Police responded after Quinones ran a red light and wouldn't pull over, the Minneapolis Star Tribune reported. According to emergency dispatch audio, Quinones continued running through red lights in Richfield.
After police forced the car to stop, Quinones got out holding what appears in the video to be a large knife in his left hand. In the dispatch audio, officers can be heard yelling, "Drop the knife. Drop the knife." Shots can then be heard before they say, "Shots fired. Shots fired."
Quinones seemed calm and expressionless during the chase, sometimes glancing in the rearview mirror. Just before the livestream, he posted on Facebook, "So sorry." No officers were hurt. The Hennepin County Sheriff's Office is investigating and declined comment Sunday.
"The Edina and Richfield Police Departments express our thoughts and prayers to all those involved in this tragic incident," the departments said in a joint release. A crowd gathered at the scene after the shooting, which happened behind an apartment complex. Some in the crowd shouted at the police as dozens of officers lined up behind police tape to keep order.
On Sunday evening, local media outlets reported that a small group of demonstrators briefly shut down part of Interstate 494 to protest the shooting. The Minneapolis-St. Paul area has had several police-involved shootings in recent years that have sparked angry protests, including the 2016 killing of a black driver, Philando Castile, by a police officer in the Twin Cities suburb of Falcon Heights. Castile's girlfriend streamed the immediate aftermath of the shooting live on Facebook.
In July, top Minnesota law enforcement officials announced they were launching a working group and public hearings to find ways to prevent and respond to fatal encounters with police. Minnesota Attorney General Keith Ellison, a Democrat, and Public Safety Commissioner John Harrington are leading the 16-member group. Protesters disrupted the group's first meeting in August, saying the group was skewed toward lawmakers and law enforcement, and needed more representation by families affected by police shootings.
