• The issue contained an article titled “Serial Killer Eyed in L.I. Slay,” which reported on the murders and disappearances of:
• Valerie Mack
• Jessica Taylor

DNA, including a hair found on a drape under Jessica Taylor‘s body, ties Heuermann to both murders, according to prosecutors.

• Ray Tierney Interview Transcript: Context: Post-plea interview following Rex Heuermann guilty pleas
• Opening: 
• Host: “A decades-long search for answers in the Gilgo Beach serial killer case is now over. Rex Heuermann pleaded guilty to murdering seven women and admitted to killing an eighth on Long Island. Joining us now exclusively to talk about what happened in court and what’s next, Suffolk County District Attorney Ray Tierney.”
• Plea Agreement
• Q: How did this plea deal come about?
• Tierney: “As a prosecutor, you just kind of forge ahead, and then at a certain point, quite recently, the defense informed us that the defendant wished to change his plea, and so that’s what we did.”
• Modus Operandi
• Q: What did you learn about these killings? Was it the same in every case?
• Tierney: “I think his modus operandi changed a little bit, evolved over time. Initially, he was dismembering the women and then dumping their bodies in different places, and then he went from just leaving them at Gilgo wrapped in a shroud.”
• Sexual Element
• Q: Did he have sex with them?
• Tierney: “We’re not sure. I tend to not think so, but the claim was that he did.”
• Victims and Families
• Q: How important was it to stand with the victims’ families?
• Tierney: “I think it was the most important thing. When you look at this, the notoriety, everyone is interested and intrigued, and they forget these are real women with real lives whose lives were tragically cut short. It was nice to give them some closure.”
• Investigation and Task Force
• Q: How was the case solved after so many years?
• Tierney: “We were fortunate to bring together a lot of really talented investigators from a lot of great organizations, the FBI, the State Police, the Suffolk County Sheriff, and the Suffolk County Police Department, and got help from a lot of other folks.”
• Evidence
• Q: What evidence cracked the case?
• Tierney: “There was the phone evidence, there was the DNA, there was the internet searches, there was the planning document that we found at his house. There were mementos, keepsakes commemorating these murders. So, a whole bunch of stuff.”
• Family Awareness
• Q: Did he speak to his family before the plea?
• Tierney: “I believe he did. I think they were informed.”
• Double Life
• Tierney: “He really lived a double life. He was the suburban dad next door who was also a serial killer, and he really was very disciplined in keeping those two lives extremely separate.”
• Phone Usage
• Tierney: “At most times, he had three phones on him. He had his phone for work, a phone he used to contact escorts, and another phone he was using to lure women in. We spoke to friends and family, and no one ever saw him with more than one phone. He was really disciplined in the way he hid this double life.”
• Motive
• Q: Did he say why he did it?
• Tierney: “No.
• Tierney (continued): “As part of his plea, the FBI Behavioral Sciences Unit are going to sit down and clinically speak with him and try to determine motivations, why he was compelled to do what he did.”
• FBI Behavioral Role
• Q: What will they try to get from him?
• Tierney: “It’s not going to be investigative; it’s going to be clinical. They’re going to try to gain insight into what drives someone to do these things, how we can learn from it, how we can mitigate it, and how we can catch the next individual.”
• Custody
• Q: What happens to him now?
• Tierney: “He’s in protective custody. Given the notoriety of the case and the nature of the crimes, those individuals typically don’t do well in a prison setting.”
• Wife
• Q: Why was his wife cleared?
• Tierney: “He was extremely disciplined. He maintained separate lives and concealed his activities effectively.”
• Other Victims
• Q: Do you think there are more victims?
• Tierney: “It doesn’t matter what I think. It matters what we can prove. We’re going to keep working, and we’ll go where the evidence leads us.”
• Tierney (continued): “After Amber Costello, he had been identified by witnesses, and that may have caused him to stop.”
• Evidence and Forensics
• “There was a Ramcharger from Pennsylvania that was associated with the Sandra Costilla case. State troopers took that from Pennsylvania, brought it to our lab.”
• “We recovered a Bounty paper towel off of the crime scene of Megan Waterman. They compared it to the same Bounty towel we recovered from the defendant’s home. They matched.”
• “This was a memento that we argued the defendant kept.”
• “The phone evidence, the financial evidence, the mementos, the planning document, and the DNA evidence… all of it is layered.”
• Sentencing and Next Steps
  • Tierney: “We have sentencing on June 17, and the resources that we’ve been using on this case will now be turned to other unsolved cases, with the hope of providing more closure for more families.
