Joran van der Sloot was formally charged Thursday with murder in the death
of a Peruvian woman who had allegedly discovered his link to the disappearance of Natalee Holloway.
The Dutchman faces a 30-year prison sentence and a restitution payment of $73,000 to the family of Stephany Flores, 21, who was found bludgeoned to death in van der Sloot's hotel room in Lima in May 2010, CNN reports.
Van der Sloot has offered to plead guilty
, claiming temporary insanity, but is seeking a much shorter prison term, his lawyer has said.
He allegedly killed Ramirez after becoming enraged when he realized she had looked at his laptop and learned of his connection to 18-year-old Holloway, who disappeared
from the island of Aruba in 2005.
