Seven activists who in recent months have protested brutality, gathered on the South Side on Monday afternoon to decry the killing of Arshell Dennis, the 19 years old son of a Chicago police officer.

Activist Ja'Mal Green said , "This young man was taken supposedly by our own, and we're going to stand up for (Dennis). We want this killer to be brought in so that we can have justice. Because (Dennis) didn't deserve this. Nineteen years old. Nineteen."

Green was arrested last month during a protest of fatal shootings by police and charged with hitting one police officer and trying to disarm another.

He was among the activists who met at the corner of West 82nd Street and South Sacramento Avenue in the Wrightwood neighborhood, where Dennis was shot and killed on Sunday morning..

According to police officials, Dennis and a friend were hanging out on the front porch of a residence when a gunman approached, from inside of a vehicle, and opened fire. The friend, 20 years old, was shot in the arm and side.

According to police spokesman Anthony Guglielmi, the victim's father, Officer Arshell "Chico" Dennis, and Superintendent Eddie Johnson worked together as patrol officers in the Gresham District.

Guglielmi  said that, Dennis' death has been investigated as a case of mistaken identity, based on what detectives know about Dennis' family, about that block and about the neighborhood.
