A Louisiana sheriff says three people remain in critical condition, including two in a burn unit, after an explosion at an oil rig on Lake Ponchartrain.
At a news conference this morning, Jefferson Parish Sheriff Joe Lopinto said a fire on the Clovelly Oil Co. rig was still burning.
Authorities expected the blaze to eventually burn itself out. One person remained missing after the blast and U.S. Coast Guard crews were searching for him.

The search has been complicated by 4 foot to 5-foot seas and stiff winds, Lopinto says. A total of seven people were hurt. Authorities say four of them have been released from hospitals.
