Exclusive: Erin Andrews Helped Crack Case With Her Jeans

Oct. 5, 2009 — -- Erin Andrews' own detective work was integral in helping investigators track and arrest her suspected stalker, Andrews' attorney said today.

With the help of her stylist, Andrews, the ESPN reporter who was secretly filmed in the nude in her hotel room on multiple occasions, was able to identify the "exact room, the exact date and the exact location" where one of the videos was made, based on her blue jeans visible in the video, attorney Marshall Grossman told "Good Morning America" in an exclusive interview.

"I've since learned that women know what they wear on [any] occasion," Grossman said with a smile.

That detailed information helped investigators identify Michael David Barrett, a 47-year-old divorced father, as the alleged stalker, based on hotel records.

Andrews' direct involvement in the case may be only the beginning, because she is "hellbent" on testifying against Barrett and will be working with authorities and lawmakers to toughen stalking laws, Grossman said.

"Originally, Erin was quite relieved with news of the arrest," he said.

But after Andrews reviewed investigators' reports and the enormity of the alleged crime was revealed, Grossman said, her anxiety has increased.

Barrett is expected in court today for a transfer hearing after his arrest Friday at Chicago's O'Hare International Airport.

Barrett is accused of making nude videos of Andrews by filming her with a cell phone camera through an altered peephole in the door of her hotel room. Authorities believe Barrett initially tried to sell the videos to celebrity Web site TMZ and then posted one of them on the Internet in July.
