Moms and Mysteries: Jane Mixer 1969 murder case. 23-year-old University of Michigan law student (top 10% student, honor society) murdered while arranging ride home to announce engagement. Found staged in cemetery: shot twice in head, strangled with nylon stocking, belongings arranged with Catch-22 novel. Initial investigation chased 'David Johnson' (fake name from ride board) and considered Michigan serial murders. 2001 DNA testing revealed impossibility: match to 4-year-old Ruelas (60+ miles away) and to Gary Leiterman (never suspected). DNA contamination scandal emerges.
