Results: In Partial Hanging, The Major Position of the Ligature Mark, in 86% [n-153] cases was across the Thyroid Cartilage and was Nearly Horizontal in the Front. Wheras, In Complete Hanging Majority of the Ligature Mark, 92% [n-420], were situated above the Thyroid Cartilage. In 81% [n-369] of cases of Complete Hanging and 73% [n-130] of Partial Hanging, the Ligature Mark was Incomplete. In 38% [n-68] of Partial Hanging the Ligature Mark was Limited to the Front of the Neck whereas in 13% [n-59] of Complete Hanging it was limited to the Front of Neck. The Petechial Hemorrhages in Ligature Mark due to Complete hanging were Absent. A Slip Knot was used on 97.73% [n-620] of suspensions.
