Tori Bowie, a three-time Olympic medalist and world champion sprinter, died last month due to complications from childbirth, medical officials said Monday.

Bowie, 32, was found dead at her home in Orlando, Florida, in May, shocking fellow athletes and the broader track and field community.

An autopsy report obtained by USA Today found Bowie was eight months pregnant when she died in the process of giving birth. Possible complications included respiratory distress and eclampsia , a rare but serious complication of preeclampsia, when a person develops seizures during pregnancy.

The local medical examiner linked her death to natural causes.

Its unclear if her family and friends knew she was pregnant at the time of her death, The Guardian reported .

Bowie, a native of Mississippi, was a celebrated athlete and won three Olympic medals at the 2016 Games in Rio de Janeiro. Her home state honored her after her remarkable performance, declaring Nov. 25 Tori Bowie Day, a designation the athlete called humbling and something she never thought would happen.

She later won two gold medals at the 2017 World Championships in London.

Her last competition appearance was in 2022.
