Roger Miller, the son of late Utah Jazz owner Larry H. Miller, died on Sunday at age 44, Yahoo! reported.
In a statement released late Sunday, his family described him as a "gentle soul" who will be deeply missed. It did not disclose details on how Miller passed away.
He's survived by his mother, wife, five daughters, four sons, and three grandchildren. He would have turned 45 on Aug. 21.
The Miller family has played a significant part in Utah sports and business for a while. In addition to owning the Utah Jazz, they also own the Salt Lake Bees AAA-baseball team, the Tour of Utah bike race, Miller Motorsports Park, Megaplex Theaters, Fanzz sports apparel store, and multiple car dealerships.
The family has also been active in philanthropic causes and spent a significant amount of time and money on charity projects. Larry H. Miller donated $21 million to a law enforcement training center and invested in a Salt Lake Community College campus, which is named in his honor.
Roger Miller was one of five children born to Gail and Larry Miller. His father died in 2009 at the age of 64. Now, Roger Miller's brother, Greg, is in charge of the family business.
On Aug. 20, Greg Miller tweeted "I must publicly express gratitude for the overwhelming display of love & support from employees of the LHM org in the wake of Roger's death."
Linda Luchetti, a spokesperson for the Larry H. Miller Group of Companies, said Roger Miller worked for the family business in various positions for the past 28 years. He served as the chief technology officer for a while and developed ticket kiosks at their Megaplex theaters.
Luchetti also mentioned that he had recently been focusing on his passion for car racing. Back in January, Roger Miller and a co-driver competed in the Grand-Am Continental Tire Sports Car Challenge Series at the Daytona National Speedway and finished in 10th place.
Family members said he also loved to camp, ride ATVs, scuba diving, and skiing. Plans to hold a memorial service have not been determined yet, according to Luchetti.
