...the DA appears to have committed suicide by diving into a river.

This is the first time I've heard of this. Do you have more information? It throws another light on the reports we've gotten so far.

[Cicero]

That’s my guess. His computer hard drive was found in the river, near a town where he unexpectedly said he had to go for some reason. And he disappeared. His body has not been found.

Suicide is my guess because he is the logical person to have brought his hard drive there, presumably because there were things on it that he wanted to prevent any investigators from seeing.

[Campion]

We don't know that he committed suicide. Neither body nor suicide note was ever found, no murder scene was uncovered by forensics, nothing. His car was found, and his laptop was found in the river, but nothing could be recovered from it. He was involved in a couple of big drug investigations at the time, and had been running searches on his computer at home on "How to fry a hard drive" and "how to ruin a laptop".

It's a mystery.
