Alejandro Alex Nieto, 28, of San Francisco was shot and killed on March 21, 2014, in Bernal Heights Park. Nieto was sitting on a bench eating dinner before work as a bouncer when a couple walking their dog reported seeing a man with a gun. Officers who responded confronted Nieto; he was wearing a red San Francisco 49ers jacket and carrying a holstered taser for his job. According to reports, officers say Nieto pointed the taser at them and they fired, killing him after mistaking the taser for a firearm.

The San Francisco County District Attorney’s Office declined to file criminal charges against the four officers involved, concluding they reasonably believed they were in danger. Nieto’s family filed a federal civil rights wrongful death lawsuit, Nieto v. City of San Francisco, which went to trial in March 2016 and resulted in a jury verdict for the officers. The shooting prompted protests and sustained calls for changes in police training and accountability.

If anyone knew Alex, was at Bernal Heights Park that evening, or has information about what led to the confrontation, please share what is known.
