A young man from Cache County has died while serving a mission for The Church of Jesus Christ of Latter-day Saints, church officials announced Wednesday.

Brennan Conrad, 18, from Hyde Park, fell Wednesday from the roof of his apartment building and died in Santo Domingo, in the Dominican Republic, a church spokesman said.

Conrad had been serving in the Dominican Republic Santo Domingo East Mission since August.

Conrad was a “very bright, very happy, optimistic young man,” said Mario Durrant, president of the church’s Hyde Park Utah Stake, which Conrad attended. “He was a tremendous missionary. He was having great success, and [the other missionaries] loved it.”

Durrant said Conrad had spoken to his family by phone Monday, after a church announcement last week that missionaries could contact their families weekly via phone and text. Before the policy change, missionaries could call home only on Mother’s Day and Christmas.

“It meant a lot to the family that they were able to talk to him by phone on Monday,” Durrant said. “He was really happy — they kept saying that over and over.”
