When Norwood was found by a store employee opening up the next morning, police say the position she was tied in, with her hands bound above her head, was suspicious to police, suggesting she might have fastened the bonds herself.
Murray's car had also been moved, and was spattered with the blood of Norwood, who police say told them her assailants ordered her to re-park the car, which had been outside the store, and return in 10 minutes or be killed.
"As we began analyzing the physical evidence and looked at the medical reports, it was not supporting what Ms. Norwood had told us," Manger said.
Then workers at the Apple Computer store next door told police that on the night of the killing, they heard two women arguing.
A college teammate of Norwood shed some light on her past.
"Other girls on the team told me things like, 'Watch your locker, keep it locked.' She's been known to steal things," Megan Healy said.
The family of Jayna Murray is healing through launching a foundation to remember the adventure-seeking young woman who loved to go bungee jumping.
"One of the most fearless people I've ever known in my life and that's as objective as a father can get. I really admired her for everything she did and everything she represented," David Murray said.
The family has created the Jayna Troxel Murray Foundation to remember Murray's life.
"People have always commented that it was her smile and it was her hugs. Whether she knew you for two seconds or years, those were her greetings. She wanted people tot feel comfortable and happy," Phyllis Murray said.
