A Rockford man linked three years ago by DNA tests to a 1988 slaying of a teenager is convicted of first-degree murder for the crime.
The Winnebago County jury deliberated less than three hours before finding 44-year-old Donald Johnson guilty in the slaying of 15-year-old Rebecca Lynn Smith.
The girl's body was discovered in a creek bed a day after she left home for a soda and didn't return. She had been raped and strangled.
The case went unsolved until 2001 when authorities announced they had found the girl's suspected killer. Johnson was serving a 60-year prison sentence for a rape and had submitted his DNA to a state run database.
Tests revealed his DNA matched evidence found during the investigation of the teenager's death
