Rigor Mortis happens about 3-6 hours after death. It starts in the head, and goes down to the feet. It begins to leave through the feet and exits through the head. This has nothing to do with blood. That is post mortem lividty. Rigor mortis occurs as a result of a chemical change in the muscles of the decedent, causing them to become very stiff and difficult to manipulate.

Also, this has nothing to do with erections that is called a "priapism".
Because this person has been dead for 13 hours, rigor mortis has set in, and I am having trouble moving them.
