These killers fit two profiles

The more the victims scream and the more they beg for mercy, the more euphoric it feels for a psychosexual killer, experts said.

"It's the suffering of the victim that is important," said former FBI profiler Gregg McCrary, author of "The Unknown Darkness: Profiling the Predators Among Us."

"They want them to plead and beg for their life," McCrary said. "That's really what it's all about for them."

Nassau police described Evan B. Marshall, 31, of Glen Cove as a psychosexual killer after they said he decapitated and dismembered his neighbor Denice Fox, 57. Marshall was arrested and charged Friday with second-degree murder.

N.G. Berrill, a forensic psychologist and director of the New York Center for Neuro.psychology and Forensic Behavioral Science, said there are two types of psychosexual killers: those who commit repeated killings to satisfy sexual cravings and those who have a mental illness and may commit such a crime only once.

"The sadist has power issues. He savors the moment. They are individuals who enjoy frightening and torturing individuals," said Berrill, who evaluated serial killer Joel Rifkin of East Meadow, who confessed to killing 17 women.

"The psychotics are different," Berrill added. He said they are driven to hurt or kill by a delusional belief.
