It all started when…
In October 2008, when Dr. Laura was working with a North Carolina Sheriff’s Office to reconstruct the murder of a man named Timothy White. Mr. White was shot in the head and twice in the back of his left hip and left leg. The district attorney asked which shot was first, second, and third. The sequence of shots was the difference between charging First Degree Murder and seeking the death penalty versus Second Degree Murder.
Back then, Laura purchased fiberglass driveway markers and wood dowels from home improvement stores, spray painted them various colors, and taped string to their ends to demonstrate bullet paths. She used lasers to show trajectories, but without the ability to shoot lasers through the dowels, often she ran into trouble. For bloodstain reconstructions, she ran into similar challenges: She also used a floor lamp stand, tape, and string to reconstruct blood in flight of bloodstain distributions. Both of these methods led to droopy strings, they were primitive, and she knew she needed to invent something new.
Tubular Dowel Crime Scene Reconstruction
The first thing Laura knew needed improvement were the dowel rods for bullet path reconstruction. Spray painting wooden rods was just not cutting it. Laura wanted to shoot a laser through a dowel rod, but no dowels existed in the world of forensic science with that capability. Laura sought out a hollow dowel that would replace the solid ones. After experimenting by shooting a laser through a McDonald’s straw, Laura knew clear, hollow, dowels were the future of laser reconstruction.
With the help of so many outstanding contributors along the way, Laura launched the first “Tubular Dowel Crime Scene Reconstruction Kit” in Tampa, Florida at the 2009 International Forensics Conference (The IAI). In 2013, Laura reimagined tubular dowel crime scene reconstruction by taking her original system even further by inventing what the world knows today as Dr. Pettler’s Kaleidoscope Laser Reconstruction System.
Relaunch: Kaleidoscope 2022
In August 2022, again at the International Forensics Conference (The IAI), this time in Omaha, Nebraska, Dr. Laura and long-time colleague, Douglas Young, Thorton Police Department Senior Criminalist and 2020-2021 President of the Association for Crime Scene Reconstruction launched the newly remodeled Kaleidoscope System. The first upgrade since 2017, Dr. Laura and Doug’s presentation of the kits met with resounding success. Doug offers Kaleidoscope training and certification quarterly through the LPA International Forensic Institute at LPA Headquarters and at host agencies.
