Firm continues search for worker after oil rig fire in Gulf

Two remained in critical condition and one in serious condition, doctors said.

Three dive boats are now working around the burned platform and Plaquemines Parish sheriff's deputies are checking beaches, Black Elk Energy of Houston said in a statement emailed Sunday evening.

It said all helicopter companies flying in the area have been asked to keep an eye out, and a search-and-rescue dog will be brought to the platform Monday.
