SAN FRANCISCO -- Two police officers shot and killed a man carrying a knife in the San Francisco's bustling Mission District on Thursday, the city's police chief said.
San Francisco police Chief Greg Suhr said officers shot the unidentified Latino man after he refused demands to drop a knife and after the suspect was shot four times with nonlethal beanbags full of pellets.
The incident was the third fatal shooting of a minority suspect not carrying a gun in the last two years and the second since December.
The previous two shootings along with two separate scandals involving officers exchanging homophobic and racist emails has led to several protests, calls for the chief's firing and wrongful death lawsuits.
The U.S. Department of Justice recently agreed to requests from Suhr and Mayor Ed Lee to review the department's procedures and policies. Suhr has called in outside law enforcement experts to help the department develop less lethal responses to suspects not carrying guns.
The latest incident began Thursday morning when city homeless outreach officials checking on residents living in tents called police to report a man carrying a knife, Suhr said. Suhr didn't identify the man, who officers reported charging at them before firing.
Seven bullets casings were found and the kitchen knife recovered, Suhr said. The blade was 10 inches to 12 inches long, and witnesses described it as a chef's knife, he said.
Two witnesses say a language barrier may have contributed to the shooting. John Visor and Stephanie Grant said they lived in a tent in the same encampment as the suspect and say he spoke only Spanish and that the officers barked their commands to drop the knife in English.
Visor, 33, and Grant, 31, say the man was confused and walking in a circle when the officers hit him with the beanbags and then opened fire with guns. They say the man had stuffed the knife into his waistband before he was shot.
"Everybody carries something for protection here," Visor said. "He didn't have the knife in his hand when he was shot."
Visor and Grant knew the man only as Jose. They said Jose liked to collect bottles and cans for recycling and enjoyed kicking a soccer ball, sometimes late into the night and to the occasional annoyance of pedestrians.
"He never hurt anybody," Visor said. "He just liked to pick up cans."
The mayor said in a statement that "we are all striving to make sure officer involved shootings are rare and only occur as a last resort." Lee said he has requested an independent investigation from the Office of Citizen complaints in addition to the customary investigations by the Police Department and district attorney.
The last previous fatal shooting that involved San Francisco police occurred on Dec. 2, when five officers fatally shot Mario Woods 20 times, including six times in the back, in an incident caught on video.
Woods' family has filed a wrongful death lawsuit.
On Wednesday, the city's police commission agreed to reconsider its ban on arming San Francisco police officers with stun guns because of the Woods incident and the 2014 police shooting death of Alex Nieto, a college student carrying a stun gun that officers mistook for a handgun. Nieto carried a stun gun for his job as a security guard.
A federal grand jury earlier this year ruled the officers acted appropriately and refused to award Nieto's family any damages after a trial in San Francisco.
San Francisco is one of only two of the nation's largest cities that do not equip officers with stun guns.
