Arrest made in shooting death of Chicago officer's son

CHICAGO (AP) — An 18-year-old who police say is a gang member was arrested Friday in the shooting death of a Chicago police officer’s teenage son.
Investigators believe 19-year-old Arshell Dennis III was killed because he was mistaken for a member of a rival gang. Anthony Moore is charged with first-degree murder in the August killing.
Dennis was shot in the chest as he visited with friends on the porch of his parents’ Chicago home just hours before he was to return to college
