"We are saddened by the tragic deaths of members of Chandra Johnson's family," NASCAR said in a statement to E!. "The entire NASCAR family extends its deepest support and condolences during this difficult time to Chandra, Jimmie and the entire Johnson & Janway families."

Following news of the local deaths, Muskogee Mayor Marlon Coleman addressed the tragedy. 

"It was traumatizing to find out that a long-standing family who had made so many contributions to our community were involved in this type of incident. It was even more bone-chilling to find out there was a child involved," he told Fox23. "I knew Dr. Janway. Dr Janway has worked on me, we've been acquaintances for a very, very long time since I've been in Muskogee. Just knowing that it was him and his family took a different toll on me."

E! News has reached out to Jimmie's rep for comment and has not heard back.
