RICHMOND, Va. (AP) — The sister of a Black man killed by Richmond police in 2018 has announced her candidacy for next year’s Virginia gubernatorial race.

Princess Blanding is the sister of Marcus-David Peters. He was a 24-year-old high school biology teacher who was fatally shot by a Richmond police officer while experiencing a mental health crisis.

Blanding said Tuesday that she is running under the banner of the newly formed Liberation Party. Blanding said her platform is “to build a diverse, inclusive, and liberated Virginia for all.” Since her brother’s death, Blanding has become an activist on police reform and social justice issues.
