As far as I can tell, no. There was an 1894 article after Bolton became police commissioner of Norfolk Va. which briefly related his military service, without mentioning being at the theater when Lincoln was shot.

I did look into Bolton's character reference and he is the absolute opposite of a "reliable witness":

Since he did serve with Bolton at the time he could've been Bolton's, unfortunately, only locatable witness at such late a date or a former comrade amenable to lying.
