There was shooting at a Colorado supermarket, in which 10 people were killed on Monday, including a police officer, and a suspect who was in custody, authorities said.
Maris Herold, the Boulder police Chief announced the death toll at a news conference Monday night, fighting back tears.
The authorities disclosed that the suspect was getting medical treatment and there was no further threat to the public.
Officers had escorted a shirtless man with blood running down his leg out of the store in handcuffs but authorities would not say if he was the suspect.
The officer who was killed was Eric Talley, 51, who had been with Boulder police since 2010, Herold said.
Victims’ families were still being notified so their names weren’t released, Boulder County District Attorney Michael Dougherty said.
“This is a tragedy and a nightmare for Boulder County, and in response, we have cooperation and assistance from local, state and federal authorities,” Dougherty said.
Yamaguchi said police were still investigating and didn’t have details on a motive for the shooting at the King Soopers store in Boulder, which is about 25 miles (40 kilometers) northwest of Denver and home to the University of Colorado.
