Calvin Riley was a 20-year-old college student and baseball player who was fatally shot on August 6, 2016, at Aquatic Park near Ghirardelli Square in San Francisco. He and a friend were playing Pokémon Go shortly before 10 p.m. when a man who had been watching them approached and shot Riley in the torso. Paramedics could not revive him and he was pronounced dead at the scene.

Riley’s phone and wallet were left untouched, and there was no exchange of words, leading investigators to rule out robbery as the motive. Witnesses later reported seeing a man watching people from a distance earlier that evening; Riley’s friend recalled passing the man while playing. Authorities released a suspect sketch, asked about two vehicles seen nearby—a dark-colored Audi A3 wagon and a white four-door Hyundai Sonata—and offered a $110,000 reward, but the case remains unsolved and open.

Riley had pitched at Junipero Serra High School in San Mateo and for San Joaquin Delta College in Stockton; his family remembers his love of baseball and Boston teams and continues to seek answers. Did anyone see the two cars or the man near Aquatic Park that night?
