In Ferguson, Missouri, police shot and critically injured an African-American teenager on Sunday night amid the protests commemorating the first anniversary of the death of Michael Brown. The St. Louis Post-Dispatch is identifying the teen as 18-year-old Tyrone Harris, a graduate of Normandy High School. Michael Brown also attended Normandy. Tyrone Harris’ father told the Post-Dispatch his son and Michael Brown were “very close.” The police say four officers opened fire on Tyrone Harris after he shot at them with a 9-millimeter gun that was recovered from the scene. A video posted to Twitter by a Ferguson activist appears to show a police officer standing over Tyrone Harris’ body as he lies on the ground, his hands cuffed behind his back, with blood on his white T-shirt. In the video, the activist pleads with the officer to get the young man some help.

Activist “Give him some help, man. Please, get him some help. He’s bleeding out, man. Please, get him some help, man. Please, get him some help, man. Please, get him some help. He’s bleeding out, man. You see it. He’s breathing, man. Please, get him some help.”

Harris was later taken to the hospital, where he remains in critical condition. Earlier in the day, protesters commemorated the death of Michael Brown with a four-and-a-half-minute moment of silence to mark the number of hours Brown’s body lay in the street. His father, Michael Brown Sr., also led a march this weekend and spoke about the continued struggle.

Michael Brown Sr.: “To be honest, I wouldn’t even care if they was listening or not. I just want to get on the TV and let them know I’m not stopping.”

Interviewer: “You’re not stopping. What does that mean?”

Michael Brown Sr.: “I’m not stopping.”

Interviewer: “What does that mean? Tell us what that means.”

Michael Brown Sr.: “Every time you turn on your TV, you’re going to see my face. So I’m trying to make it uncomfortable for people that think that this is OK to do this to us.”
