When examining a sample of glass fragments recovered from a suspect in a forensic
case, many questions arise: "Did this man break that window?", "Are these fragments
from the crime scene source?", "Do the fragments recovered from the suspect come
from more than one source?", "How common is it to find glass on someone unrelated
with crime?" etc. Such questions are usually answered with the help of statistical
methods. This paper reviews some of the statistical solutions and problems
encountered in the interpretation and evaluation of forensic glass evidence.
