Burned corpse with erect penis
I have no information about the murder or accident.
The phenomenon of penile erection after death is known as post-mortem erection or rigor erectus. This is a rare occurrence but can happen in certain cases of death, particularly when the deceased is in a prone position or when there has been severe trauma to the central nervous system.
After a person dies, a process called rigor mortis (the stiffening of muscles after death) begins to set in, which can cause muscle contraction, including in the muscles of the penis. This can lead to a post-mortem erection. This phenomenon is often observed in cases of suicide by hanging or in deaths resulting from severe injury to the central nervous system.
