Law & Order: New Orleans

'"In New Orleans' war against crime, the Major Criminal Case Investigation Squad pursues and brings down the worst offenders, and works in coalition with the District Attorney's Office to prosecute them. This is one of their cases." ― The opening narration by Steven Zirnkilton. (Season 12-present)' Law & Order: New Orleans is an American police procedural and legal drama television series, adapted as a spin-off of the long-running crime drama Law & Order. Created and produced by Dick Wolf, the series premiered on NBC on September 23, 2011.

Set in New Orleans, LA, the series follows the same two-part approach as the original series, but like SVU and CI, also allows significant development for the series characters. In each episode, when a crime is committed, the victims are represented by two separate yet equally important groups: the New Orleans Police Department, where a team of elite detectives and their ranking captain investigate the crime, and the New Orleans District Attorney's Office, where the D.A. and his team of A.D.A.s conduct the people's case against the offenders in the trial, with D.A. Investigators often assisting the police in their investigations to make sure they run smoothly. In every episode, the first half hour focuses on the investigation by the detectives, followed by the second half the of episode focusing on the prosecution of the offenders by the assistant district attorneys.

Investigating the crimes are the N.O.P.D.'s Major Criminal Case Investigation Squad (MCCIS), who all report to their captain. It is their job to investigate the crime, collect evidence, interview witnesses and then, when the evidence points to a suspect or suspects, place the suspect(s) under arrest. The matter is then taken over by the prosecutors of the New Orleans District Attorney's office. They discuss deals, prepare the witnesses and evidence and conduct the people's case in the trial.

Both teams work with the Medical Examiners Office, Crime Lab and psychiatrists from both the police department and DA's office, and deliver it those that abuse it, Big Easy-style. In the style of the original Law & Order, episodes are often "ripped from the headlines" or loosely based on a real crime that received media attention. At times, a particular case could take an entire season’s length to be closed.

A spin-off, Hartman, focusing on popular recurring character Chloe Hartman, has premiered.

It's later revealed that the mother had a second child, a daughter, while in prison, and when found the girl is discovered to have not only been put into her mother custody, but also have cocaine in her system.

Her son discovered this, and killed her when she tried to silence him.

Despite the circumstances, an ambitious new D.A. looks to charge the boy as an adult to make an example out of him, leaving McCorrea and Shields to try to get the case taken to family court, since the boy was only trying to defend his sister from their twisted, messed up mother.

Zhao, Shepherd, and Shields are ambushed by shooters as they leave a bar, and are taken captive by a pair of prison escapee brothers, Robert and Seth Appel, who insist that they are innocent of the triple murder they were convicted off. The Appels take the women's cell phones and abandon them, though not before Zhao sends out an SOS to Parker, who alerts the others. With this the MCCIS puts a BOLO out on the women and the Appel brothers. As they steadily track them down, the brothers detail to the women how they were arrested for the murders of their sister Maggie, her husband, and his mother, due to having strongly opposed the former two's relationship and had done everything possible to wrecking it, to the point of having Maggie take out a restraining order on them.

When the MCCIS finally tracks them all down, Zhao persuades them to re-open the brothers' case. With the help of McCorrea, Fowler, Carcaterra, and Jindal, the rest of the MCCIS uncovers that the brothers did in fact have an alibi, though a less than noble one: they had beaten up a guy who had stolen money from their co-owned business. It's also discovered that an ex-boyfriend of Maggie's had been stalking her in the weeks prior to the homicides. After searching his home and finding the murder weapon, the man confesses that he killed Maggie's husband and mother-in-law to stop their interference, and when Maggie refused to submit to him, he killed her too out of rage.

In the end, the man is arrested, convicted, and sentenced to death, and Robert and Seth Appel are vindicated and released. The final scene ends with Captain Renko announcing he will soon return to Dallas and the Texas Rangers to stay near his still recovering son Richie, shocking the entire squad.

Reyes will take over as interm C.O. until a permenant replacement can be found. As this occurs, the MCCIS is called into the scene of the double homicide of a teenage boy and elderly woman (who was the co-head of a local community center), both shot to death. Parker and Queen discover that there is a possible witness, who might have recorded the incident. Upon looking for the teen, who is nicknamed Kodiak, they discover that he is the pre-teen son of an ex-girlfriend of Frease's. After the community center's second co-owner turns up murdered in his office, the detectives suspect the same shooter, and eventually manage to find and bust the man D-Silv, a local thug.

At trial, McCorrea and Shields push for the death penalty after D-Silv shows no remorse, admitting he killed the teen boy for "looking at him wrong", and the woman and her co-worker for "getting in his way". Unfortunately, the confession is rendered inadmissable at trial, and the only evidence that can convict is the still-missing footage of the killing that Kodiak has stashed away. But Kodiak, out of fear for his and his mother's lives, refuses to tell the location of the footage, leaving Carcaterra and Jindal to work with the MCCIS to find it themselves. After no luck, and with D-Silv about to be set free, Renko and Frease makes one last push to do the right thing, rationalizing that D-Silv will kill him and his mother as soon as the charges are dropped and even bring his mother to persuade him to stand up to the thug. With that, Kodiak hands over the footage of the first two murders, which allow D-Silv to eventually be convicted of all three and sentenced to life without parole.

The episode ends with Renko emptying his office and saying goodbye to the squad as he returns to Texas.
