Hyogo Prefectural Police rearrested a 45-year-old man Wednesday on suspicions he murdered a 7-year-old girl in 2007 after he admitted his involvement during voluntary questioning in May this year.
The 17-year-old unsolved case now appears to be heading toward a major breakthrough.
The suspect, Kunihiko Katsuta, is serving an indefinite prison sentence for the 2004 murder of another girl in Okayama Prefecture.
