In September 2007, the Corinthos/Jacks nanny Leticia Juarez is the victim of a serial killer. In November, Nikolas Cassadine throws a Black and White Ball for his fiancée Emily Quartermaine, where both the killer and Anthony Zacchara wreak havoc. Emily is strangled to death by the newly dubbed Text Message Killer ("TMK"). In December, Georgie Jones is the next victim; afterwards her cousin Robin seeks comfort from ex-boyfriend Patrick, resulting in her pregnancy, the first HIV-related pregnancy for daytime. The TMK storyline carries on into 2008 as the killer hangs Cooper Barrett, then attacks and later kidnaps Sam McCall. It is revealed that presumed-dead Diego Alcazar is the killer, who accidentally hangs himself in the culminating confrontation.
