Standing beside a sign that bears Mr. Peters’ name and photo, Ms. Blanding tells reporters she misses her brother and appreciates the outpouring of love from people attending the event. She said she would never tire of fighting on his behalf and for others suffering from mental illness. A high school biology teacher, Mr. Peters was 24 when he was fatally shot by a Richmond Police officer in May 2018 while experiencing what has been described as a mental crisis.
