'But, they found Stephanie's purse was in there, [her]cane was in there. [The] TV was left on, [the] computer was left on. It was just very suspicious for them to be gone,' she told CBS News. 

Another friend of the couple, Tammie Wilkerson noted that there was 'no way' the couple walked away from their car and left their stuff behind. 

'There's no way that Stephanie or Dan could have walked away from that car. She has a cane. It was at home, her purse, their cellphones - things they would never have left at home. 

'They're very sweet people. There's not a mean bone in their body at all, which makes this very confusing,' she said.
