Introtech News Room

On September 5, 2025, Vincent Cronin and Matthew Healy were featured speakers at the Ohio Identification Officer’s Association (OIOA) Annual Conference held in Dublin, Ohio.

Mr. Healy delivered an in-depth, two-hour presentation on Digital Media Evidence, highlighting the critical protocols investigators must follow to properly preserve and extract digital video evidence from NVR/DVR systems. He further discussed the types of analyses that can be performed after properly preserving and extracting the evidence, with a particular focus on reverse projection techniques using 3D point clouds and video superimposition. His presentation included several real-world case studies to illustrate these methods in action.

Following Mr. Healy's presentation, Mr. Cronin provided a one-hour session that built upon the Digital Media Evidence discussion. He presented real-life case examples demonstrating how proper forensic video analysis can be effectively integrated into accident reconstruction investigations. His talk emphasized the types of conclusions that can be drawn when these technologies are applied within the context of collision analysis and reconstruction.

September 2025: Matthe Healy Introtech’ s forensic video analyst recently completed a video reconstruction of a surveillance camera view of a motorcycle crash. Experts on the opposing side of the case calculated a significantly low speed for the motorcycle.  Introtech was asked to analyze the digital video to determine if a more accurate speed calculation was possible.

In order to make this process possible, Mr. Tomasheski and Danniger of the Introtech staff inspected the motorcycle and extensively documented the crash location utilizing total station, 3D drone point clouds and a Faro 3D scanner.  Once the scene, including the camera position developed into a 3D image, Mr. Healy employed the Axon Investigate software to remove distortion in the original video.  He then determined the accurate distance and time over which the motorcycle was in the field of view of the camera utilizing the reverse projection camera match overlay tool of Axon Investigate.

As a result of his scientific analysis, Mr. Healy determined that the motorcycle was traveling above the posted speed limit and arrived at additional conclusions relating to the actions of the motorcyclist.  After tendering Mr. Healy’s report, the case resolved favorably for our client.   

This case is a classic example of how important a proper and accurate video analysis is in the modern world.  Video cameras are everywhere, but digital video is more complex to analyze than old VHS tape.  Whenever video is available and necessary to consider, it is important to consider that there are very few legitimate forensic video analysists in the country, and Matthew Healy is one of the best in that field. 

August 2025: Henry Lipian and Thomas Tomasheski recently conducted an extensive investigation and reconstruction of a single vehicle cash involving an electric scooter, also known as a micro mobility device. We were advised that after tendering our report, the case successfully settled.  

Introtech conducted a detailed analysis of the damage and operating characteristics of the electric scooter. In order to define the after-crash situation in greater detail than what the police documented, the area was scanned with a Faro 3D scanner and a drone, where a 3-D point cloud was developed. Mr. Healy then conducted a camera match overlay analysis in conjunction with the police photographs, police body cam video and the Introtech 3-D point cloud and developed a scale after crash situation map.  Accurate measurements were then determined so that the speed of the electric scooter was calculated and other important metrics from the crash.

Extensive research into the operating characteristics and legal aspects of the electric scooters/E-bicycles was also conducted along with relevant portions of Ohio Manual of Uniform Traffic Control Devices, Ohio Roadway Design Manual and the Americans With Disability Act.  

With the proliferation of E-bicycles and electric scooters, whether they are single unit crashes or those involving collision with other vehicles, the population of these unique vehicles is growing.  The analysis and reconstruction of these crashes require specialized knowledge and methodology.  In addition to recently settled cases, the Introtech staff have a number of active cases in this category, and we are constantly evolving new investigative protocols and techniques for this unique category of vehicle.  

August 2025: For two years the Introtech staff has been working on a dramatic fatal crash that occurred near Philadelphia on the Pennsylvania Turnpike involving six vehicles, including a commercial tractor trailer.  The Pennsylvania State Police did a comprehensive investigation including drone imaging and total station mapping. However, additional investigative techniques were employed by the Introtech staff to answer the questions and issues that were relevant to our client regarding the liability of the commercial vehicle.

In that process, Introtech inspected all the available vehicles including 3D scans, and the segmented parts of the tractor and trailer.  Introtech conducted our own drone imagery of the crash location, imaged the available event data recorders (EDR) and analyzed the voluminous discovery data and depositions.  In addition to resolving the standard time/speed/distance/position elements of the crash reconstruction, our work also involved a human factors analysis and mechanical evaluation of the alleged steering problem with the commercial tractor, which was determined to be unfounded.

