FBI agent testifies at ex-BP engineer's trial

NEW ORLEANS (AP) — An FBI agent has testified that some of the text messages that a former BP engineer deleted from his cellphone contained information that could have been evidence in the Justice Department's investigation of the company's 2010 oil spill in the Gulf of Mexico.

Special Agent Kelly Bryson was the first witness to testify when prosecutors began presenting their case Wednesday for Kurt Mix's trial on obstruction of justice charges.

Investigators recovered a string of deleted messages that Mix had sent to a supervisor while he worked on a team of experts who were trying to seal BP's blown-out Macondo well.

Bryson said some of those messages helped show what BP engineers knew at the time about the amount of oil gushing out of the well.
