Delano Marquise Mathis was 22 when he was killed in a shooting near Sky Harbor Airport in Phoenix on the evening of October 25, 2018. The attack also took the life of 47-year-old Perry Sueing. Delano, born March 18, 1995, was remembered for his wide smile, a love of making people laugh, enthusiasm for basketball—especially the Bulls—and musical ambitions. He also cherished his children and had a close bond with each of them.

The Phoenix Police Department opened an investigation, but reports do not include a publicly disclosed motive or detailed circumstances that led to the shooting. The unresolved double homicide left Delano’s family and community with many questions.

If anyone knew Delano, saw activity near Sky Harbor on October 25, 2018, or has information that could help, please come forward.
