This season is full of new stories. Tonight's episode brings to a close a case that haunted Jo all the way from DCPD. I was guessing the whole time who did it. It was a bit obvious from the start that the senator had something to do with the witness but the appearance of Jo's former partner made me doubt it for a second... good he wasn't there to kill anyone... it's sad that out of a father's desperation to put the rapist behind bars, he resorted to fabricating a witness that ended with a murder. And again, the desperation of the rapist to get out of a murder ended up being killed! whew!
