Investigators


Before they worked for the defense, they built the files the State relies on. Deputy Chief, Captain, Lieutenant, Homicide Sergeant, Crime Scene and Federal Task Force officers, plus fire investigation and open source intelligence.

Senior Investigator

Skeeter Anderson

Ask around the Tarrant County courthouse and the lawyers already know Skeeter Anderson: 32 years with the Fort Worth Police Department, and more than two decades since as a licensed private investigator in Tarrant and surrounding counties.

Full background

Skeeter retired from Fort Worth PD at the rank of sergeant in 2002. While serving Fort Worth, he gained experience across a wide range of assignments. He worked patrol throughout the city for approximately five years, then began a series of investigative and supervisory assignments. His investigative experience includes homicides and other major cases, child abuse cases, thefts, and white collar crimes. As a supervisor, he served in patrol, the Theft Unit, the Commercial Auto Theft Unit, the Family Violence/Sexual Assault and Crimes Against Children Unit, the School Initiative Unit, and the Homicide Unit, where he also served as acting lieutenant for the Violent Personal Crimes Unit. Along the way, Skeeter was named Fort Worth Police Department Officer of the Year for 1979 and received a Certificate of Merit for one of his white collar investigations.

Skeeter also worked in an undercover capacity and helped establish the Children's Advocacy Center. Away from work, Skeeter is an active member of Pantego Bible Church and a long-time class administrator for Bible Study Fellowship.

Senior Investigator

Pat Blauser

If your case is buried in financial records, Pat Blauser spent thirty years building cases from paper just like it, on the other side. He led multi-agency fraud investigations to state and federal convictions and reads a balance sheet as fluently as a case file.

Full background

An early adopter of OSINT tools and methodologies long before they became standard, Pat pursued advanced training beyond core detective programs, including the Reid Technique, Force Science, and i2 Analyst Notebook. He served as an academy instructor for fraud investigations, and investigated violent personal crimes throughout much of his law enforcement career.

He holds a Bachelor of Business in Real Estate from the University of North Texas. As Treasurer of his police union, he resolved internal financial malpractice, implemented new financial controls, aided in the recovery of lost funds from fraud, and supported an SEC investigation in which the union was a victim. Pat also brings more than 20 years of combined experience as a licensed real estate broker and appraiser, including directing the acquisition, renovation, and leasing of the union headquarters building in downtown Fort Worth, adding deep expertise in due diligence, financial analysis, and asset valuation to his investigative work.

Investigator

Robbie Fenyes

If your defense depends on a paper trail — shipping records, compliance files, business documentation — Robbie Fenyes spent 25 years building and defending exactly that under federal scrutiny at FedEx, DHL, and Expeditors International.

Full background

Robbie is a Licensed Texas Private Investigator with Third Chair Investigations LLC, supporting criminal defense attorneys across Texas through witness interviews, alibi development, evidence review, timeline reconstruction, and trial preparation. His executive career in import/export compliance and operations centered on documentation, verification, and defending a record under scrutiny — the same discipline that drives a defensible investigation.

He launched the Cleburne Railroaders as President and General Manager, generating over $1.225M in first-year revenue, and is Managing Partner of Lonestar Baseball DFW. Robbie develops facts objectively, protects confidentiality, and gives attorneys investigative work they can put in front of a jury.

Senior Investigator

Fred Gilbert

If your case comes down to what a witness will actually say, Fred Gilbert has spent thirty years getting people to talk. FBI- and Reid-trained in interviewing and deception recognition, he retired as a Fort Worth Police Lieutenant after a career running from patrol to narcotics to crimes against children.

Full background

Beginning his career as a Patrol and Bicycle Officer, Fred steadily advanced through the ranks, serving as a Corporal assigned to Patrol and the Crimes Against Children Unit, a Sergeant supervising Patrol and Narcotics investigations, and ultimately as a Lieutenant, where he spent 17 years leading patrol operations, supervising personnel, and overseeing complex investigations.

Fred has received advanced investigative training from the FBI and the Reid organization in criminal investigations, narcotics investigations, deception recognition, interview and interrogation techniques, and investigative interviewing. His ability to quickly establish rapport, recognize deception, and obtain critical information has consistently produced exceptional investigative results throughout his career.

Widely respected for his professionalism, leadership, and commitment to justice, Fred was awarded the Medal of Valor and was honored as Officer of the Year by both the Fort Worth Rotary Club and the Fort Worth VFW. He was also nominated on three separate occasions for Supervisor of the Year, reflecting the confidence and respect he earned from both his peers and department leadership.

Fred's investigative strengths include witness interviews, statement analysis, interrogation, evidence review, case reconstruction, and identifying investigative inconsistencies that can significantly impact the outcome of a criminal case. His exceptional communication skills allow him to build trust with people from every background, often obtaining information others cannot.

