Charged with the murder of Stephany Flores, Joran van der Sloot is now inmate 326390, according to his mug shot. The mug shot was taken June 11, 2010. The Dutch national is seen holding his inmate number in a picture taken just before he was transferred to the maximum security Miguel Castro Castro Prison. For his own protection, he will have his own cell in a small block near the prison director’s office. Officials in Peru are hoping Van der Sloot, after having a little taste of life inside Castro Castro Prison, will come clean with what happened to Natalee Holloway.
