Well, happy belated anniversary, Deepwater Horizon disaster!

The Deepwater Horizon oil rig on fire in 2010. The rig's explosion caused the death of 11 people.

Just four days after the second anniversary of the Deepwater Horizon explosion and oil spill, the U.S. Department of Justice has filed criminal charges against a former BP engineer, Kurt Mix, for obstruction of justice.

USA Today reports that Mix is accused of deleting hundreds of text messages with a supervisor regarding failure in BP’s early attempts to cap the blown-out oil well on the floor of the Gulf of Mexico.

Mix’s messages indicated that BP’s early, public estimate of the oil flow — 5,000 barrels a day — was short by about 10,000 barrels per day. He faces 20 years in prison.

BP is cooperating with the investigation.
