BP rig could be designated as 'crime scene'
The wreckage of BP's ruptured Gulf of Mexico oil rig will be the focus of a massive investigation as authorities begin gathering evidence from what could amount to a crime scene at the bottom of the sea.
The Deepwater Horizon rig's failed blowout preventer and the twisted remnants of the drilling platform may be "exhibit A" in the effort to establish who is responsible for the biggest peacetime oil spill in history, with the companies under investigation in charge of recovering the evidence.
