At first I thought it must be the Homeland Security guy, but I'm fairly certain he's a Red Herring. Who is Red John?!
Also, Lorelei didn't break out of prison, the FBI (or someone in the FBI) secretly moved her to a different prison and kept it all secret from the CBI. That's why Jane's been spending all this time over the last few episodes trying to get her back from the FBI - there'd be absolutely no point if Red John got her out, because she'd either be long gone or dead.
