The possibilities of additive technologies continue to amaze me. From creating alternative meats to automotive parts, shoe insoles, and even surgical models, these technologies have proven to be incredibly versatile. But one of the most intriguing applications of additive technologies is in the field of facial reconstruction.

In a previous blog post, I shared a story about a cold case in Ohio where 3D printing and facial reconstruction were used to identify a deceased woman and apprehend her alleged killers. Since then, the Ohio Bureau of Criminal Investigation (BCI) has continued to partner with The Ohio State University to identify human remains using this technology. And now, thanks to animation technology, the process has become even faster.

Recently, Ohio Attorney General Dave Yost announced these new advancements in forensic facial reconstruction at a press conference in Stark County. The goal of this technology is to provide law enforcement and the public with alternative images of unidentified persons, which can generate more leads and increase the chances of solving a case.

Sometimes, when detectives are dealing with unidentified remains, all they have to work with is a skull, which might not even be fully intact. In such cases, forensic artists like Sam Molnar are brought in to determine what the person may have looked like when they were alive. Molnar, who works as a forensic artist and intelligence analyst for BCI, relies on specialized training and information from anthropologists to sculpt the heads and faces of these unidentified individuals out of clay on top of 3D printed copies of their skulls.

However, obtaining these 3D printed copies used to be a lengthy process. It involved driving the skull to OSU’s Wexner Medical Center, having it CT scanned, and then delivering the scan file to the Digital Union at OSU for 3D printing. Additionally, the scan file contained a lot of unnecessary data, which added to the time taken for the printing process.

To address these challenges and expedite the process, BCI detectives teamed up with graphics researcher Jeremy Patterson and 3D animator Dean Hensley, both from OSU. Patterson and Hensley developed a computer program that uses photogrammetry to create a 3D model of the skull. This eliminates the need for a CT scan and significantly reduces the time required for printing.

The partnership between BCI and OSU has already yielded breakthroughs in previously unsolved cold cases. By leveraging their skills and abilities, Patterson and Hensley are making a valuable contribution to forensic investigations. Being able to use their talents to help bring closure to families and solve crimes is incredibly fulfilling for them.

The advancements in facial reconstruction made possible by additive technologies and animation technology are truly remarkable. Not only are these technologies helping law enforcement agencies identify unknown individuals, but they are also opening up new possibilities for solving cold cases. With continued innovation and collaboration between experts in the field, we can only expect further advancements in forensic facial reconstruction in the future.

Revolutionizing Forensic Facial Reconstruction: How Technology is Helping Solve Cold Cases

In the field of forensic science, advancements in technology are constantly changing the way investigators approach the identification of unidentified remains. One area that has seen significant progress is forensic facial reconstruction, which aims to recreate the likeness of a person based on their skeletal remains. Thanks to cutting-edge technologies like 3D printing, CT scanning, and photogrammetry, the process of creating accurate and detailed reconstructions has become faster and more accessible than ever before.

Traditionally, creating a facial reconstruction was a lengthy and complex process that required specialized equipment and staging of the object. “This took specialized equipment, equipment that was expensive,” explained forensic anthropologist Dr. Todd Patterson. “You had to specifically stage an object to go through this, and the object itself mattered.” However, thanks to recent developments in software, the reconstruction process can now be done using just a series of high-quality iPhone photos taken from different angles.

This breakthrough in technology has made the process accessible to virtually anyone with a cell phone. “Anybody that’s got a cell phone that has high-quality images, they can make a 3D object in minutes,” said Dr. Erin Henley, a forensic anthropologist. This means that investigators no longer need to rely on specialized equipment or travel to a specific location to scan a skull. Instead, they can simply snap images of the specimen on their cell phone and send them to experts who can quickly create a 3D model.

Not only does this new technology save time and resources, but it has also had a significant impact on solving cold cases. By using the 3D models created from the iPhone photos, experts can easily print copies of the skulls using 3D printers, such as the Digital Union’s UltiMaker system. These printed skulls can then be released to the public, with the hope that someone will recognize the individual and provide information that leads to their identification. In some cases, the reconstructions have successfully identified individuals who had been unidentified for decades.

But the advancements in technology don’t stop at 3D printing. The same software used to create the 3D models is also employed to generate photorealistic digital images of what these unidentified persons might have looked like. Factors such as skin tone, eye color, facial hair, and hairstyle can be altered to create the most accurate representation possible. In cases where investigators don’t have an exact age for the remains, age progression can also be done to simulate what the person might have looked like at different stages of their life.

Recently, a press conference was held to unveil a forensic facial reconstruction of an unidentified man whose remains were found in 2001. The man, believed to be a Black male between 21 and 44 years old and standing between 5 feet 4 inches and 6 feet tall, had been waiting for identification for over two decades. The reconstruction, possible thanks to advanced technologies, aims to provide closure to his loved ones and help authorities in their investigation.

The impact of these advancements in technology on forensic facial reconstruction is undeniable. As Stark County Sheriff George Maier put it, “I will tell you that most good police officers will tell you there’s nothing better than boots on the ground. People on the ground developing leads, but without this type of assistance, we would not be able to do our jobs.” Through the use of CT scanning, 3D printing, and photogrammetry, investigators are now able to bring justice to those who have been waiting for answers for far too long.

In conclusion, the progress made in the field of forensic facial reconstruction is a testament to the power of technology in solving cold cases. The ability to create accurate 3D models using simple iPhone photos and to generate photorealistic digital images has revolutionized the way investigators approach the identification of unidentified remains. Without the use of advanced technologies like CT scanning, 3D printing, and photogrammetry, these advancements would not be possible. Indeed, technology is providing hope and closure to families still seeking answers, and helping law enforcement agencies make significant breakthroughs in their investigations.
