Roger Miller, son of the late founder of Miller Motorsports Park Larry H. Miller, who raced in the Grand-Am Continental Tire Sports Car Challenge, died Sunday at age 45, the family announced. The cause of death was not made public.
"Roger was a gentle soul and he will be missed," said his brother Greg Miller in the family's statement.
Roger Miller served as the Chief Technology Officer of the Larry H. Miller Group of Companies and had worked for his father's company for 28 years, but had increasingly focused on his pro racing career. This year he teamed with Ian James in a Dempsey Racing-prepared Mustang in the Continental Tire series, and finished 11th in the GS-class car at Saturday's race at Kansas Speedway.
Team owner Patrick Dempsey tweeted: "All of Dempsey Racing is saddened by the loss of our friend, racer and teammate, Roger Miller. Our thoughts are with his family and friends."
