BBM. I obviously don't think her role was only providing an alibi, hence me saying she was much more directly involved once FD returned to Farmington. Her DNA is found in multiple places in the trash recovered from Albany.
Even if MT did plan her morning to try and provide an alibi for FD and that was her only role, that is still enough to be charged with conspiracy to commit murder though.
I agree that the wording of the AW is interesting. They do use the word "claims" before her alibis for that morning. The three different alibis she provides, however, are easy to either confirm or disprove. This warrant was months in the making. If they had proven that MT wasn't at ANY of those locations, I would think it would be included.
There is always the possibility that someone else had MT's phone during the morning, drove to the three places she mentioned, and MT convinced two friends to lie for her (since she supposedly saw them in person), but it's a lot to orchestrate. The specificity of her claims and the ease with which they could be verified seems VERY intentional to me.
