WNBA star Brittney Griner is pubically sharing some details about her harrowing experience during her time in a Russian prison. Griner sat down with ABC News' "Good Morning America" and fielded questions about her nearly 10-month detainment and imprisonment.

She was arrested in February 2022 after authorities found vape cartridges containing cannabis oil in her luggage at a Russian airport. 

"My life is over right here," Griner said as she recalled the moments after she realized the cartridges were in her bag.

Griner was detained and later transferred to a Russian penal colony roughly 300 miles outside of Moscow following a nine-year prison sentence.

In December 2022, Griner was released in a prisoner exchange for convicted Russian arms dealer Viktor Bout. ABC's "Good Morning America" shared a clip on Tuesday of the upcoming interview with Griner.

"I was just so scared," Griner said as she wiped away tears.

The wide-ranging interview is reportedly expected to cover Griner's entire ordeal from the time she was arrested to the time she was released.

The two-time Olympic gold medalist hinted that she battled suicidal thoughts, suggesting that she attempted to shift into survivor mode, but she also "didn’t think I could get through what I needed to get through."

Griner also said the living conditions inside the penal colony left her feeling "less than a human."

"The mattress had a huge blood stain on it. I had no soap, no toilet paper. That was the moment where I just felt less than a human," Griner noted as she reflected on her time behind bars.
