In a statement issued Thursday evening by Capt. Cliff Argyle, police said the bike is similar to Cleverley's, but it cannot be positively identified as her bike at this time.

"This bicycle was stolen from the Bridal Veil Falls area in Provo Canyon on Saturday night. After seeing news coverage of Camille and images of the missing bike, those involved came forward and have provided this bicycle to police," Argyle's statement said.

Robert Grossman, the Cleverley family's new spokesman, said the family is awaiting further confirmation and considers the finding speculation.

Earlier, police officials said they are fully committed to finding Cleverley and have not ruled out any possibilities in her disappearance.

Police Chief Craig Geslison told reporters that other criminal investigations have taken a back seat to the effort to find Cleverley, who has been missing since Aug. 30. The department is also working with the FBI, Utah Department of Public Safety, Utah County Sheriff's Office and University Police to find Cleverley.

"We have a daughter, a sister, a friend who is missing. We have a community that cares," Geslison said, his voice slightly breaking with emotion.

The investigation has involved a search of Provo Canyon, the shores of Utah Lake and the foothills, as well as interviews with registered sex offenders and anyone with a connection to Cleverley. Geslison said the FBI has provided assistance as well, with up to eight agents working the case and providing expertise in searching for a missing person.

The family also announced that a new, intense three-day search is being launched today, spearheaded by the Provo and BYU campus police departments. Grossman said the search will begin at 8 a.m., with searchers meeting at BYU's Harman Conference Center.

A statement from the family released on Thursday night said the Texas-based Laura Recovery Center, a group that works with police to help recover missing children, is joining the effort.

David Cleverley, Cleverley's brother, expressed his family's love for her, and made a plea to whomever may have her to let her go.

"We love her dearly and would like her to be safe," David Cleverley said.

Cleverley was reported missing after leaving her Provo apartment at noon Aug. 30. Argyle, who is leading the investigation, said she was last seen between 5 and 6 p.m. Aug. 30, riding her silver and lavender Schwinn bike north on 900 East near the LDS Church's Missionary Training Center. Argyle said the witness was a co-worker of Cleverley's who was so sure it was her he almost turned around to try to talk to her.

It is about 10 miles from where Cleverley was last seen to Bridal Veil Falls.

Argyle said Cleverley's debit card and personal identification number were used at a Crest store in Provo on Aug. 31 to purchase fruit juice and doughnuts. Argyle said the store clerk said it was a woman who bought the food, but could not positively identify her as Cleverley.

On Wednesday, police scoured the Clean Getaway car wash in Provo for clues to the case based on a tip. Argyle said they found nothing to help the investigation.

Police have also interviewed 40 people whose names they found in Cleverley's notebooks, Argyle said. He noted that there were some "persons of interest," but nobody who rose to the level of a suspect.

"Anyone is interesting to us if they have had contact with Camille," Argyle said. "I will not use the term 'suspect.' "

One of those interviewed was David Sperry, Cleverley's boyfriend. Dick Sperry, Sperry's father, said the police "raked him over the coals" during the questioning, but said it was understandable from the police department's perspective. Sperry said his son is innocent, since Sperry said his son, who has been dating Cleverley for almost five months, cares for her deeply and was one of the first to sound the alarm when she didn't return home. He said David Sperry has been helping with the search effort.

"She's like a daughter to us," Sperry said.

Capt. David Bolda, who is coordinating the search efforts, said the Utah County Sheriff's Office provided an airplane, as well as a search and rescue team and a horse unit to search the canyons and lake shore for Cleverley. Bolda said the Utah Department of Public Safety provided a helicopter. He said volunteers have also combed the Provo River Trail.

J. Callas and Jack Rhodes of Wolfridge Development Group in Provo also provided a helicopter for the search.

"I've always offered the use of the resources I have to law enforcement," Callas said.
