"which I personally suspect"
why? what else do we know about him? (i'm curious, i know nothing of the case)
From what I've heard thus far, he's the prime suspect--several things about the case that have already been made public stand out, especially given that I'm actually studying these things.
There apparently was some bad blood between Hans and Nina--ever since they started to break up in May 2004.
She was last seen at his house dropping the kids off. Never showed up for a meeting with her best friend.
Police have found a link to the found car and then successfully used it to obtain a warrant for Reiser's DNA.
