UFC fighter Desmond Green was arrested for DUI manslaughter Tuesday after he allegedly caused a 5-car crash that killed 2 women back in August ... and officials claim he had alcohol and drugs in his system and cocaine in his vehicle.
29-year-old Green is facing multiple charges after he allegedly lost control of his 2011 Dodge Durango on I-75 and swerved into a semi truck on August 18.
So, why did it take so long to arrest Green? Officials say they conducted a massive investigation that took months to complete. And now they feel they have enough information to successfully prosecute Green.
