Republican gubernatorial candidate and former Illinois State Senator Darren Bailey's family members were killed in a helicopter accident on Wednesday.
In a statement, Bailey's campaign said his son, daughter-in-law, and two of his grandchildren died in a helicopter accident in Montana. Bailey's two grandchildren were 12 and 7 years old.
The couple's third child was not aboard the helicopter and is safe.
His campaign said Bailey and his wife, Cindy, "are heartbroken by this unimaginable loss" and are "finding comfort in their faith, their family, and the prayers of so many who love and care for them."
Kathy Salvi, Illinois Republican Party chairman released the following statement:
"The Illinois Republican Party is lifting-up the Bailey family, their friends and community in prayer as we grieve the tragic loss Zachary, Kelsey, Vada Rose and Samuel. Please join us in keeping the Bailey family in our thoughts and prayers during this unimaginable time."
Last month, Bailey launched his campaign for the Republican nomination for Illinois governor in next year's election. Cook County Republican Party Chairman Aaron Del Mar will be Bailey's running mate.
Del Mar joined CBS News Chicago to address the tragic accident. He confirmed Bailey's son Zachary was operating the helicopter at the time of the incident.
"It's been a devastating and heartbreaking affair for the last 15 hours," He said. "His family was beautiful."
Del Mar confirmed Bailey is with his surviving 10-year-old grandson in Montana.
An investigation is underway to find the cause of the accident.
