According to Albert Tracy, John Cradlebaugh dismissed the grand jury due to General Johnston withdrawing Cradlebaugh's army escort, not due to Cradlebaugh being upset with the jury's performance.

Whatever the just merits of the case, from either legal or moral points of view, it has been conceded by Colonel Johnson [sic] at Camp Floyd that he will withdraw his troops from Provo. This, leaving the court of Judge Cradlebaugh with no element of protection, necessitates the speedy closing up of the cases in which he was making so noble a progress, together with the retirement of himself, and his marshals and assistants to safer quarters.
According to Captain Albert Tracy (army officer), Cradlebaugh dismissed the grand jury due to General Johnston withdrawing Cradlebaugh's army escort, not due to Cradlebaugh being upset with the jury's performance.
