Natalee Holloway was declared legally dead Thursday by a judge in her home state of Alabama. She mysteriously vanished in Aruba more than six years ago.
Probate judge Alan King made the ruling at the request of Holloway's father.
While her body was never found, Dave Holloway met a legal presumption of death for his daughter, according to King, who had set Thursday as the deadline for anyone to come forward and prove she didn't die on the Caribbean island.
With no evidence to the contrary, Natalee Holloway is legally deceased.
The ruling comes just one day after longtime suspect Joran van der Sloot pleaded guilty to the murder of another woman, Stephany Flores, in Peru.
Van der Sloot's lawyer said the 24-year-old killed Flores in 2010 due to "extreme psychological trauma" he experienced in the Holloway investigation.
