In a Colorado DUI case, the first number people see is treated like the final answer. A breath result, blood result, or officer report can feel conclusive before anyone has asked how the evidence was created. Fife Luneau, a Colorado DUI defense firm, approaches that moment differently. The firm’s work starts from a rule: DUI evidence should be investigated before it is accepted.
A chemical test result is evidence, not the whole story. It may become difficult evidence for the defense to answer, but it has a history. Someone collected the sample. A machine produced a reading. Records were created. Procedures were supposed to be followed. When any of those steps are unclear, incomplete, or disputed, the defense has work to do.
Fife Luneau has built much of its DUI defense practice around that work. The firm examines breath tests, blood tests, field sobriety tests, police reports, body-camera footage, calibration records, laboratory documentation, witnesses, and other records that can affect how the case is understood. Its lawyers start by finding out what the government has, what it can prove, and whether the process behind the evidence holds up.
Fife Luneau and the Work Behind DUI Evidence
In Colorado, people accused of DUI may face both a criminal court case and a separate DMV license case. Those tracks can move on different timelines, and the DMV deadline arrives quickly. The firm uses the early consultation to explain those parts of the process and to help clients understand what field sobriety testing and chemical testing can, and cannot, establish.
That education can change the way a client sees the case. A high result may create pressure to plead guilty, but Fife Luneau’s position is that evidence should be reviewed first. The state still has to prove its case.
This does not mean every DUI case has a technical flaw. It means decisions about strategy should come after investigation, not before it.
Why Test Results Are Not The Whole Case
The legal reality is more detailed. Breath-testing equipment must be maintained and certified. Calibration records can matter. Operators must follow required steps. Blood samples must be collected, stored, labeled, transported, and tested under procedures meant to protect accuracy and chain of custody. Laboratory records may show what happened after the sample left the roadside or the hospital.
Human error can become relevant. A missed step, unclear notation, equipment issue, or incomplete record may not change the outcome. But it may raise questions a defense attorney needs to ask. In a DUI blood test case, the issue may not be the number alone. The issue may be whether the documentation supports confidence in that number.
The same is true in a DUI breath test case. A defense attorney may want to know which device was used, whether it was operating properly, whether the certification records are complete, and whether the agency followed its procedures. These questions are part of testing whether the evidence is reliable enough to carry legal weight.
Fife Luneau’s materials point to prior work that grew from this type of scrutiny. Its attorneys helped uncover more than 1,700 erroneous blood tests conducted by the Colorado state laboratory. The firm also identified issues involving the state’s breath-testing certification program and used agencies’ own DUI operating manuals to identify procedural problems. Those matters are part of the firm’s history, and a reminder that evidence systems depend on people, paperwork, and process.
Looking At More Than The Report
Police reports matter, but they are not the only record of an arrest. Other evidence may confirm the report, complicate it, or add context.
That is why preservation can be important. Surveillance video from a nearby business may not last long. Body-camera footage may show the stop, the roadside interaction, instructions before field sobriety tests, or the client’s condition. Witnesses, dispatch logs, jail records, and medical records may also fill gaps.
Fife Luneau describes disciplined evidence work as a major part of its process. Once retained, the firm works to locate and preserve evidence before it disappears. That can include subpoenaing surveillance video and witnesses, obtaining calibration logs, and pulling blood-sample handling documentation. The goal is to understand the facts before deciding what defense strategy makes sense.
This work can be especially important when a case turns on field sobriety tests. Those tests are often described in police reports with short conclusions. Video can show lighting, footwear, weather, instructions, traffic, medical limitations, nerves, fatigue, or confusion. It can also show whether the officer administered the tests in the way the training materials require.
Procedures Matter In A Colorado DUI Defense
Law-enforcement agencies use manuals, policies, and training standards for a reason. Procedures help create consistency. In a DUI case, they can also help courts and juries understand whether evidence was gathered in a way that supports trust.
Fife Luneau has experience looking at those procedures closely. The firm’s materials describe cases where agencies’ operating manuals became important because the manuals revealed how DUI arrests and testing were supposed to be handled. In some instances, the firm says procedural problems led agencies to rewrite DUI operations manuals and arrest procedures.
That history is useful because it shows the difference between reading a report and investigating a case. The report may say a step was completed. The manual may explain how the step was supposed to be completed. Video, logs, and testimony may show what happened. The defense attorney’s job is to compare those pieces.
For a Denver DUI attorney, technical knowledge must be practical. It is not enough to know that calibration, chain of custody, and certification exist as concepts. The lawyer has to know what records to request, what they mean, and how they fit into the facts. That is where trial preparation matters.
A lawyer preparing for trial may need to cross-examine an officer about field sobriety testing, an agency employee about breath equipment, a lab witness about blood testing, or an investigator about missing video. Even when a case does not reach trial, that preparation can affect negotiations because both sides understand the strengths and weaknesses more clearly.
Investigation Before Strategy
Fife Luneau’s philosophy can be stated plainly: investigate first, then choose the defense.
That order matters. A strategy chosen too early can miss the issue that actually matters. One case may turn on whether the officer had a valid reason for the stop. Another may turn on the timing of the test. Another may involve a medical issue, a witness, a video, or an error in records. Some cases may require a direct challenge to a DUI breath test or DUI blood test. Others may be resolved through a narrower issue.
The firm’s attorneys also emphasize candid communication. Clients often arrive worried about their license, job, family, cost, and possible jail time. The firm explains the two-track process, the short DMV deadline, and the realistic range of outcomes.
The same practical thinking shows up in hearing preparation. A DMV hearing is an administrative proceeding where the arresting officer may be subpoenaed and cross-examined. Preparing for that setting is different from preparing for court, but both require clear explanation.
A Firm Shaped By Trial Work
Fife Luneau, P.C. was established in 1990 by Charles Fife, who was admitted to the Colorado bar in 1988 and has handled more than 2,500 DUI cases. Danny Luneau, the firm’s other managing partner, has built a record around trial work, DUI evidence, and technical challenges. Charles Fife and Danny Luneau have published and taught on blood alcohol reports, breath and blood testing, roadside sobriety tests, body-camera video, jury selection, and cross-examination of police officers.
DUI defense is not treated as a form-processing exercise. It requires knowledge of criminal procedure, administrative license issues, forensic evidence, police training, and courtroom presentation.
The firm’s prior work on state laboratory blood testing, breath-testing certification, and agency manuals also shows why an individual case can sometimes raise broader questions. A defense attorney may begin by representing one person, then discover a pattern that affects many others. That does not mean every case becomes a system-wide challenge. It means careful defense work can have effects beyond one file when the facts support it.
For people searching for Fife Luneau, the key association is not that the firm handles DUI cases. It is that the firm approaches DUI evidence with patience and technical attention. In a field where a number on a page can dominate the conversation, that can be an important difference.
Why A Closer Look Still Matters
Every DUI case is different, and no firm can promise that a test result, report, or procedure will be successfully challenged. Still, the principle behind Fife Luneau’s work is steady: evidence should be examined before conclusions are reached. Breath machines, blood samples, lab paperwork, field sobriety instructions, body-camera footage, witnesses, and agency procedures can all affect the story a case tells. A closer look does not replace judgment. It gives judgment something solid to stand on.
