TBH Stenhouse gives his version of the Parrish-Potter murders and the murder of Henry Jones and his mother.
T. B. H. Stenhouse, The Rocky Mountain Saints (London: Ward, Lock and Tyler, 1873), 469
A month after the Parrish murders at Springville, one Henry Jones and his mother, living at Payson (only a few miles from Springville), were both killed. They were accused of an unnamable offence, and both were shot. The mother was killed in the house, and the son was pursued and killed in a neighboring settlement. There was no attempt at concealment about it. The Parrishes, too, were properly "laid out" arrayed in "the robes of the priesthood," and were the subjects of a sermon. They are to come forth in the first resurrection, for they paid the atoning penalty, and are, therefore, entitled to the honours of the immortalized Saints!
