Holloway disappeared in 2005 on a post-high school trip to Aruba. Her disappearance has remained a mystery, as no one has been charged.
Ludwick was a friend of Joran van der Sloot, the prime suspect in the Holloway case. Holloway was last seen at a bar in Aruba with van der Sloot.
Van der Sloot is currently serving a 28-year prison sentence in Peru for killing student Stephany Flores on the fifth anniversary of Holloway’s disappearance in 2010.
North Port police said they've informed authorities involved in the Holloway case of Ludwick's death.
