It's possible. But "quick thinking" in this scenario would be administering or calling for help, don't ya think? IMO.
What if EA's immigration status, the fact he was loaded (partially at least), and fear of messing up his parents, all rolled into one, caused him to make really bad decisions. There is a lot there actually.
In our right mind that's what most people would do, that is, call 911.
Just commenting but am on the fence if accident/cover up is or could be the true story.
At this juncture, one would think EA would tell (or try to claim) an accident.
Before he was arrested, I wondered if his rib and arm injuries were due to the fact that he did have an accident (without Christina in his car).
To me, it wouldn't be a stretch for him to wreck his car on his way home and have all that happen despite the fact Christina was missing.
Just very bad luck considering the circumstances after he found out Christina was missing.
Now, I believe, LE is certain CM was in EA's car.
