(CBS) BIRMINGHAM, Ala. - Natalee Holloway's mother told her attorney she found little comfort Wednesday in Joran van der Sloot's courtroom admission that he killed a Peruvian girl in 2010.
The New York Daily News reports lawyer John Q. Kelly said, "It doesn't bring her any closer to any resolution of Natalee's disappearance." He said Beth Holloway's ongoing pain continues to be "immeasurable."
Kelly's still-grieving client scoffed at Van der Sloot's so-called "sincere confession" to the murder of Stephany Flores.
The 24-year-old Dutchman claimed he suffered from post-traumatic stress disorder due to accusations that he killed Natalee Holloway during the teen's 2005 trip to Aruba, Kelly said. This was particularly offensive to Holloway's mother, her attorney stated.
"It's just outrageous and unfathomable that he's using his torment of the Holloway family, his refusal to cooperate and his extortion and fraudulent behavior as a reason why he deserves sympathy," Kelly told the Daily News.
Beth Holloway is happy Van der Sloot won't walk free in Peru but she still hopes the Department of Justice will extradite him on pending charges that he extorted $25,000 from her in 2010 with a false promise to direct investigators to Natalee's remains, Kelly added.
"Obviously, she'd like to see him as miserable and suffering as much as possible in a jail somewhere for the immeasurable pain and misery he's inflicted on her and her family," Kelly said.
Van der Sloot fled to Peru shortly after the alleged extortion and then killed Flores, 21, after meeting her in a casino in Lima, authorities said.
He maintains publicly that he did not murder Holloway, then 18, and who was last seen leaving an Aruba nightclub with him.
Peruvian authorities said the now-convicted murderer killed Flores in a fit of rage after she perused information about Holloway that was stored on his laptop.
