A preliminary investigation reveals that a Chesterton man who crashed his vehicle early Saturday morning on the Borman, may have died as a result of some sort of medical emergency. Sgt. Ann Wojas of the Indiana State Police says at around 1:45a.m. a Toyota Camry driven by 54-year-old Timothy Knight of Chesterton was eastbound on I-80/94 just west of Calumet Avenue when he suddenly veered right crossing lanes of traffic hitting the outer barrier concrete wall and coming to rest in the deceleration lane. Knight was reportedly found unconscious and not breathing after the crash and pronounced dead at Munster Community Hospital. An autopsy has been scheduled.
