Questions:
Was she in Austin the week before the murder?
Does she have a family member that lives in Austin?
Has anyone done a comparative analysis of the family members' gate, body types, and sizes vs the perp video?
Was the weapon actually a rock/mining tool?
Does she have a family member that owns a rock/cement construction company?
Looks like the company BB works for, Tucker Oil and Gas, makes specialty tools for pipelines. I really doubt the weapon is a specialty tool though. Looks like a normal ball peen hammer to me.
