Jimmie Johnson, seven-time NASCAR Cup Series champion, is mourning the devastating loss of his in-laws and nephew in a tragic incident. His mother-in-law, Terry Janway, is suspected of fatally shooting her husband Jack Janway and their grandson Dalton before taking her own life in what authorities describe as a murder-suicide. This heartbreaking event follows a previous family tragedy when Chandra Johnson’s brother, Jordan Janway, died in a skydiving accident in 2014. Jimmie Johnson’s racing team has withdrawn from upcoming races as the family processes this loss.
