Jenni Rivera Plane Crash -- DEA Investigating Company That Owned the Plane

The company that owned the plane that crashed and killed Latin music star Jenni Rivera is under investigation by the U.S. Drug Enforcement Administration, who seized two other planes owned by the company earlier this year.

The planes were seized from Starwood Management in Texas and Arizona, but the DEA gave no more details.

Christian Esquino, who runs Starwood, told The AP yesterday that the DEA has been investigating him for more than 20 years ... but has yet to prove a single drug-related charge.

While that is true, Esquino was indicted on drug charges in the 1990s and eventually pled guilty to conspiring to conceal money from the IRS and was sentenced to five years in prison. He only served about five months.

Esquino said Rivera was considering buying the plane from Starwood for $250,000 and the flight was offered as a test ride.

Rivera and six others died when the plane crashed in Mexico early Sunday morning.
