Why didn't anyone check the phone records and question everyone who called on the night of the murder.
The way it was showed is great though but meaningless on the part detectives carried out. If they questioned the killer and Kate's father about the phone records they would have got the meat and i hate to see an innocent person dead because of the poor judgment in every scenario. The role played by the cold case detective who found out the truth is good, the only think to talk about in this episode.
I just started liking this series and let me see how it goes.This has become one of my favorites serial to watch in free time.
