Joran van der Sloot's lawyer says his client will plead guilty to killing a young Peruvian woman he met gambling but argue temporary insanity in a bid for a shorter sentence.
The attorney for Van der Sloot, who remains the key suspect in the 2005 disappearance of U.S. teenager Natalee Holloway on the Caribbean island of Aruba, says his client will use the "violent emotion" defense in the Stephany Flores case.
Attorney Maximo Altez says Van der Sloot became enraged and killed Flores last May because she learned of his relation to Holloway by looking in his laptop.
If the plea is accepted, Van der Sloot would be sentenced to 3 to 5 years. He is charged with first-degree murder, which carries a 15- to 35-year sentence on conviction.
