The family of a man fatally shot last year while playing Pokémon Go will appear at Aquatic Park this morning with Congresswoman Jackie Speier (CA-14) to announce a $50,000 reward for information that will help identify the person who killed Calvin Riley nearly a year ago.

On the night of August 6, 2016, Riley was in the park with other friends playing the popular smartphone game when he was shot by an unknown assailant. Riley, a 20-year-old college student from San Mateo, died at the scene.

No suspects have been identified in the shooting, which occurred when many people were in the park playing the game. After the incident, investigators said they hoped surveillance footage or witnesses would help identify a suspect.

Sean and Kariann Riley, the victim's parents, will be at this morning's press conference, along with Speier and representatives from US Park Police.

“With the generosity of the city of San Francisco, I am hoping that witnesses will step forward and help solve this homicide,” Speier said in a statement.

“While the capture of the killer won’t bring back their son, the Rileys would have some closure involving this horrific loss to their family," said Speier. "Importantly, residents of San Francisco would also have certainty that a killer is removed from their streets preventing this person from killing again.”

Because Riley was killed in Aquatic Park, investigators from the San Francisco field office of the US Park Police are taking an active role. Park Police detectives also handle criminal investigations at Crissy Field, Ocean Beach, the San Francisco Maritime Museum and in the Presidio.

[Update: 12:52pm] ABC7 is reporting that US Park Police has contributed $10,000 toward the reward, and Sean Riley has contributed $50,000, which means the city's contribution raises the total reward to $110,000.
