Before a single word is spoken in court, the San Bernardino District Attorney's office has already spent a lot of time building its case. They gather evidence, interview witnesses, analyze physical material, and put together a theory of what happened and why. It is a methodical process. And it starts way earlier than most people think.
If you are facing a violent crime charge in San Bernardino, understanding how that process works is not just background information. It is, kind of, the whole foundation your defense is built on. Knowing what prosecutors are looking for and how they find it changes everything about how you respond.
Our professional criminal defense law firm has handled violent crime cases throughout San Bernardino, Fontana, Ontario, Rancho Cucamonga, and across Southern California for 18 years. That is not a small thing. That is nearly two decades of watching how these cases move and knowing exactly where the pressure points are.
Tammy Higgins spent 16 years as a San Bernardino County public defender before opening her private practice. She worked alongside the same prosecutors and in front of the same judges who may hear your case. She has tried more than 100 jury trials, including homicide cases, and that inside knowledge of how San Bernardino prosecutors approach evidence gathering translates directly into how we prepare your defense.
Early Evidence Prosecutors Gather After a Violent Crime
The hours immediately after a violent crime are when the most time-sensitive evidence is collected. Law enforcement photographs the scene, documents injuries, recovers any weapons or objects involved, and interviews witnesses while memories are freshest.
The initial police report sets the foundation for everything that follows. How the scene was documented, who was interviewed, and what was recorded matter for both the prosecution and the defense. Gaps in early documentation, inconsistencies in initial witness accounts, and incomplete crime scene records are all things we look for when reviewing discovery materials.
Witness Statements and How They Are Used
Witness testimony is one of the most powerful tools available to prosecutors in violent crime cases. In San Bernardino County, prosecutors take witness accounts seriously and build their theory of the case around the most credible version that supports the charges.
Witnesses can be cooperative victims, bystanders, family members, neighbors, or responding officers. Their initial statements are documented. If those statements change between the initial interview and trial, the prosecution may use the earlier version to challenge the witness's credibility, or the defense may use the change to undermine the prosecution's narrative.
What a witness says in the immediate aftermath of an incident often carries significant weight. We look carefully at the circumstances under which statements were given, whether witnesses were under stress at the time, and whether the questioning itself shaped the answers that came back.
Physical Evidence and Forensic Analysis
Physical evidence in violent crime cases includes weapons or objects used in the offense, blood or DNA samples, clothing with injury-consistent transfer material, and photographs documenting injuries and the scene.
The prosecution has this evidence analyzed by forensic specialists and presents it at trial through expert testimony. Challenging physical evidence can involve questioning the chain of custody, the methodology of the forensic analysis, or the conclusions the expert draws from the data they reviewed.
In serious assault and homicide cases, physical evidence often forms the backbone of the prosecution's case. Understanding what the evidence actually shows versus what the prosecution is claiming it shows is a core part of how we prepare every defense.
Surveillance Footage and Digital Evidence
San Bernardino and the surrounding cities have significant surveillance coverage through businesses, traffic cameras, and residential systems. In violent crime cases, the prosecution routinely subpoenas footage from nearby cameras covering the hours surrounding the alleged offense.
Digital evidence also includes phone records, text messages, social media activity, and location data. Prosecutors use this material to establish timelines, relationships between the parties, and prior communications relevant to motive or intent.
Defense attorneys examine the same material. Surveillance footage consistent with the defendant's account, messages that establish context the prosecution is choosing to omit, and location data that contradicts the prosecution's timeline are all things we pursue actively in discovery.
How the District Attorney Decides What to Charge
The charging decision is not automatic. After reviewing the investigation, the San Bernardino District Attorney's Office decides what offense to charge, at what level, and whether to include enhancement allegations.
These decisions are influenced by the strength of the evidence, the cooperation of witnesses, the seriousness of any injury, the defendant's prior record, and the public interest in prosecution. Understanding how these factors interact helps predict what the prosecution will prioritize and where the defense has room to push back.
Charge decisions can sometimes be influenced through early defense intervention. A well-documented self-defense argument presented before formal charges are filed, or early evidence of witness credibility problems, can affect what the prosecution ultimately decides to file.
What We Do with the Prosecution's Evidence
Building a defense in a violent crime case is not about hoping the prosecution gets things wrong. It is about examining every piece of evidence independently, identifying the weaknesses in the prosecution's narrative, and constructing an account of events that the evidence actually supports.
We review all discovery materials, retain independent expert analysis when the case warrants it, conduct our own witness interviews within legal limits, and prepare cross-examination that challenges the prosecution's evidence at every point the facts permit. We have handled the full range of violent crime cases in San Bernardino courts, from assault and battery charges to homicide defense. We also handle post-conviction relief for people whose past convictions may warrant review under AB 600 resentencing or the Racial Justice Act, because the work does not always end at the verdict.
