Long Island Serial Killer May Be an an Ex-Cop

Police are considering the possibility that the serial killer who has dumped at least eight bodies along a Long Island barrier beach may be an ex-cop or other law officer, law enforcement officials familiar with the case said.

The possibility that the killer could be a former law enforcement official or other person with knowledge of law enforcement techniques is being considered based on evidence that the suspect may understand investigators' procedures, they said.

Numerous people with possible links to the four slain women who have been identified have come to the attention of police since the investigation began, the officials said.
