On July 22, 18-year-old Nia Wilson was murdered in a stabbing at a transit station in Oakland, California.
The teen had just stepped off a Bay Area Rapid Transit (BART) train with her two sisters, one of whom was also targeted in the incident but survived. The "prison-style attack" on Wilson, who was black, may have been a racially motivated hate crime, according to investigators.
"It's nothing imaginable, seeing your child on the BART platform with a yellow tarp over her body," said Wilson's father, Ansar Muhammad. "That is an image I'll never forget for the rest of my life."
