The lead suspect in the sex-assault murder of Imette St. Guillen is also suspected of having committed other rapes

Murray Weiss:

The cops' focus on Darryl Littlejohn in the sex attacks surfaced after one victim watched the past day's TV footage of investigators searching the bouncer's blue minivan parked in his driveway — and phoned police to tell them it appeared to be the vehicle in which she was raped, sources said.

The woman was attacked in Queens late last year, part of an apparent pattern of at least three rapes in which the victims all gave similar descriptions of their attacker. A second rape also occurred in Queens, and the third took place in Nassau County, the sources said.

Littlejohn, 41, was moved to Rikers Island yesterday to await a hearing on whether he would be returned to prison for violating his parole on an armed-robbery rap.

As an ex-con, he wasn't supposed to be working security at The Falls bar in SoHo, where he was reported last seen tossing out a drunken St. Guillen early Feb. 25. Her body was found hours later in weeds off the Belt Parkway in Brooklyn.

Littlejohn has maintained his innocence in St. Guillen's slaying.

Investigators yesterday continued combing the hardened criminal's Queens home for clues as they try to build a case against him. Their latest haul included bags marked with blaring orange "Biohazard" stickers and stuffed with such items as military green pants, a black wool hat and Timberland boots.

They also towed away the minivan in Littlejohn's driveway — a dark-blue Dodge Ram 250.

In addition to that van, probers focused on his Ford Windstar, parked two blocks from the house, which matches a description of a vehicle spotted near where St. Guillen's body was dumped.

The van was missing a row of seats, and cops yesterday removed a similar row of seats from Littlejohn's house.

While Littlejohn insists he was nowhere near the remote street in East New York where St. Guillen's body was found, police say cellphone records put him nearby shortly before her corpse was discovered.

Sources say at least one of the calls from his cellphone was made to a girlfriend, who later told cops the conversation was inconsequential.

An apparent ladies' man, Littlejohn's personal phone book was filled with women's numbers — including ones for "Babymomma 1" and "Babymomma 2," the sources said.

But one neighbor said he could be abusive with his women, claiming that he openly hit one girlfriend in front of his home about two months ago.

"I saw him slap her. He hit her, and she fell onto the door," said the 28-year-old woman who spoke on condition of anonymity. "He's very intimidating. The way he walks, like it's all about him. I didn't like his aura."

His chilling words: 'You seemed like a real nice lady'
