Kaitlyn Arquette was 18 when she was shot on July 16, 1989, in Albuquerque, New Mexico. She was driving home from a friend’s house and was shot near the intersection of Lomas and Broadway; she succumbed to her injuries the next day. Duncan examined multiple theories, including a possible link to a Vietnamese gang and to Kaitlyn’s boyfriend.

For more than three decades the murder remained a cold case. The key details known are the date, location, method (shooting), and Duncan’s ongoing public campaign to find answers.
