The son of a prominent KSL employee died Tuesday in Washington County after a police officer deployed a Taser when the man ran down a road in what authorities called an "agitated" state.

Brian Layton Cardall, 32, was traveling with his wife south on State Road 59 near Hurricane on Tuesday afternoon. According to KSL.com, the vehicle pulled over to the side of the road when Cardall, who recently had been struggling with mental health issues, began having an "episode."

Cardall left the car and ran down the road, and his wife called police, said Washington County Undersheriff Jake Adams. A Hurricane police officer who responded to the scene deployed a Taser on Cardall, who lost consciousness, Adams said.

Cardall was treated at the scene but he was pronounced dead after being transported to Dixie Regional Medical Center in St.George, Adams said.

The Washington County Sheriff's Office did not immediately release further details about the incident.

Cardall is the son of KSL Editorial Director Duane Cardall, according to KSL.com. Attempts to reach Duane Cardall for comment Tuesday afternoon were unsuccessful.

Duane Cardall's administrative assistant said he and his wife, Margaret, were traveling to St.George late Tuesday to be with his son's wife, who is six months pregnant.

Adams said the Washington County Critical Incident Task Force is investigating Cardall's death.

The Hurricane Police Department did not return a phone call requesting comment on the officer who deployed the Taser.

A family statement released by Paul Cardall, Brian's brother and a renowned pianist from Sandy, read, "Brian is a wonderful son, brother, father, and husband who loved being with people. He was full of personality and wanted to make a difference in this world. He was working on his Ph.D. in Molecular Ecology at Northern Arizona University. He loved being in the outdoors and with his daughter Ava and beautiful wife Anna. We will miss Brian but are comforted by our faith."
