It's already been said on the news that her friends wanted her to join them at Mel's. They texted her at Brettly's but they had already gotten Taco Bell. I guarantee you she went there a good bit. All that young crowd does - it's the only good food open late except fast food. Also, I've been there with acquaintances of her crowd.
But let me shoot my own theory down. If she had decided to change her mind and go to Mel's, see someone, and get a ride home, she would have texted someone there and told them so. But that's going out of her way to get a ride for the last 1/3 of the distance. Plus, she already just saw them at Artmosphere.
So... no.... sorry for wasting y'all's time!
Mel's Diner is about half way home. It's 2 miles from Ryan and a half mile from the Coliseum. This actually makes more sense as to why she would take that route. If she was in contact with her friends and thought they were there, she could have gotten on her bike and decided while riding to make a pass there. She wouldn't have stopped to text them. And maybe her intent was to visit with them. If they were still there, then great. If not, she was on her way home anyway.
Does anyone know if they've checked surveillance cameras down that far?
