Deputy Fired: What’s Next in the John Mendoza Jr. Shooting Investigation?
The firing of former Brazoria County Deputy Kevin Tippit has answered one question in the shooting death of 18-year-old John Gabriel Mendoza Jr., but many others remain.
Sheriff Bo Stallman announced June 9 that Tippit was terminated following an internal review that found policy violations related to the handling and discharge of his firearm. The decision came just days after the June 1 shooting that left Mendoza dead in Lake Jackson.
While Tippit’s employment with the sheriff’s office has ended, the criminal investigation is far from over.
Why Was Deputy Kevin Tippit Fired?

According to Sheriff Stallman, Tippit was fired after an internal review found violations of department policy involving the handling and discharge of his firearm.
The sheriff emphasized that the termination was an administrative decision and separate from the ongoing criminal investigation.
The firing does not determine whether any criminal charges will be filed. That decision will be made through the criminal justice process after investigators complete their work.
What Happened to John Mendoza Jr.?

Authorities say the incident began shortly after midnight on June 1 when a Brazoria County Sheriff’s Office deputy attempted to stop a vehicle near FM 2004 and This Way Street in Lake Jackson.
The encounter ended in the 100 block of Indian Warrior Trail, where John Gabriel Mendoza Jr., an 18-year-old Texas State University student, suffered a gunshot wound and later died.
The Texas Rangers were called in to conduct an independent investigation into the shooting.
What Are the Texas Rangers Investigating?
The Texas Rangers are responsible for reviewing all evidence connected to the shooting.
Their investigation is expected to include:
Body camera footage
Radio traffic
Witness statements
Physical evidence
Firearm evidence
Forensic testing
Autopsy results
Investigators will work to determine exactly what happened and whether any criminal laws were violated.
Once the investigation is complete, the findings will be submitted to prosecutors for review.
The Case Will Go Before a Grand Jury
Brazoria County Criminal District Attorney Tom Selleck has already confirmed the completed investigation will be presented to a grand jury.
A grand jury reviews evidence presented by prosecutors and determines whether criminal charges should be filed.
Grand jurors do not decide guilt or innocence. Instead, they decide whether sufficient evidence exists to move the case forward.
Possible outcomes include:
No criminal charges
Criminal charges filed
Requests for additional investigation
Grand jury proceedings are conducted in secret under Texas law.
How Long Could the Investigation Take?
Officials have not provided a timeline for when the investigation will be completed.
However, District Attorney Tom Selleck has indicated that forensic testing and other investigative steps could take several months.
Complex officer-involved shooting investigations often require extensive evidence review before prosecutors are prepared to present a case to a grand jury.
What Happens Next?
With Deputy Kevin Tippit no longer employed by the Brazoria County Sheriff’s Office, attention now turns to the criminal investigation.
The Texas Rangers continue gathering evidence and reviewing the circumstances surrounding the shooting death of John Mendoza Jr.
Once that process is complete, prosecutors will present the findings to a grand jury, which will determine whether criminal charges are warranted.
Until then, Mendoza’s family, investigators, and the community continue waiting for answers.
Conclusion
The firing of former Deputy Kevin Tippit marks a significant development in the John Mendoza Jr. shooting investigation, but it is not the final chapter.
The Texas Rangers investigation remains active, and the case is expected to be presented to a grand jury once investigators complete their review.
