Beth Holloway spoke out Tuesday, a day after Joran van der Sloot allegedly confessed to killing 21-year-old Stephany Flores in Peru. Van der sloot was suspected in the 2005 disappearance of Holloway's teen daughter Natalee Holloway in Aruba.

Holloway gave a press conference in Washington, D.C. at the opening of the Natalee Holloway Resource Center at the National Museum of Crime and Punishment, and got emotional as she spoke of the Flores family, saying, "It's been a stressful time for me, and I know it's been a very trying time for you. Again, thank you for your continued support, and please, again, let's all remind ourselves and keep the Flores family in our hearts and in our prayers."

"When Natalee went missing in May of 2005, my family desperately needed contact information, law enforcement information, government resources, missing person poster development, [resources on] how to organize foot soldiers and command centers, media engagement and management -- a plan of action. I partnered with the Museum of Crime and Punishment ... to form the Natalee Holloway Resource Center [whose] main focus is education and crime prevention. In the event a loved one goes missing, the Natalee Holloway Resource Center can be the family's first stop," Holloway said in explaining the purpose of the center.
