Walorski, 58, communications director Emma Thomson, 28, and district director Zachary Potts, 27, were all killed in a Wednesday head-on collision in Elkhart County, Indiana.
Edith Schmucker, 56, the sole occupant of the colliding vehicle, was also killed. Elkhart County Sheriff's Office released updated information Thursday that corrected what the office initially said Wednesday.
All occupants of both vehicles were wearing seat belts, the office said, and Potts was driving the Toyota RAV4, with Walorski and Thomson as passengers.
