Westchester co-ed missing

A co-ed from Westchester mysteriously vanished while walking home from a bar at her Midwest college, and cops say they suspect foul play.

“It’s every parent’s nightmare,” said distraught dad Robert Spierer, of Scarsdale, whose daughter Lauren, 20, hasn’t been seen or heard from since early Friday.

Lauren Spierer — a promising, petite, Indiana University sophomore — was last seen walking barefoot alone from a friend’s Bloomington, Ind., apartment around 4:30 a.m. after a night of partying at Kilroy’s, a local sports-and-beach-themed bar, police said.

Cops said surveillance video from Lauren’s apartment complex less than three blocks away shows she never made it home. Her keys were found a block away from where she was last seen.

“We certainly think there could be foul play,” said Bloomington Police Lt. Bill Parker, as nearby woods and Dumpsters were searched for any sign of the missing blonde.

Her family made an impassioned plea for the public’s help. At just 4-foot-11 and 100 pounds, Lauren has a heart defect that can cause dangerous arrhythmias and requires medication.

“It’s important that we get a hold of her . . . as soon as possible,” said Robert Spierer, a top New York tax accountant who rushed to Indiana on Saturday with his wife, Charlene, after a friend of their daughter’s called to say she was missing.

Lauren, an apparel and merchandising major, is slated to start an internship at a Manhattan Anthropologie store later this summer.

Born and raised on Manhattan’s Upper West Side before moving to Westchester with her close-knit family, which includes her older sister, Rebecca, Lauren graduated from Edgemont HS and is known for being smart and intuitive.

“She’s brilliant,” Rebecca Lefkowitz, a close friend since seventh grade, told The Post yesterday. “She would never put herself in a dangerous situation.

“We’re all hoping and praying. We know she’ll come home, and we won’t leave any stone unturned” in trying to find her.

Dozens of volunteers — including Indiana University head basketball coach Tom Crean — joined the Spierer family and police in searching for her.

A Twitter page, @NewsOnLaurenS, had more than 3,200 followers by yesterday, and a Facebook page about Lauren’s disappearance had 4,000 members.

“I need her to be found,” Blair Wallach, Lauren’s IU roommate and childhood campmate, told The Post at her home in Closter, NJ, before breaking down in tears.
