Chicago group works to prevent violence in neighborhoods

CHICAGO (CBS) — A black truck was caught on video speeding off just moments after gunfire erupted in a West Humboldt Park alley.

Police said an 18-year-old died after being shot multiple times last night near West Ohio Street and Trumbull.

CBS Chicago spoke with a gun violence prevention worker who arrived minutes later. He said the shooting was the result of a personal disagreement that turned violent.

"Anytime that you have to settle a dispute with a gun, it's not necessary. We should be able to sit down and talk things out instead of using violence every time there is an altercation or a problem, said Frederick Wallace.

Frederick Wallace works with the Alliance of Local Service Organizations known as ALSO . Its mission is to make streets safer and work to prevent gun violence as well as de-escalate arguments in Chicago neighborhoods.

The organization provides families and victims of gun violence with resources following a shooting like this one.
