It has been an agonizing week for the family and friends of Natalee Holloway.
Yellow ribbons now dot Mountain Brook, Ala., near Birmingham, where she lives.
In an interview with CNN on Sunday, Natalee's aunt, Marcia Twitty, said there is no way Natalee would have left of her own free will.
"No. There is nothing about Natalee where on her own free will, where she's gonna say, I'm not going... uh uh," said Twitty. "No. Her own free will? Natalee would not do this."
Daily prayer services are being held for the 18-year-old in Mountain Brook. And a prayer vigil will be held Monday at 6:30 p.m. in Meridian at Poplar Springs Drive Baptist Church, where her father, Dave Holloway, is a member.
Sunday night, at least 70 people showed up for a prayer vigil at a lighthouse on Aruba's gusty northwest point, singing a hymn and listening to a brief sermon by the Reverend Larry Waymire, an American who has lived in Aruba for six years.
Waymire, originally of Lexington, Tenn., says it's a trying time, not only for Aruba but for the world as a whole. Waymire says Holloway's disappearance has "touched the lives of millions of people around the world."
