Former Air Force star Dee Dowis' blood alcohol content was nearly three times the legal limit when he was killed in an automobile accident in suburban Atlanta on Aug. 29, according to a report obtained by the Colorado Springs Gazette on Tuesday.

Dowis, who set an NCAA career rushing record for quarterbacks and finished sixth in Heisman Trophy voting in 1989, had BAC levels of 0.21 and 0.233 in separate samples recorded by the Gwinnett County medical examiner. The 48-year-old Dowis was killed in a two-car accident on Interstate 85 around 5 a.m. ET.

The legal BAC limit is 0.08 percent.

Dowis lived in South Carolina and worked as a pharmaceutical salesman.

As a sophomore in 1987, Dowis took control of the Falcons' wishbone offense and never looked back. He rushed for 1,315 yards, an NCAA single-season record for quarterbacks that stood for 12 seasons. Dowis ran for 972 yards as a junior and also tied an NCAA record when he completed 11 consecutive passes against Northwestern.

As a senior in 1989, Dowis became the fifth player in NCAA history to run and pass for more than 1,000 yards in a season. He ran for 1,286 yards with 18 touchdowns and passed for 1,285 with seven scores. Dowis finished sixth in Heisman Trophy voting as a senior; Houston quarterback Andre Ware won the award.
