A Sandusky man will serve 18 years in prison for shooting and killing an innocent bystander during his shootout with another man in Columbus last year. 29-year-old Rico Brown pleaded guilty to involuntary manslaughter and felonious assault charges in the death of Champaine Adkins. Prosecutors say the shootout with 25-year-old Rayshwan Penn followed an argument among a group of women outside the Belcher Apartments on the north side. Penn is serving and eight year sentence.
