Retired US Col. Steve Gabavics went public Monday with an account he had previously only spoken about anonymously—the story of his investigation into an Israeli soldier’s killing of Palestinian-American journalist Shireen Abu Akleh in 2022 and the unsuccessful attempts he made to ensure the US State Department would accurately report his findings: that Abu Akleh was intentionally shot.

Gabavics previously discussed his experience investigating Abu Akleh’s killing just days after it happened in a documentary produced by Zeteo News, but he wasn’t named in the film.

On Monday, he came forward publicly for the first time in an interview with the New York Times to discuss the case he said has “bothered [him] the most” of any he investigated during his 30-year military career.
