Denise Huskins' Boyfriend's Attorney Says He Received Email From Her Abductors

— -- The alleged kidnappers of a California woman sent an email detailing their motive to the office of her boyfriend's attorney, he said Friday, saying it proves her disappearance was real and not a hoax as police have claimed.

Aaron Quinn's attorney Dan Russo declined to specify what was said in the six-page email that he claimed detailed the kidnappers' motivation for abducting Denise Huskins on Monday morning.

"These people are real," he told ABC News. "They're really motivated."

Police in Vallejo, California, said Wednesday that they found "no evidence to support the claims" that Huskins was abducted from Quinn's home before she was found alive two days later more than 400 miles away in Huntington Beach, California. They declined to comment on Russo's claims about the email his office received.

Huskins, 29, and Quinn, 30, have denied any involvement in a hoax through their attorneys. Russo has said that Quinn was tied up and drugged by at least two assailants the day his girlfriend was taken, which he said explains why Quinn was unable to call police until hours later.

Police said that Quinn told investigators that Huskins' abductors made a $8,500 ransom demand.

Both police and the San Francisco Chronicle said Wednesday that they received emails allegedly from Huskins' kidnappers. While police declined to detail the specifics of the email, the newspaper reported it received an email the day before from an "anonymous person claiming to be holding Denise Huskins."

The newspaper reported on Thursday that it received a second email from a person claiming to be one of the kidnappers that said the abduction was real.
