It's something straight out of an episode of CSI: An orange gun fires a green pellet that carries DNA traces, which, according to the manufacturer, lasts on a target for weeks, making it easier for authorities to identify him or her.

Called the SelectaDNA High Velocity System, the gun uses non-lethal bullets. It is useful in situations where police are having difficulty catching a particular target on the spot.

"On contact with the target, the uniquely-coded SelectaDNA solution leaves a synthetic DNA trace mark that will enable the relevant authorities to confirm or eliminate that person from their involvement in a particular situation and could ultimately lead to arrest and prosecution," Andrew Knights, managing director of UK-based gun developer Selectamark, said in a release.

Selectamark offers the gun in both pistol and rifle models, and claims it has a range of 98 to 131 feet. Check out the video, above, for more.
