On July 17, 1844 Wilford Woodruff wrote about the death of President Joseph Smith. He said, 

“I have never shed a tear since I heard of the death of the prophets until this morning but my whole soul has felt nerved up like steel. I veiled my face and for the first time gave vent to my grief and mourning for the Prophet and Patriarch of the Church Joseph Smith and Hyrum Smith who were murdered by a gentile mob. After being bathed in a flood of tears, I felt composed.”

Wilford Woodruff had a very strong testimony of Joseph Smith as the prophet and mourned him greatly.