As a Senior Investigator with Third Chair Investigations LLC, Fred applies decades of law enforcement leadership and investigative experience to provide thorough, objective, and defense-focused investigations. He works closely with defense counsel to uncover facts, identify overlooked evidence, develop witnesses, and ensure every case receives a comprehensive and independent review.

Outside of his investigative work, Fred is a Black Belt in both Judo and Brazilian Jiu-Jitsu, enjoys playing ice hockey and fishing, and treasures spending time with his family, especially his grandchildren.

Senior Investigator

Pat Henz

If the file the State handed you came out of a major-case unit, Pat Henz spent his career inside one, working the critical incidents referred straight from the Chief of Police's desk.

Full background

Pat spent 30 years with the Fort Worth Police Department before retiring in 2018 and joining Third Chair Investigations. He finished his career in the Major Case Unit, where he handled officer-involved shootings, in-custody deaths, kidnappings, and murder-for-hire. From 2016 until his retirement, he also served as a Federal Task Force Officer with Homeland Security and U.S. Customs and Border Protection, investigating human trafficking.

Before Major Case, Pat worked Crimes Against Children for four years and spent a decade in the Crime Scene Search Unit. He holds a TCOLE Master Peace Officer License and a B.S. in Criminal Justice from UT Arlington. He has trained other officers and investigators throughout his career, including crime scene courses, child abuse investigations, and missing and exploited children cases at the Fort Worth Police Academy.

Senior Investigator

Bryan Jamison

If your case involves an officer-involved shooting, a crime scene the State calls conclusive, or a fire someone has already labeled, Bryan Jamison has worked the other side of all three.

Full background

He retired from the Fort Worth Police Department as a Captain in 2023 after 31 years. As a Major Case detective he was the primary investigator on 25 officer-involved shootings and assisted on dozens more, so he knows how those files get built and what gets left out of them. He supervised the Crime Scene Search Unit, rewrote its training and standard operating procedures, and in the Fraud unit wrote the grant that stood up the department's first digital forensics detective position, putting him on video and electronic evidence years before most agencies caught up.

Bryan is a graduate of the FBI National Academy (Session #264, 2016), the Bureau's invitation-only program at Quantico for senior law enforcement leaders. Candidates are nominated, not enrolled; each 10-week session takes roughly 250 officers drawn from every state and more than 160 countries, and the coursework runs through law, forensic science, and behavioral science. The alumni association counts its graduates among the top 1% of law enforcement leadership worldwide. He also holds a Master of Criminal Justice from Tarleton State University and an FBI National Academy instructor background in incident management.

His fire experience comes from the fire service, not a police arson desk. He's a Master Fire Investigator and Master Certified Firefighter through the Texas Commission on Fire Protection, a licensed paramedic since 1996, and has been Fire Chief of the Briaroaks Volunteer Fire Department for more than 30 years. When a fire's cause and origin are in dispute, he can read the scene and the report.

Senior Investigator

Sharon Kamper

When a case turns on how a police department actually operates, Sharon Kamper ran one. She retired as Deputy Chief of Operational Command at the Fort Worth Police Department after 31 years of service, 23 of them in leadership.

Full background

Throughout her career, Sharon led major investigative, patrol, training, and administrative divisions while earning a reputation for integrity, strategic leadership, and a commitment to public service. A graduate of the FBI National Academy and the Southern Police Institute, she holds degrees in Criminal Justice and completed graduate studies in justice administration. She is the recipient of numerous commendations, including the Emma Richardson Award for Excellence in Female Law Enforcement Leadership, and remains passionate about mentoring leaders, serving her community, and advancing professional excellence.

Investigator

Heather Nering

If your case turns on a phone extraction or ten thousand pages of bank records, Heather Nering has spent her career on both. Twelve years handling every piece of digital evidence that moved through a Texas DA's office, and fifteen before that inside banking and the family business ledgers.

Full background

Heather spent more than twelve years at the McLennan County District Attorney's Office as Discovery Coordinator, where every piece of digital and physical evidence flowing in from law enforcement crossed her desk. She managed discovery compliance under the Michael Morton Act, analyzed cellphone extractions using Cellebrite, prepared case files for Grand Jury review, and trained prosecutors, staff, and outside agencies on eDiscovery systems and Cellebrite software. She also maintained and corrected CJIS records and worked directly with law enforcement units, including gang units, to support case development. Few people on either side of the docket have handled the volume of digital evidence she has.

Since 2019, Heather has worked criminal cases from the defense side with the Law Office of Gill & Brissette, managing an active caseload of more than 100 misdemeanor and felony matters. Her work includes analyzing police reports and evidence for inconsistencies, drafting motions and subpoenas, coordinating witnesses, and providing full trial support.

