Police in Tampa, Florida, have arrested a man they believe murdered India Clarke, whose death put her on a growing list of transgender woman killed violently in the U.S. this year. DNA evidence linked 18-year-old Keith Lamayne Gaillard to Clarke's death, according to a Hillsborough County Sheriff's Office press release. Investigators found Gaillard's DNA under Clarke's fingernails, as well as on a condom containing fluid in her car.
