A former Halliburton manager pleaded guilty Tuesday to destroying evidence in the aftermath of the deadly rig explosion that spawned BP's massive 2010 oil spill in the Gulf of Mexico.

Anthony Badalamenti, 62, of Katy, Texas, faces a maximum sentence of a year in prison and a $100,000 fine after his guilty plea in US district court to one misdemeanor count of destruction of evidence. His sentencing by US district judge Jay Zainey is set for 21 January.
