Crime Scene Reconstruction in 360░

Affordable new tools for photo-documenting any crime scene and recreating them in augmented reality is now possible thanks to VPiX CSI:360. It's already in use by the FBI and many police departments. Best of all, it lets your police departments use your existing Nikon or Canon digital cameras.

The crime scene: Overturned furniture, broken lamps and strewn glass across a blood stained carpet. A suicide note was found on the chair and a murder victim was downstairs. The perpetrator was found in the bathroom with self-inflicted knife cuts and had bled to death.

The CSI tech set up her camera, tripod and rotator in the center of the living room and began capturing images, rotating the camera every 90 degrees. In just (4) shots, she quickly and effortlessly captures a complete floor to ceiling, High Definition (HD) view of the crime scene using her Nikon D300, a Sigma 8mm lens and a precision 360° rotator.

Back at the lab, she stitches the four spherical images of each scene into a spherical panoramic projection that measures 6,000 pixels wide and 3,000 pixels tall.

She then takes the images into Adobe Photoshop and adjusts the shadow details and boosts the sharpness. The final step in the crime scene reconstruction is uploading the panoramas into their police department’s CSI:360 crime scene server whereby she adds the final touches — making the crime scene interactive and ready for the electronic courtroom.

She double clicks her mouse and adds yellow digital evidence markers. When they’re clicked on, it open up new info-box windows which, displays additional details found at that spot: Still photos showing blood drops, the evidence note, a spent 9mm casing and 9-inch knife.

The last step is taking the entire crime scene and exporting it as a CSI:360 2 Go project. The CSI tech clicks on the export button and the entire crime scene is downloaded to her Mac or PC desktop in a folder and she burns (2) copies of the crime scene and bags up one in an evidence bag. The 2nd CD is labeled with the crime scene case file and is later given to the DA’s office.

The DA’s office said her CSI team now “walks on water,” because they’re able to prosecute more bad buys in less time and at a lower cost to the city.

Forensic Podiatry (Part Two of Two)

THE DISCIPLINE of forensic podiatry—or, in other words, the examination of pedal evidence—has progressed significantly over the past ten years. It is no longer a question of “What can you do with a footprint?” but rather, “Who can we use to evaluate the footprint?” Cases involving pedal evidence, especially bloody footprints and issues of determining shoe sizing or fit issues compared to questioned footwear, have become more common over the past two or three years.
