UPDATE: The victims have been identified as 56-year-old Michael Brandt, 20-year-old Carlan Michael Brandt and 25-year-old Ashley Piena. All 3 resided in Henderson.
Family friends tell 13 Action News, mother Joy Brandt and Ashley's husband, Kekoa Piena, were also in the car, but survived the crash.
They said the family was coming home from a week long vacation and just miles away from their Henderson home.
"I heard that she was doing well. I also heard that she had accepted the news pretty well," said family friend, Mike Talbot.
An odd reaction for most, but not for this family who is strong in the Church of Jesus Christ of Latter-day Saints community.
Michael Brandt was an LDS educator who worked as a bishop for some time, while son Carlan had just returned from a 2-year-long mission trip.
"Mike and Joy have done so much and everybody knew them. They are people that were very serviceable," Talbot said.
The causes of death for all 3 is pending.
The family has set up a GoFundMe account. Those interested can also donate money at the Green Valley Ward under Bishop Chad Gubler.
