Geraldine Hart

The hair came back as a match to Heuermann.

I mentioned the belt in the previous episode when Police Commissioner Geraldine Hart held a press conference about the murders and shared a picture of the initials on the belt.

At the time, investigators didn't know if the initials were HM or WH, depending on the orientation.

Um, now that it's linked to Heuermann, they were able to determine that the initials were likely WH for William, who was Heuermann's grandfather.

He credited the partnership between the police department, the district attorney's office, and the FBI.

He thanked his predecessor, Commissioner Geraldine Hart, for initiating the relationship with the FBI that made the genetic genealogy analysis possible, and he said something that cut through the formality of the press conference.

"I pray that nobody else has to go through this type of ordeal." Irene Wilkowitz had driven hours from Rhode Island to be there.

She walked into the press conference and for the first time in her life saw a photograph of Herbert Rice, the man who killed her sister.
