Because the 12th has come and gone and he never showed?
It is a dumb notation. Court records shorthand does not indicate why. Could have been other reasons. I am still looking into why he never showed because of some information given. So, you can save your smart aleck response because court records entered are sometimes inaccurate, incomplete.
Not to mention if an arraignment is scheduled, it does not disappear if the person does not show up.
