As online rumors about a possible Austin serial killer continue to swirl, concerned residents launched a petition demanding that city officials add lighting and emergency call stations along Lady Bird Lake. “With more than 2.6 million visitors a year, the 10-mile hike and bike trail is Austin’s most recognized and popular recreational area,” the petition says. “However, directly next to this urban path lies Lady Bird Lake, which has now been the scene of over a dozen deaths within the last decade.”
