The Starkville Daily News reports that Poole will serve 20 years in prison.
Poole was sentenced to 25 years with five years suspended on one count. Poole was sentenced to five years on each of the other counts to run concurrent with the first count.
Authorities say 19-year-old Treasure K. Huffman was pronounced dead at the scene after Poole's SUV crashed on a county road.
Authorities say others in the car told investigators that the group had been drinking before deciding to go for a ride and the group got Poole to drive rather than Huffman, who was a designated driver.
