Austin social media accounts, including a once-dormant “true crime” Facebook group, lit up Tuesday after authorities pulled a body from Lady Bird Lake, reigniting unfounded speculation that a serial killer stalks the city. On Monday afternoon, the Austin Police Department held a press conference confirming the body’s recovery. It’s unclear how long the corpse, which has no identifiers, was in the water and whether it has any wounds, Public Information Officer Ariel Crumes told reporters.
