How did she get to Lake Ray Hubbard???
1. Her car? No, it was still at the apt.
2. A friend? Not sure, but it seems they would have come forward.
3. Public transportation? Highly unlikely, as many have already mentioned here. The distance is around 15 miles, and several connections would have to be made. Video cameras or someone would have seen her.
4. Uber or Lyft? Seems like that would be easy to find, since you summon them with a cellphone.
5. Stranger?
Any other possibilities out there? Again, Megan appeared to be an intelligent, serious, young woman, who was a hard working, reliable, type. She had a very low risk factor for being the victim of a violent crime, in a very safe city. This continues to puzzle me.
IMHO
