Denver media reported the winning bid Tuesday came from a man identified only as John. In all, the event, dubbed "Mollypalooza," raised $38,000 help Molly Bloom's family with medical expenses, organizers told the television stations and the Rocky Mountain News.
Bloom lost a leg and part of her pelvis in the May 13 accident and was undergoing rehabilitation at a Denver hospital.
"(Biel) has this opportunity to create a buzz that would provide some support and she's more than happy to do that," Jonathan Biel, Biel's father, told KMGH-TV. He said it was his daughter's idea to hold the auction for a lunch date.
The young man with close-cropped hair topped another young man's bid of $23,500, the Rocky Mountain News reported. He wore a dark, striped suit and a white tie.
"I'm a senior vice president for an oil and gas company in Denver," the News quoted him as saying after he was brought up to the stage.
Biel, a Boulder native who was on location in Italy, wasn't at the fundraiser Tuesday, but taped an audio message in which she said: "I promise, I'm a cheap date." The lunch date will happen Aug. 18 when Biel is in town to receive a humanitarian award, organizers told the stations.
Organizer contact Jeanne Lee did not immediately return phone or e-mail messages left by The Associated Press.
Bloom was run over and dragged about 38 feet by a Hummer stretch limousine, police said. Limousine driver Stanley D. Sample, 38, faces a misdemeanor charge of careless driving resulting in serious bodily injury.
