Several hundred residents descended on the St. Louis County prosecutor’s office in the latest heated protest of the weekend shooting by an officer of 18-year-old Michael Brown.

Standing on the steps of the county building, the protesters chanted “no justice, no peace,” before taking to the streets.

“Hands up, don’t shoot,” they yelled as they made their way through downtown Clayton.

Later, they came face to face with officers guarding the prosecutors’ office, chanting “Who do you serve? Who do you protect?”

The large demonstration was the latest boil-over of frustration in the four days since Brown was killed — a shooting about which few details have been released.

“Every time I hear about these shootings, I think that it could have been me,” said Gianni Cook, 18, who attended the protest with a sign asking: “Am I next?”

Residents remain outraged that Brown was shot, allegedly shot multiple times, while unarmed. The officer who killed him has not been identified, and local law enforcement has not released a detailed narrative or timeline of the shooting.

“This ain’t just about an officer killing a brother,” said Malik Parker, 46, who marched in the demonstration. “This is about something bigger that we’ve all got to deal with.”

At one point, the racially diverse group of protesters sat down in a straight line with their hands above their heads chanting, “Hands up, don’t shoot!”

Civil rights leaders and Brown’s family have called for a federal investigation into the shooting. Residents, meanwhile, say the shooting is disturbing but not surprising.

“It’s murder. Anytime you shoot somebody, a young boy, for something he shouldn’t even be arrested for, that’s murder,” said Janet Cuenca, 76, a retired teacher.

“I want to see this officer out on trial!” She added.
