JBC is a serial offender who seems to get caught quickly after committing crimes. If you look at his prior convictions he is not the sharpest tool in the shed. BG is very cunning and after 4 years and 3 months I don't think LE is any closer to catching him. If BG gets caught it will be a fluke or he will make a mistake in the future that will tie him back to the Abby and Libby crimes by DNA. If there is no DNA this case will never be solved.
MOO JBC is caught for about 1 in 10 of his crimes. The ones he gets caught for look like when he is impaired.
