Soon after Jed McCaleb sold Mt. Gox the price of Bitcoin dropped from around $15 to $0.01 in an hour. Also, 80,000 bitcoin were missing at the time of the sale without the buyer (Mark Karples) knowing. There was a lot of weird language in the contract to protect Jed. When the hack happened, investigators believed the infiltration happened through Jed McCalebs administrative account. Here is a link that explains what happened in better detail than what I can provide.

It was some shady stuff and makes me a little unsure whether or not I trust ripple.
