So far, one teenager, 17-year-old Robert Mitchell, has been charged with first degree murder and armed criminal action. Two others have been accused of the crime.
Police say they have the name of a fourth suspect believed to be involved with the brutal beating.
Outraged with news of the hammer attack, hundreds of protestors took to the streets carrying signs and marching for peace and justice Monday night.
The crowd in the Bevo Mill area, home to tens of thousands of Bosnians, chanted,
"'What do we want: peace; when do we want it now!'"
Some Bosnian residents expressed that they came to the United States to escape violence in their home country.
The victim’s sister, Denisa Begic, 23, told the St. Louis Post-Dispatch Sunday night,
“[Begic] loved America. We come from Bosnia because we were getting killed and our homes and families were getting destroyed. Never in my life did I think he would get murdered.”
Bosnian residents say they feel unsafe and want help from the police to prevent any further harm to their community.
At the march Monday night, Bevo Mill resident Denis Kosdic said, “This is the way to go, peaceful. We moved to south St. Louis and it was in pretty bad shape and we started building our community, so for something like this to happen in our community it's just really sad."
St. Louis Police Chief Sam Dotson reportedly told protestors that the killing did not seem to be motivated by race or ethnicity, but appeared random.
"Maybe even words were exchanged when the victim drove away they kicked at his car and he got out of his car and then the violence ensued," Dotson said.
A recently discovered video features a phone recording of the aftermath, the ambulance performing CPR on Begic and hurriedly carting him away from the scene.

The person recording the video provides new details of the incident, claiming that she heard a number of “black people running up and down the street yelling, ‘f the white people, kill the white people’” directly prior to the confrontation.
The police have yet to release a motive.
