Earlier today a false report said Jo was going to be arrested. There has been no update saying Jo has been arrested. He lives in Antioch, TN where Misty's grandmother, Flora Hollers lives.
LE knew Jo was at Ron's on Monday and took the van from Timmy's late Monday evening and damaged the van. LE examined the van. Misty said she didn't trust Joe and wasn't sure if he was involved and Hank Sr told LE he felt Joe was involved from the very beginning. LE went to TN to talk to Joe several times and LE never named him as a suspect. NG is pointing the finger at Misty and Tommy blaming them for hindering the investigation but IMO, LE are the ones who deserve to be blamed. In any event, even if her body isn't recovered, it looks like there will be a trial.
