The probe began last week when the 13-year-old girl darted from a couple of curious police investigators and ran for a Citico Street home.
It ended Tuesday in the same house when police found 74-year-old convicted sex offender Robert Grey Foxx dead on his couch, a plastic bag pulled snug over his head.
Police said Foxx committed suicide.
He had been arrested Dec. 21 after an investigation revealed he started two years ago paying an 11-year-old girl for oral sex at least twice a week.
Too bad the coward didn't do it BEFORE he starting molesting another child.
