CHICAGO (CBS) — Protesters were lined up outside the Cook County Jail Wednesday night, upset over the possible release on bond of a man charged with striking and killing a 13-year-old boy riding his bike on the Southwest Side.

Protesters said Oscar Martinez Guerrero was set to be released on bond and walk out of jail. He is charged in the death of Isaac Martinez last weekend.
