Lake County Sheriffs Police continue to investigate a motorcycle crash in far south Lake County that claimed the life of a Lowell man Sunday evening. Officers were called out to US 41 near 221st Avenue shortly before 6:30 pm. Police say the motorcycle was occupied by the driver only, and that individual, identified as 61-year-old Adam Szczepanek, was pronounced dead at the scene. Police say no other vehicles were involved. As officers began their on-scene investigation, police say they observed tire marks in the gravel shoulder leading up to where the motorcycle came to rest. The motorcycle, officers say, had been southbound in the outer lane of US 41 and exited the roadway to the west, and the reason for loss of control is unknown at this time. Officials say the driver was not wearing a helmet.
