I too wondered about Youngblood. I have Googled read all the trash from the tabloids. Tablouds same useless crap. Tim is if you paid attention a single father of 4. At the time of the episode where Tim returns to the show only one of his children were school aged. He simply is running his own bail bonds business from home. He is home with his children simple as that.

Not to mention that fact that Dog probably doesn't want to be associated on TV with a guy who is tuggin' it in parks, blowin' loads all over slides, and then kicking some Security dudes ass, probably with his weiner still out, which makes Tim totally gay. I'm suprised he isn't being charged for attempted rape too, lol.

Most of the people on here have it wrong. Tim IS his former partner on the show. The show is being filmed more in Colorado when before it was all about Hawaii with the occasional trip to CO.
Tim Chapman has always had his own Bail-Bonds company but teamed up with Dog for the show. They are still cool with eachother just not working together this season. Tim didn't want to leave his family for all that time they were filming. That is pretty much the whole scoop.

thats crazy that he would ruin his career doing something like that

No he's not! You're joking, right?
Edit: Oh my gosh, I just looked it up, it's true. The article said Tim is separated from his wife, too.

He is charged with masturbating in public and attempted murder of the security guard that caught him in a park.

he wasnt on tonite, Lyssa has taken his role

oh wow i didnt know he wasnt with dog anymore,wont be the same without Tim..

I am not sure but I do know that Tim is having other type of legal problems so that could be why they are former partners.
