FORT WORTH, Texas - The Supreme Court will not hear an appeal by former Fort Worth police officer Aaron Dean, who was convicted of manslaughter in the shooting of Atatiana Jefferson.
Dean shot and killed Jefferson through the window of her mother's home in 2019 after a neighbor called a non-emergency line.
Aaron Dean
A Tarrant County jury found Dean guilty of manslaughter in 2022. The former police officer was sentenced to nearly 12 years in prison.
Dean was originally charged with murder and his legal team has argued that prosecutors should not have been allowed to consider the lesser charge of manslaughter.
An appeals court previously upheld Dean's manslaughter conviction.

It later came out that Jefferson and her nephew had opened the door because they had burned hamburgers.
Jefferson's nephew, Zion Carr, testified that she had a gun in her hand because she believed Dean was an intruder.
