Killawog, NY (WBNG Binghamton) More than 100 interviews, polygraph tests and lie detectors for an investigation stretching as far away as New Haven, Connecticut.
But nothing has helped the Broome County Sheriff's office solve the disappearance of 40-year-old Bethanie Dougherty of Killawog.
3 years to the date, her family isn't giving up hope of finding out what happened.
For the family of Bethanie Dougherty, April 1, 2008 is not a day for joking around. It's the day 3 years ago she was last seen at her home here on Jennings Creek Road in Killawog.
"I would love to find her alive," said Dougherty's brother, John Curtis.
Her sister, Billie-Jo Nuckles, said, "I won't believe she's gone until there's proof that she's gone." "What do you think happened? "I have no idea."
Surveillance video shows Dougherty at work on the 1st at Xtra Mart in Freeville. Her son last saw her wearing purple pajamas while doing the dishes at home around 10 or 11 o'clock that evening. When he returned home from school the next day, his mother's work clothes were still laid out on her bed -- something he found to be unusual.
That's when he called police. Investigators have searched miles of property surrounding Dougherty's home including neighboring wooded areas, several times, after a report of a woman screaming in the early morning hours of April 2nd. Although that has not been confirmed whether it woman or an animal sound that was heard.
"There was no evidence of any struggle," said Curtis. "Investigators say they feel it was about 80 yards from the house as to where the whole thing took place."
Sheriff's investigators say there hasn't even been one piece of evidence that points to any crime or anyone being involved in her disappearance. While reward money is being offered, most leads turn out to be rumors.
Dougherty's family is now hiring private investigators to help with their search for answers.
"I just want my sister to be found," said Curtis.
"Either way we need closure, cried Nuckles. " But I'm hoping for the best. I'm not giving up hope. I honestly believe she is still alive 100%"
Anyone with information on the case is asked to call the Sheriff's office at (607) 778 1196 or the private investigators at (607) 758 6199.
A fundraiser will be held at noon on May 1, 2011 at Denny's Mountain View in Preble, NY to help Doughtery's family pay for the investigators.
