Keith Jesperson, the “Happy Face” serial killer, is warning fellow inmate Rex Heuermann may be treated harshly when he is housed in prison ahead of his upcoming sentencing in the Gilgo Beach case. The warning comes from letters Jesperson has exchanged with Heuermann while both are incarcerated. In those communications, Jesperson suggests Heuermann could be “tossed to the wolves,” implying increased risk or hostility from other prisoners. Multiple outlets report that the letters also hint at the possibility that Heuermann could have additional victims beyond those alleged in the Gilgo Beach investigation, though the reports describe these claims as coming from Jesperson’s correspondence rather than new court findings. Fox News and the New York Post frame the message as part of the lead-up to Heuermann’s June 17 sentencing date, while Yahoo News presents a similar account of Jesperson’s warning. The reports do not indicate that any new charges or confirmed facts have been released as a result of the letters.
