Abstract
A method of mathematically estimating the center of a position trajectory of an object generating a swing cast-off spatter includes obtaining position coordinates of a plurality of bloodstains to be analyzed, calculating collision angles of the plurality of bloodstains, generating straight lines based on the position coordinates and collision angles of the plurality of bloodstains, generating a triangle by selecting three of the generated straight lines, and generating an escribed circle of the triangle and calculating center coordinates and a radius length of the escribed circle.