Her strength in financial cases predates her legal career. She spent a decade and a half in banking and business finance, rising from teller to operations manager with auditing responsibilities, and before that learned accounting keeping the books at Martin Tool and Supply, her family's business, in operation since 1974. When a case turns on thousands of pages of bank records, she reads them from the inside. She knows how the transactions were built, how banks audit them, and where the paper trail thins out.

Investigator

Brian Nickelson

If your case turns on a criminal history record or on what happens inside a Tarrant County courtroom, Brian Nickelson spent 31 years on the inside of both.

Full background

Born and raised in Fort Worth, Brian began his career with the Tarrant County Sheriff's Office in the Booking Division in 1993. There he played an instrumental role in implementing the Criminal History Reporting Form, a new statewide process introduced that year for documenting criminal charges. Because every agency in Tarrant County was required to submit these forms, each one passed through Brian's desk before being forwarded to the Texas Department of Public Safety, giving him extensive experience with criminal history reporting and records management.

After approximately eight years in Booking and earning his Texas Peace Officer License, Brian transferred to the Judicial Division. He served as a bailiff in the Family Law Courts for approximately six years before being assigned to the 396th District Court in 2009, where he remained until his retirement, completing more than 31 years of service with the Tarrant County Sheriff's Office.

In the District Court, Brian was entrusted with numerous high-profile criminal trials, including multiple death penalty cases that attracted significant media attention and heightened security concerns. He developed extensive expertise in courtroom security, jury management, and judicial operations, along with a working knowledge of jail operations, court procedures, and the coordination required to support complex trials.

That background pays off twice for defense attorneys: Brian knows how a criminal history record gets created, reported, and corrected, and he knows how a courtroom actually runs when the stakes are highest.

Certified OSIP Investigator

Lindsay Nordstrom

If the answer exists somewhere online, Lindsay can find it and document it so it survives an authentication challenge. She is an IntelTechniques Certified Open Source Intelligence Professional with a litigation paralegal's grounding in evidentiary standards.

Full background

Specializing in legal investigations, Lindsay combines advanced OSINT methodologies with a strong understanding of evidentiary standards and the authentication of digital evidence. Drawing on her background in the legal field, she delivers clear, well-documented intelligence findings that support attorneys, private investigators, and litigation teams. Her analytical approach, attention to detail, and commitment to accuracy have established her as a trusted resource in the OSINT profession.

Before transitioning into intelligence work, Lindsay built a career as a litigation paralegal, focusing on legal research, case development, and trial preparation. She holds an Associate Degree in Paralegal Studies and served for five years as a Court Appointed Special Advocate (CASA), advocating for abused and neglected children within the judicial system.

Lindsay completed advanced OSINT training and earned the OSIP certification through IntelTechniques, a leading provider of open source intelligence training and methodology. Her combination of OSINT expertise, legal experience, and understanding of evidentiary requirements makes her a valuable asset in complex investigations and litigation support matters.

Fire & Explosives Investigator

Ronny Schultz

If your case involves fire, arson, or explosives, Ronny Schultz spent 30 years investigating exactly that as a command officer and fire investigator, trained by the FBI and federal hazmat teams on post-blast analysis and catastrophic incident response.

Full background

Ronny is a Certified Fire Investigator through the International Association of Arson Investigators (IAAI-CFI), holding a Master Peace Officer license and Texas Private Investigator credentials. He retired from the City of Fort Worth Fire-Rescue, where he served as an Arson and Bomb Investigator, gaining on-the-ground experience with crime scene investigation, evidence handling, and how fire scenes transition from emergency response to criminal investigation. He then moved into fire service leadership, serving as Assistant Fire Marshal in Parker County, Fire Chief and Head of Department for Parker County ESD #3, and Assistant Chief/Fire Marshal with Sansom Park Fire-Rescue — roles that required him to oversee investigations, certify findings, and prepare evidence for prosecution.

His federal training gives him perspective most investigators don't have. Ronny holds FBI certifications in Hazardous Device Technician work and Post-Blast Investigation, Department of Justice credentials in WMD and Terrorist Bombings response, and training through the Homeland Security radiological and nuclear response programs. For more than twenty years, he served with Texas Task Force 1 USAR, a federally and state-funded search and rescue team, gaining extensive hands-on training in hazardous materials, CBRN response, and multi-agency coordination in catastrophic incidents. He graduated from the National Fire Academy and the Texas Fire Chiefs Academy, holding additional certifications as a Master Fire Investigator, Master Fire Instructor, HazMat Technician, and Incident Safety Officer through the Texas Commission on Fire Protection.

What this combination means for your case: Ronny understands how fire and arson scenes are documented, what methodology investigations follow, where standards are applied correctly and where they aren't, and how evidence gets presented in the courtroom. He reads those reports from the prosecution perspective and the investigative methodology perspective. When a fire's cause and origin are in dispute, or when the allegation hinges on forensic evidence at a scene, he can identify weaknesses in the investigation, the evidence chain, and the expert conclusions.
