David Scott Anderson, 30, was fatally shot while walking in his Tucson neighborhood on May 1, 2021. Officers found him in the 1100 block of East Waverly Street; the Tucson Police Department investigated the shooting as a homicide.

Anderson was an accomplished young man: a University of Arizona alumnus who graduated Magna Cum Laude, earned a Master’s Degree with honors, taught at Sahuaro High School for two years, and was preparing to start a June internship with American Express. He tutored children, volunteered teaching English to immigrants during the pandemic, was a published author, and held a Blue Belt in Jiu Jitsu.

Police identified a suspect, 18-year-old Maurice Diaz-Casales, who was arrested five days after the shooting and was found in Anderson’s four-door sedan; initial charges included felony flight from law enforcement and later first-degree murder. The family has asked the public for information that could help the investigation. Does anyone have tips or recollections from that neighborhood on May 1, 2021, that could help?