After a thorough and comprehensive review of the evidence and data that occurred over  the two years of our work on this case, Introtech prepared an extensive report.  Within two months of the issuance of our report, we were advised by our client that the case has settled favorably.  

August 2025: Matthew Healy conducted an extensive video analysis of three separate cameras that captured the actions of two vehicles before they were actually involved in the crash.  The crash was the result of a road rage incident between a motorcycle and a pickup truck that occurred in northeast Ohio. The local police department conducted an extensive and professional crash reconstruction; however, they needed assistance in the analysis of the video. Introtech has done cases for this prosecutor’s office in the past and they were familiar with Introtech’s capabilities in forensic video analysis. 

Matthew Healy worked closely in conjunction with the local police agency and the county prosecutor’s office.  Matthew and the Introtech staff utilized the photograph and drone imaging conducted by the police along with the Introtech additional documentation of the areas of interest in the video via drone and 3D scanning.  

Once the investigation was completed, Mr. Healy then utilized Axon Investigate software to conduct the three separate camera views in the reverse projection camera match overlay process.  Mr. Healy then determined the speed of the two vehicles, the spacing between them, the acceleration rates of both vehicles and the placement of the vehicles on the roadway in both lateral and longitudinal positions. Mr. Healy’s analysis was then incorporated into the law enforcement analysis to provide a more comprehensive analysis of the pre-crash as well as the impact phase of this crash sequence.

Mr. Healy testified in trial on behalf of the prosecution and the jury returned a guilty verdict on all counts against the defendant. Mr. Healy received a well-done for his work in the analysis, report, PowerPoint and his testimony at trial.

In May of 2025, Henry Lipian and Matthew Healy conducted four days of training for the Colorado Highway Patrol in Golden Colorado on the specialized topics of pedestrian and bicycle crash reconstruction and the basics of digital video.  The attendees were all Troopers of the Colorado Highway Patrol.  The topics ranged from speed calculations, human factors, bicycle/vehicle damage analysis, injury patterns, vehicle lighting systems, driver/pedestrian distraction issues, nighttime conspicuity, crash scene evidence and what every investigator needs to know about digital video.  The schooling was presented at the Colorado Heighway Patrol Academy and included the full staff of their Vehicular Crimes Unit.  Both Henry Lipian and Matthew Healy were presented with a Colorado Highway Patrol challenge coin and State Patrol patch.   Over the years Intratech staff has been actively involved in teaching a wide variety of crash reconstruction topics to various professional organizations and law enforcement agencies including the Montana Highway Patrol, the Kentucky State Police, Northcoast Polytechnic Institute, the Ohio Peace Officer Training Academy,  Cuyahoga Community College, St. Petersburg College amongst others.

In May of 2025, Henry Lipian was interviewed by the New York Post relating to the collision between the Mexican Navy Training vessel Cuauhtémoc and the Brooklyn Bridge in New York City.   Henry Lipian who is a retired Coast Guard Officer, Port Security Officer and former enlisted Chief Machinery Technician, has been involved in numerous maritime and boating accident investigations while he was in the Coast Guard as well as his work in the private sector.  This collision between the Cuauhtémoc and the Brooklyn Bridge has some similarities with the collision in 2024 in Balitmore with the Motor Vessel Dali.   In both cases Mr. Lipian was able to provide insight and information to various news media to assist in understanding the basics of the events.  Both collisions are still under investigation by the National Transportation Safety Board and generally take a year or more for the NTSB to release their recommendations.   Mr. Lipian's initial observations about the collision in New York were published in the May 18, 2025, on-line Edition of the New York Post. 

Starting in early 2023 and ending in November of 2023, Introtech staff in conjunction with Northcoast Polytechnic Institute conducted a full series of crash investigation and reconstruction training to Ohio Police officers starting with Crash Investigation Level I, through Crash Investigation Level II, Vehicle Dynamics and finishing with Crash Construction. These classes were taught at the training facilities of Eastlake and Brooklyn Police Departments. This intense training included field work, vehicle damage analysis, classroom studies, introduction to technology, mathematics, basic physics, human factors and specialized topics such as motorcycles, occupant restraint systems, pedestrian and commercial vehicles. A variety of instructors from the Introtech staff provided the instruction including Matthew Healy, Vince Cronin, Henry Lipian and Melinda Lipian.

