Never watched CSI?
I'm a 'Johnny Come Lately', so I apologize for rehashing something from the first two episodes.
The first thing I thought when they killed McCann was, 'Now what, 'knock him out in his shower' to explain the drowning?' I knew once they did the autopsy, this would come up, especially with the dump site in the river.
So, having seen this revelation, I'm now wondering how they're going to explain it, after they supposedly saw him exit his house and get in his car.
No spoilers, thanks, guess I'll have to keep watching for the be 'denouement.'
BOHICA America!
