TUCSON (KGUN9-TV) - 9OYS first spoke to Alicia Stardevant five days into the search for Isabel.
"Do you remember anything bizarre from that night?" asked 9OYS reporter Marcelino Benito. "Yeah, well at 6:30 in the morning, my dogs were barking, their dogs were going nuts," replied Stardevant.
Stardevant's bedroom window was just 10 feet away from Isabel's bedroom window. Almost two years later, she still remembers what more she heard outside.
"I noticed voices outside my bedroom window," said Stardevant. "Noticed they were males and multiple."
Overnight, that critical recollection made national news. Stardevant was interviewed by the networks and HLN's Nancy Grace who called her a "earwitness to a possible abduction of a 6-year-old child."
Flash forward to today and Isabel is still missing, and Stardevant is more convinced than ever.
"I really feel those voices I heard were the ones who took her," said Stardevant.
She now lives in Colorado, but does follow news of the case. TPD's revamped investigation in her old neighborhood rekindled a regret she's struggled with since that morning.
"My heart kind of hurts honestly," said Stardevant. "It's such an easy thing. My window was just two feet from my bed. I could have looked. It's really hard. It could have helped case tremendously if I would have just opened my blinds."
She says if she had, then just maybe, she'd have the answer all of Tucson and the world is searching for. Who took Isabel? Where is she? Questions she can't help but think about when she see's Isabel's smiling face.
"I just feel so bad for her," said Stardevant. "Whatever happened she had nothing to do with it."
Stardevant's recollection, like so many other leads, led nowhere. It's why TPD revamped its investigation last week. Tucson Police says it has worked. The door-to-door effort has generated several new tips. They are currently reviewing those tips for potential new leads.
