"He's going to continue to kill because they don't stop," says Vernon Geberth, a former NYPD homicide lieutenant and author of Practical Homicide, a textbook used in police academies around the world. "Now he's got to come up with a new plan, a new location. Psychologically this is stressful for him because that was a place he would go to relive the event, act out scenarios, therefore relieving stress."
In December, a cop on a training exercise found the remains of four women off Ocean Parkway in Gilgo Beach, N.Y. After the women were identified, searchers began looking for Shannan Gilbert, 24, who went missing in May and was last seen running out of a house in Gilgo Beach.
Then on Monday, in nearby Nassau County, authorities uncovered in brambles off Ocean Parkway what they believe to be two more sets of human remains, including a skull, says Nassau County Lt. Kevin Smith.
Another Grim Discovery"We were hoping we would not find anything," says Smith. "No one wants to see another homicide was committed. The bottom line is we did and now that we have, we and the state police are conducting our own homicide investigation."
Only the first four cases have been linked to each other so far.
Some have speculated the killer has ties to law enforcement since he used disposable cell phones from crowded places to place taunting calls to the sister of one of the victims. But Smith says police are not focusing in that theory.
"We're not looking to prejudice the case," says Smith. "If anyone thinks they know someone who is suspicious, we want them to contact us."
Geberth doesn't buy the law enforcement angle either, simply because anyone can gather basic crime investigation techniques from watching TV, but does think the killer is a local.
He's also "highly organized," Geberth says. "He plans these things out. He had a disposal site. He had a reason to be there in case someone did spot him. This is a high functioning individual."
