“The forensic examination performed by JDS Criminalistics on my case provided me with a strong defense against the State’s theory. Throughout the pendency of the case, Jim was always available to brainstorm issues and offer guidance and support on technical issues. After speaking with Jim about technical issues in my case, I always felt more prepared to address the issues head-on. Jim is also a supremely skillful expert on the witness stand. He remained calm and collected even when the DA asked him the hard questions. I have no doubt that the not guilty verdict I just received on a sexual assault was due in part to the guidance and insight that Jeff offered. I am looking forward to working with Jim again in the near future.”

“I have known Jim for well over a decade, and he was our “go-to” forensic expert when I was prosecuting homicides as District Attorney. Jim is the consummate professional, and his expertise in a wide variety of forensic fields is beyond question. It is truly remarkable to have a forensic expert of Jim’s experience and quality available to private practitioners and criminal defense attorneys. His breadth of knowledge and experience will match, if not surpass, any expert a government agency can produce. I highly recommend him.”

“Jim came highly recommended from a variety of attorneys, all of whom praised his expertise and professionalism. Jim assisted me in a difficult felony burglary case involving fingerprint and shoeprint evidence. He immediately dove into the assignment and provided me with critical insight into the case. His glowing recommendations should have told me what to expect but even then, I was incredibly impressed with his prompt response and the depth of knowledge in the field. Jim’s work was critical, absolutely critical, in getting the charges dismissed and my client exonerated. Thank you, Jim. Anyone lucky enough to work with Jim will find him to be at the top of his profession.”

“I found Jim in the week prior to trial in a case I had just taken on. I was totally stressed about the limited prep time, but after hiring Jim, that stress disappeared. He was able to look at piles of crime scene photos and produce an expert report for me with blood pattern analysis and witness statement analysis in less than 2 days. That report not only had exactly what I hoped in it, but Jim went above and beyond and offered me assistance in questioning him on the stand regarding his opinion and what evidentiary strengths to emphasize. He is a true team player and a real professional. Sadly, we never even got to go to trial. After the district attorney’s office looked at his report, they offered to dismiss. Incredible! I can’t wait for my next opportunity to hire Jim again.”

“I have known Jim for over 20 years. He is the consummate professional. His demeanor in front of a jury is as cool and controlled as it is on a grisly crime scene. No doubt that Jim is one of the top criminalists in the state.”

“Over the years I have dealt with Jim Saviano regarding many different cases. The one thing that stands out in my mind is the Absolute Precision that Jim works with. When Jim is presented with a case, he looks over the case and comes up with his expert opinion based solely on the evidence at hand. He is objective in his opinions and is not persuaded by what one wants him to say but tells it like it is, good or bad. I recommend JDS Criminalistics, LLC for every case that needs the expertise of knowledge. Jim works with the utmost professionalism that is needed in this field. He helps me ask the correct questions in very difficult cases. Jim has opened the eyes of attorneys and investigators as to what a case has to offer. Jim cares for the people he works with and knows of the importance of these cases to our clients. I find that he is above reproach with his experience and expert opinions and when he offers an opinion, I am confident he knows of what he speaks.”

“I have worked with Jim on several occasions and can say that he was my favorite expert to put on the stand. He is extremely knowledgeable about his subjects and presents them in such a fashion that juries trust what he says. I always referred to him as “the professor” because that’s how he comes across to juries.”

“The forensic examination performed by JDS Criminalistics in my case yielded key information which advanced the investigation and provided important leads. Not only was the report provided quickly and within budget constraints, it exceeded the quality of examinations performed by forensic offices with far more resources and time.”

Attorney at Law
“I am very grateful to Jim for his willingness to jump into a case on short notice and complete fantastic work. He was able to show the jury that a glove box was open, allowing us to further our self-defense case. Jim helped me to better understand the science behind his opinions. He worked with us to make sure the truth was heard. I look forward to our next case.”

“Jim came highly recommended as a forensic photographer for a breach of residential lease civil case that I tried. His photos showed the difference between normal light, in which the extensive dog urine contamination was invisible, and ultraviolet light, which showed it very graphically. His photos were spectacularly effective, and very professionally done. He made a real difference in our case, and we were awarded everything we asked for. I highly recommend Jim for his professionalism and effectiveness.”
– Rick Calloway
Attorney at Law
“Jim and I worked a cadaver search for buried bodies recently, and I was able to see him apply his skills in the field. He approaches a crime scene circumspectly, and gives a lot of thought to how and when he applies his technical knowledge. He is affable and pleasant to work with, and contributed a great deal to our search team’s efforts.”

“I had the opportunity to work with Jim several times while I was a deputy district attorney. His knowledge of crime scene investigation and reconstruction. He is a consummate professional and an educator at heart. He also has a unique ability to connect with a jury, explaining complex issues in an engaging way that really strikes a chord with them. Jim is an expert you can count on to do a thorough job and back it up in court. Now, as a defense attorney, I would highly recommend him.”

“No one in the DFW private investigation business has the ability to do the things Jim brings to the table. A well rounded criminalist is as difficult to find as the location of Jimmy Hoffa’s body — hey, bet Jim can find it!”