In March of 2023, Henry Lipian was invited to present an important class to a northern Ohio Amish community on the topic of the new Ohio laws governing the marking and lighting of Amish buggies and wagons. In addition to going over the new laws, Mr. Lipian provided some case studies of Amish crashes that Introtech has investigated and provided a basic understanding of human factors, night visibility and conspicuity issues, retroreflective materials and lighting effectiveness and limitations, aging and fatigue factors for drivers. There was also a topic of instruction on driver distraction. The community group session was well attended by Amish leadership as well as the general population. A better understanding of the challenges presented to the motoring public encountering Amish vehicles, especially under night and limited visibility conditions, traffic laws was accomplished was achieved. Some of the concerns expressed by the Amish as to how the public should respond to their concerns was also expressed. 

In May of 2024 Matthew Healy presented an eight hour class: Digital Media Evidence – What Every Investigator Needs to Know, to a wide variety of law enforcement officers on the expanding and important technical subject of forensic video analysis. One of the goals of this training was to afford officers a better understanding of how to properly obtain, preserve and interpret important digital video including the correct chain of custody of digital video. The process of obtaining and analyzing digital video is increasing in its complexity, but also is providing far more advanced benefit to an investigatory analysis, as long as the video is properly obtained and properly analyzed. The old adage that in video what you see is what really happened, is no longer necessarily true. With variable frame rates, I,P and B frames, meta data analysis of each individual frame, correction of distortion in conjunction with 3D overlays and camera match superimposition. All of the offices came away from the training with important and critical new knowledge to improve their documentation and analysis of this important and evolving field. In the future Introtech is planning on providing a similar training program for the legal and insurance community and is in the process of obtaining continuing legal education credits for this new training program. The Accreditation Commission for Traffic Accident Reconstruction (ACTAR) has approved Mr. Healy’s training program for the police attendees.

As of June 2024, Introtech has a new staff member, Melinda Lipian who will be taking over some of the administrative duties from recently retired Timothy Kalish, who retired from Introtech with 30 years of dedicated service. Mrs. Lipian has a degree in mathematics from Akron University and is in the process of assisting Matthew Healy in processing digital video for his analytical use. Prior to coming to Introtech she taught mathematics at various public and private schools in Northeast Ohio. During Introtech’s recent Reconstruction training, she taught mathematics, basic trigonometry and co-linear momentum. In addition to learning the basics of forensic video she will also soon be taking classes in basic accident investigation. 

In the immediate aftermath of the Franics Cott Key bridge collision and collapse in Baltimore by the cargo ship Dali in Mach of 2024, Henry Lipian of the Introtech staff was interviewed extensively in both print and television media including local Fox News Stations and CNN. Local newspapers such as the New York Times and the Baltimore Banner and other print media interviewed Mr. Lipian in a number of articles. Mr. Lipian has extensive experience in naval engineering issues from his time as both an enlisted and commissioned officer in the United States Coast Guard and the Coast Guard Reserve. He has also been involved in private sector reconstructions of many maritime, shipping and boating accident incidents. Although many of the issues cannot be resolved so near to the time of the event, many foundational and basic issues were still able to be addressed. Obviously as the NTSB and other agencies continued their lengthy investigation, initial hypotheses and basic navigation/engineering and crew responsibilities were addressed by Mr. Lipian to the extent possible during the initial phase of the investigation. In addition, Mr. Healy of the Introtech staff has done some preliminary video analysis of the surveillance video of the collision.

Mr. Vincent Cronin has recently completed two new classes in two specialized reconstruction topics; Event Data Recorder Use in Traffic Crash Reconstruction Level I in January 2024 and Advanced Human Factors in Crash Reconstruction in October of 2023. Both of these educational classes were approved for ACTAR CEUs for Mr. Cronin as he prepares for his recertification process for ACTAR re-accreditation.

In addition to his certification as a Metrologist including reverse projection camera match overlay processing, in 2023 Mr. Healy completed his LEVA Level One certification class on his way to full LEVA certification. In July of 2024, Mr. Healy will be attending the LEVA Level Two certification in Pontiac Michigan. Mr. Healy is already the most knowledgeable and skilled forensic video analyst in Ohio, but as he progresses through his LEVA training, he will be one of the very few LEVA certified forensic video analysist in the United States. Mr. Healy has done extensive analysis of video for civil cases, criminal cases (both for prosecution and defense) and private sector clients. In addition to the LEVA training, Mr. Healy regularly attends on-line training from Axon Investigate, formerly known as Input Ace.
