UPDATE: Semi driver had a medical condition

The Marshall County Coroner’s Office investigated a fatal truck accident Friday on U.S. 31 south of Argos, where 61-year-old Jerome D. Seward of South Bend was pronounced dead.
Seward was southbound on U.S. 31 when, according to witnesse,s he suddenly veered to the right shoulder and down an embankment ending up just short of the Topps Manufacturing parking lot. A witness to the accident approached Seward in the cab of his truck and started CPR. Argos Fire and EMS and Police responded immediately and asked that the coroner’s office be contacted. Marshall County Coroner Bill Cleavenger pronounced Seward dead at the scene. An autopsy was conducted from the coroner’s office and preliminary reports indicated that Seward had suffered an acute medical condition immediately before the accident. Preliminary results indicate he died of natural causes and not as a result of the accident. No one else was involved and the accident remains under further investigation. Argos Fire and EMS were assisted at the scene by the Argos Police Department, MCSD officers and the Indiana State Police.
