Joran Van der Sloot is serving a 28-year murder sentence for one young woman's death and is the main suspect in another, but that won't keep him from becoming a married man this week, reports Reuters. Tomorrow, the 26-year-old will marry Leidy Figueroa, the 24-year-old Peruvian girlfriend he impregnated on a conjugal visit. She is due to give birth in September. Van der Sloot was convicted of killing a 21-year-old Peruvian woman in 2010, and he is suspected in the 2005 death of American Natalee Holloway in Aruba. Holloway's body has never been found, and Peru promises to extradite Van der Sloot for questioning after he has served his sentence.
