For Warrick

The episode picks up immediately where it left off after Warrick was hunted down by an unknown suspect and shot him. Upon visiting Warrick to let him know he could keep his job, Undersheriff McKeen finds him in a pool of his own blood and calls for backup. As announcements are made over the radio, the CSIs react and head toward the scene. Grissom is first to arrive where he finds Warrick slumped over the wheel of his car and pulls him out to cradle his lifeless body.
When everyone arrives to the scene, Undersheriff McKeen goes over his statement. He was in the area when he heard the shots that came from a white male who took off running. McKeen went after the suspect, but only caught part of the license plate which is similar to Officer Pritchard’s plate. As painful as it is, the CSIs process the scene. Nick and Catherine examine Warrick’s car, Greg and David Phillips head straight to the lab, Det. Brass heads to the bullpen to give orders and Grissom follows Warrick’s body back to the coroner office. Catherine and Nick notice that Warrick had to roll down the passenger’s window in order for the suspect to shoot him causing them to believe that Warrrick knew the killer.
In a time of need, Sara returns. She meets with Grissom where she consoles him and the other CSIs as she offers to make funeral arrangements. Sara and Greg visit Warrick’s apartment where they find a DNA paternity test proving Warrick to be the father of Eli Brewster (Tina Brewster’s son) and a Psych Evaluation to win custody of Eli. Back at Warrick’s car, Catherine and Nick discover the gun that was left inside was stolen from evidence by Pritchard and knuckles prints on the window. Catherine and Nick also notice that Warrick had to roll down the passenger’s window in order for the suspect to shoot him causing them to believe that Warrrick knew the killer. When the CSIs recreate the crime scene, they determine that McKeen could not have heard the gunshots because of the club’s music that is located around the corner. This leaves McKeen as a suspect.
Meanwhile, McKeen proves the CSI’s theory right as he heads to the Whiskey Bend Motel where he and Pritchard have been hiding out. McKeen informs Pritchard that the CSIs discovered the gun that was used in a previous case handled by Pritchard. It’s obvious that neither of them can trust each other.
Back at the lab, the CSI’s are gunning for McKeen. They take the bullet case found in Warrick’s car and trace it for a finger print. The partial print matches McKeen. Being very delicate with the situation, they review his phone logs and find that he’s been staying at a hotel. When they arrive, they notice they had just missed McKeen and Pritchard. Brass calls McKeen and leads him to believe that everyone is on the look out for Pritchard, while Archie triangulates the call to determine exactly where he is located. Tension forms in the car between the two murders as Pritchard begins to understand that he is being used as McKeen’s scapegoat. Nick and Brass are just on their tail as Catherine and Grissom are close behind. Nick and Brass pull over to McKeen’s wrecked Cadillac and Pritchard’s dead body where Nick takes off searching for McKeen in the woods. Brass calls in for back up knowing what Nick is capable of. Nick finds McKeen where at first he tries to convince him that it was all Pritchard until finally he taunts Nick hoping he would just shoot him as he is already slowly dying from a previous gunshot wound. Brass, Grissom and Catherine meet up with Nick where they have the pleasure of arresting McKeen.
At Warrick’s funeral, Grissom gives the eulogy expressing his deepest remorse and remembers Warrick for who he was. Grissom also mentions Warrick’s son that he left behind and how he will know who and what his dad was through the CSIs.
