Bullets and casings found at a scene require a known example to compare to in order to match them to a weapon. Without a weapon, the striation pattern can be uploaded to a database such as the National Integrated Ballistic Identification Network (NIBIN) maintained by the ATF or the United Kingdom's National Ballistics Intelligence Service ...
Calvin Hooker Goddard (30 October 1891 – 22 February 1955) was a forensic scientist, army officer, academic, researcher and a pioneer in forensic ballistics.He examined the bullet casings in the 1929 St. Valentine's Day Massacre and showed that the guns used were not police issued weapons, leading the investigators to conclude it was a mob hit.
