UPDATE:
Thursday morning, St. Joseph County Police released the name of the woman killed in Wednesday evening's crash near Potato Creek State Park, citing speed as the primary factor causing the accident.
Katherine Lynn Thompson, 20, was a passenger in a car driven by a 17-year-old female. The driver apparently lost control of the car and it struck several trees and rolled over in the 66500 block of Oak Road.
Police said Thompson has a Lafayette, Ind., address, but recently had been staying in the South Bend area. The 17-year-old's name is not being released because of her age. Police said Tuesday the driver and Thompson are cousins.
St. Joseph County Police and Fatal Alcohol Crash Team investigators are still working to determine the vehicle's approximate speed at the time of the crash.
