It is generally believed that a crossroads was chosen as the site for burying the bodies of those who took their own life, or for executions, because the ghost of the departed would be confused and unable to find their way back to haunt the living. There is also, however, a less commonly discussed theory that says that because the victim of suicide or execution is deprived holy ground, this junction affords the slight sanctity of the sign of the cross (and possibly a wayside crucifix as well).
