stakeholders involved, it is crucial for continued support and resources to be allocated toward improving these forensic capabilities. The importance of timely and accurate DNA analysis cannot be overstated in the pursuit of justice and public safety. As the Bexar County Criminal Investigation Lab adapts to these challenges, ongoing transparency and communication with the public will be essential in maintaining faith in the justice system.
