A Brownsville man died after he apparently suffered a heart attack before his pickup truck left the road and entered a pond in Fond du Lac. Shortly before 12:30pm Tuesday rescue personnel were called to a pond near the Highway 151 Bypass and Interstate 41. The driver and lone occupant, a 57 year old Brownsville man, was transported to St. Agnes Hospital where he was pronounced dead. According to the Sheriff’s Office just prior to the crash the man was talking to his wife on his cell phone and told her he thought he was having a heart attack and was driving to the hospital.
