The police officer involved in a shooting that left a teen dead Saturday in Ferguson, Missouri, has been placed on a paid administrative leave during the investigation, but will be available to talk to county homicide detectives.

Witnesses decried the killing as unprovoked. The deceased, Mike Brown, 18, was unarmed. Brown was spending the summer in the neighborhood with his grandmother, Desuirea Harris. He was walking with at least one other man at the time of the incident. Witnesses said that a police officer in a squad car grabbed Brown while he was walking.

The incident happened Saturday afternoon in the Canfield Green Apartments. The shooting happened in the middle of the Coppercreek Road.  Witnesses indicate that despite having his hands in the air, the officer fired ten shots several of which punctured Brown in the head and torso.

Angry residents took to the streets by the hundreds to protest, and Ferguson police called up more officers to secure the scene, Police Chief Thomas Jackson said.

Jackson asked the St. Louis County Police Department to conduct an independent investigation into his officer’s actions and the killing of Brown.

At the peak of the spontaneous street protest, up to 1,000 people turned up. It took the police officers hours to secure the scene for county homicide detectives to get evidence safely before removing Brown’s body.

Ferguson Police called for assistance from St. Louis County and nearby municipalities as large, emotional crowds gathered at the scene. In all more than 100 officers from 15 departments responded to the area. Tactical teams in riot gear were also called in. Through the afternoon and evening some among the crowds were yelling profanities at police demanding justice.

Protesters also turned to social media to get their message out. On Twitter, some complained about the time it took authorities to remove Brown’s body.

There were several false reports in the media regarding the incident, as well. The AP reported that residents of Ferguson had a confrontation with the police that lasted several hours. However, there were no reports of additional injuries or activity outside of the peaceful protests of community members. Several outlets including The AP, AOL and The Chicago Tribune reported that protestors chanted “Kill the Police” during the demonstration depicting the crowd as an angry mob.

Witnesses and the St. Louis Post-Dispatch reported that a group of around 100 mourners gathered outside the Ferguson Police Department later Saturday evening and were actually chanting “No Justice! No Peace!”
