Officers responded to calls at about 7:10 p.m. of a man with a gun inside the park, police said. Upon arriving, they encountered an armed man who allegedly pointed a gun at them. Multiple officers discharged their firearms and the suspect was pronounced dead at the scene from his injuries, Sgt. Danielle Newman said.
An additional weapon was found at the scene, police said. No other suspects were involved. Police Department homicide investigators, the Crime Scene Investigations Unit, the District Attorney’s Office and the Office of Citizen Complaints are involved in the investigation.
Nieto’s family declined to comment Sunday.
Nieto was a Buddhist and worked at the Bernal Heights Neighborhood Center, according to Jonathan Bonato, who said he knew him since 2008.
"He was a nice young man," Bonato said. "It's a huge shock and surprise to all of us."
Anyone with information on the incident is encouraged to call police at 415-553-1444.
Police are planning a town hall meeting early this week with Police Chief Greg Suhr, who was out of town Friday at the time of the officer-involved shooting.
The most recent officer-involved shooting occurred March 8 in the Mission district, where officers fired at the vehicle of San Francisco resident Jeffrey Ruano, 50, after he allegedly drove at them. Officer Adam Shaw was struck in the shoulder and it remains unknown whether he was shot by his partner or Ruano.
In another officer-involved incident in early February in the Dogpatch neighborhood, an officer shot at a suspect who allegedly stole a Saab and led them on a car chase before abandoning the vehicle.
