The search for a Des Plaines, Illinois, woman remains actively underway in southwestern Indiana. Officials say 31-year-old Cathryn McGill was a passenger in a vehicle being driven by her husband 35-year-old Adam McGill when their pickup truck was swept off the roadway in flood waters on Highway 257 Sunday morning. Adam McGill was rescued but his wife couldn't be found. Indiana Conservation Officers have located what they believe to be the McGills' Chevrolet Colorado submerged in water about 75 yards from the roadway. Adam McGill was released from the hospital Monday after being treated for hypothermia. The search for Cathryn McGill concluded at nightfall Monday evening and is scheduled to resume at daylight today.
