Donna Nez, 28, was shot and fatally wounded after answering a knock on an apartment door in Phoenix on Friday evening, April 18, 2014. She had been inside an apartment near 15th Avenue and Camelback Road with a friend and stepped outside after recognizing the person or people who knocked; gunfire followed minutes later. Donna, known to friends as Shorty, died en route to the hospital.

Witnesses reported seeing several people, described as multiple males and females, running from the scene, and investigators say the person who knocked was believed to be known to her. The Phoenix Police Department and Silent Witness appealed for tips, but no arrests have been publicly announced and the motive remains unclear.

If anyone saw activity around the complex that night or knew Donna’s acquaintances, can you share information that might help bring answers?
