A judge looked at Rex Heuermann and asked if he was even a little bit sorry for the eight women he strangled to death. Heuermann barely answered. The judge called him a disgusting, despicable small man. Called him a coward. Then told the officers to get him out of his courtroom. The families chanted ogre as he was led away in handcuffs.

That was the end of Rex Heuermann’s sentencing. It was not the end of his usefulness. Before any of that happened, Heuermann agreed to something as part of his plea deal. He will sit down with the FBI’s Behavioral Analysis Unit and tell them everything — how he chose eight women, how he killed them, how he hid it for seventeen years while running a Manhattan architecture practice and raising a family in the suburbs.

His defense attorney says he is required to be truthful, accurate, and complete. The DA calls it a clinical exercise, not an investigative one. And here is the hard truth nobody in that courtroom wants to hear: Heuermann is going to enjoy every second of it. The attention. The importance. Being studied. Walking the FBI through his work like he is giving a lecture.

So why is the FBI doing it? What have fifty years of sitting across from killers actually produced? And what did Amanda Funderburg tell that courtroom about the phone call Heuermann made to her after he killed her sister?
