NEW ORLEANS (AP) – A BP rig supervisor said Wednesday that he is innocent of manslaughter in the deaths of 11 workers in the 2010 explosion on the Deepwater Horizon offshore drilling rig that started the spill disaster in the Gulf of Mexico.

“I think about the tragedy of the Deepwater Horizon every day,” Robert Kaluza told reporters just before his arraignment. “But I did not cause this tragedy. I am innocent and I put my trust, reputation and future in the hands of the judge and the jury.”
