I was on a ship, so heard a lot of this on CNN only...but I seem to recall that it was Clark's job to clean and maintain the mice cages etc...

Other glimmers...that his GF had been abused, and that he was a bit of a control freak.

A psychiatrist on CNN said that psychopaths know they are different, so they do their best to behave like everyone else...therefore, his buddies and others are stunned that their pal could ever do such a thing.

I bet his GF is less surprised.

Again, all this is just bits of stuff that leaked from the news reporting...who knows what really happened? Like, WHY????

RIP Annie Le.
