Dr. Brett Morton is a psychiatrist whose son was kidnapped and murdered by his thirteen-year-old neighbor, Jake O'Hara.
Brett wrote papers on the subject of child sociopathy. In these papers, he cited that their condition cannot be cured and measures should be taken to prevent these children from committing inevitable acts of violence.
During Jake's trial, Brett initially requests leniency for him, but after information comes to light that he has psychopathic tendencies and that he will be released from prison by the time he is eighteen, Brett regrets his decision and shoots Jake in the courthouse. He then uses his expertise as a psychiatrist to try and convince the court he had post-traumatic stress disorder at the time. When he takes the stand, he tells the jury that he has no memory of killing Jake but later admits he did kill him post-trial. He was subsequently acquitted of the murder.
After leaving the courthouse, Brett confesses to Stabler and Novak that he was guilty over his request for leniency for Jake, that he feared he would kill again after his release, and that he planned to shoot Jake in the courthouse after he found out he was a sociopath. He looked around, saw the court officer's gun and waited for the right moment to take it to kill Jake. Stabler and Novak confront him for his "manipulation" towards the court, like Jake. Brett agrees, but points out one thing that distinguished him from Jake: that he would have continued killing while the psychiatrist himself will never kill again. (SVU: "Conscience")
