"She was recommended to me by the National Center for Missing and Exploited Children," Shipman said. "I've already spoken to her and she'll take the case; I just need the funds to hire her."
Shipman said the investigator will work closely with the FBI on the case, but, as they can't travel to England to search on the ground, it's necessary to hire a private investigator.
"The FBI people don't have the capacity to work as closely with the English police," she said. "The private detective is the best way to speed up the process."
Shipman said the investigator comes highly recommended by the NCMEC.
"They said that this agency has expertise in finding missing kids," she said. "Of 2,000, 1,900 were recovered."
Shipman said that as soon as she has the money from the benefit this weekend, the investigator will start her search.
"As soon as I get her the money, she'll start making it public -- putting up posters and putting it on TV and stuff," she said. "Then we just hope for information."
Hope is something Shipman is still holding onto, despite the fact that her daughter has been in the hands of a man with a confirmed history of mental illness for nearly three months. Hiring the investigator is a proactive step that has made her more optimistic that her daughter will come home.
"Right now, I'm surviving day by day," she said. "I just hope that lots of people will come this weekend and help bring Deonna home."
