Investigators trying to determine what happened to 18-year-old Natalee Holloway have focused their search efforts on a pond near where the Alabama teen was last seen before she disappeared nearly two months ago.
Beth Holloway Twitty said she's encouraged that authorities are moving forward and hopes they will find some long-awaited answers about her missing daughter.
The activity came a day after Holloway's stepfather, George Twitty, said two new witnesses had come forward with information about the night she disappeared. He said the witnesses place Joran van der Sloot and two Surinamese brothers near the hotel beach where van der Sloot says he left Holloway.
A police spokesman says the draining of the lake should be completed today. Investigators also await the results of DNA analysis from labs in the Netherlands and the United States.
