KANSAS CITY, Mo. (AP) — The investigation into the shooting by a homeowner of Ralph Yarl, a Black teenager who went to the wrong house to pick up his younger brothers, includes questions about whether it was racially motivated, authorities in Kansas City said. Police are quickly preparing evidence for prosecutors in Thursday’s shooting, Chief Stacey Graves said Sunday at a news conference at police headquarters. “I want everyone to know that I am listening,” Graves said, “and I understand the concern we are receiving from the community.” The Kansas City Star reported that the 16-year-old victim, identified online by family members as Yarl, was hospitalized Thursday night after he was shot while trying to pick up his younger twin brothers from a friend’s house.
