AMSTERDAM (AP) — A Dutch newspaper says that Joran van der Sloot, who is serving a 28-year-sentence for murdering a young Peruvian woman, has impregnated a woman while imprisoned in Lima.

De Telegraaf newspaper on Monday cited Van der Sloot's lawyer Maximo Altes as saying the pregnancy is past its third month, and Van der Sloot himself as confirming the news in a telephone call. The woman, identified by the paper only as "Leidi," was said to have become pregnant during an unsupervised visit with Van der Sloot.

Van der Sloot was convicted for robbing and killing Stephany Flores in 2010. He is also wanted in the U.S. in connection with the disappearance of teenager Natalee Holloway, of Alabama, in Aruba in 2005. He could resist extradition if he obtains Peruvian nationality.
