Crime scene investigation is a field that requires the utmost care and keen eye for details, which could ultimately be the difference between justice being served and it being denied. However, collecting forensic evidences from a crime scene is still more of an art than a science and relies heavily on the experience of the people collecting evidence. To reduce the margin for human error in collecting evidence, designer Chin Zuozhi has created the System Rectitube Forensic Collection Kit.
The kit basically makes the collection of evidence from a crime scene more of an exact science than it is now. Made up of four parts, the kit is geared to collect liquid and solid samples as well as photographs of the crime scene. The sample collection device itself is fitted with a three point synchronized image capture function that allows collectors to mark the exact location from which a particular sample was collected. This function allows investigators in reconstructing the crime scene and mapping it out at a later stage.
When collecting evidence, the handheld device can be put directly over any kind of liquid or solid sample, which is sucked into a tube and collected inside it and sealed with anti tampering tape and cap connector. An LED UV ring light within the radius of the device’s nozzle allows the camera to capture a clear image of the location and the taken images can be instantly transferred to the tablet PC included in the kit via Wi-Fi. The camera can also capture a 360 degree panoramic image to better document the scene of the crime.
The System Rectitube Forensic Collection Kit also facilitates liquid state storage that allows investigators to collect larger amounts of evidence in liquid form like semi dried blood or other bodily fluids etc. A water proof membrane prevents vapor from the liquid evidence and a disposable nozzle that negates that chances of contamination. The kit also offers solid state storage which comes with mesh filtration that collects solid evidence and catches it in a 0.3 mm micron filter polystyrene membrane while excess air flow out the vents. In case the micron filter breaks, the device comes with an additional aluminum filter to serve as backup.
A critical part of the kit is the battery dock with nickel alloy connector that serves as a charging base for the handheld components. Also included in the set is a tablet PC that runs on an MS Windows OS with 1 GHz and has 500MB internal memory. The device comes with a capacitive multi-touch LCD screen with 800×480 resolutions that helps investigators review collected images and crime scene maps on the go. The device also has Bluetooth, Wi-Fi and quad band connectivity and comes preloaded with crime scene mapping software to aid primary evidence collection.
