A Connecticut state trooper who fired seven rounds into a stolen car and killed a man in 2020 after a 30-mile high-speed chase has been charged with manslaughter after a more than two-year investigation found the shooting not to be justified, officials said Wednesday.

Trooper Brian North turned himself in Tuesday evening to the state inspector general at the state police barracks in Bethany, state police told the Associated Press.

North fatally shot 19-year-old Mubarak Soulemane in January 2020 as Soulemane sat in the driver's seat of a stolen car in West Haven, where the chase ended and police boxed in the car. North told officials he feared Soulemane was going to attack other officers with a knife.

In a report released Wednesday morning, Inspector General Robert Devlin's office said the shooting was not justified.
