Killeen, Texas – A Killeen man is facing multiple felony charges after authorities say he repeatedly targeted the same convenience store in a short span of time. Investigators allege the suspect carried out three armed robberies at one location, escalating concerns about repeat offenses and public safety in the area.
A Bell County grand jury this week formally indicted 29-year-old Mark Anthony Santiago on three counts of aggravated robbery, each classified as a first-degree felony. The charges stem from a series of incidents that police say occurred over less than two weeks at the same business.
Incident Overview
According to investigators, all three robberies took place at the Texan Mart convenience store located in the 3000 block of Lake Road in Killeen. Police allege the suspect returned to the same store multiple times, using force or the threat of force during each incident.
Aggravated robbery is among the most serious criminal charges under Texas law and typically involves the use of a weapon or actions that place victims in fear of serious bodily harm. In this case, authorities believe the repeated nature of the crimes added to the severity of the situation.
Timeline of Events
Court documents outline a clear pattern in the alleged offenses. The first robbery reportedly occurred on October 26, 2025. Just four days later, on October 30, 2025, investigators say the same suspect returned to the same store and committed another robbery.
Less than ten days after that, a third incident was reported on November 7, 2025, again at the Texan Mart on Lake Road. All three incidents were detailed in an arrest affidavit prepared by law enforcement.
Police believe the close timing and consistent location helped investigators identify a suspect and build a case that ultimately led to the grand jury indictment.
Details From Police and Court Records
According to the Killeen Police Department, surveillance footage, witness statements, and investigative follow-up played a role in connecting the suspect to all three incidents. The arrest affidavit submitted to the court outlines similarities in the alleged robberies, including the location and method used.
A Bell County grand jury reviewed the evidence and returned indictments on Wednesday, formally charging Mark Anthony Santiago with three first-degree felony counts. If convicted, each charge carries the possibility of a lengthy prison sentence under Texas law.

Additional Context on Repeat Robberies
Criminal justice experts note that repeat offenses at the same location are not common but do occur when suspects believe a business is vulnerable. Convenience stores are often targeted because they handle cash, operate late hours, and may have limited staffing.
Law enforcement agencies typically advise store owners to review security practices following even a single incident. Multiple robberies at the same business can place employees and customers at heightened risk, both physically and emotionally.
Safety and Crime Prevention Awareness
Police continue to encourage local businesses to invest in visible security measures such as high-resolution cameras, improved lighting, and clear sightlines inside stores. Employees are also urged to prioritize personal safety and comply with suspects during robberies, as property can be replaced but lives cannot.
Community members are reminded to report suspicious activity and cooperate with investigators when incidents occur. Timely information from witnesses often plays a crucial role in identifying suspects and preventing further crimes.
Conclusion
The indictment of Mark Anthony Santiago marks a significant step in a case that raised alarms due to the repeated targeting of the same Killeen convenience store. As the case moves through the court system, authorities emphasize the importance of vigilance, reporting, and preventive measures to reduce the risk of similar incidents in the future.
