We now have been told by the Putnam County Sheriffs Department that 82 year old Willie Simmons and 61 year old Keith Simmons were both from Sullivan.
Willie Simmons died at Methodist Hospital last night as a result of his injuries.
A fatal accident Sunday morning on Interstate 70.
Police say that 42 year old Michael Sullivan of Franklin was killed when he crossed into on-coming traffic and collided with another vehicle at the 42 mile marker near Greencastle.
Police believe that rain, slick roads and the fact that the driver may have fallen asleep at the wheel may have all played a part in the accident.
The occupants of the other vehicle, Willie Simmons and his son, Keith Simmons were sent to Methodist hospital in Indianapolis, both with lower leg and hip injuries.
