In another incident, police said a 27-year-old African American man in Volusia County, Fla., taped a note with "KKK" and "Trump" written on it to his girlfriend's mailbox this week, then threw a brick through her car window and spilled gasoline on her back seat because he was mad at her over a child custody battle. The man made it look like a hate crime to deter police from investigating him, authorities said.
