From all that I read about how Sr. was found, it doesn't appear he ever meant to kill himself the first time but rather stage the scene to fit his agenda.
I also don't think he was living it up in LV as it appears without a care in the world. Just a hunch, but I'll be he knew his days were numbered. He'd be really stupid if he didn't think LE was watching him after the first arrest.
Stupid or arrogant, maybe one in the same.
Let's all hope the next news bulletin is they have found little Ara.
