(AP) — A 21-year-old Springfield man has been found guilty in the death of a friend in an accident while he was speeding over hills in an effort to make his vehicle go airborne. A Greene County jury on Thursday determined Matthew Hogue was guilty of first-degree involuntary manslaughter in the death of 29-year-old Kendi Highland and second-degree assault for injuries to another passenger, 21-year-old Joseph Sims, who was left paralyzed.
