NEW ORLEANS (AP) — The Coast Guard says a series of “sheen sightings” have been reported in the area where the Deepwater Horizon drilling rig exploded in the Gulf of Mexico last year, but BP’s capped well isn’t the suspected source.
 
A statement issued Tuesday by the Coast Guard says the sheens could have come from the sunken rig’s riser pipe or from other underwater debris. The Coast Guard says recent video footage shows no evidence of a leak from the blown-out well that was capped last year.
