Where's Rachel - 10 Yrs. Later

On Jan. 31, 1996, Rachel Mellon stayed home from school because of a sore throat. Her step dad last saw her sleeping before he went outside to take the dog for a walk around noon. Nobody noticed that Rachel had vanished until around five in the afternoon when her mother arrived home. Rachel's parents were very concerned because Rachel had left behind her purse, and her winter clothing. Where was Rachel? Had she ran away?

In 2000, a grand jury reopened Rachel's case and asked for semen, hair and blood samples from Rachel's step dad, Vince. No further actions were taken after the grand jury reopened Rachel's case. They feel that Rachel Mellon simply ran away on that fateful day, but her family do not believe that.
Six years later, Rachel was now missing for a full ten years. Rachel's biological dad had a memorial for Rachel on Jan. 31, 2006 in Bolingbrook, Illinois. There have been few answers as to what happened to Rachel and it appears that 10 years later the authorities are no closer to solving this mystery than the day it happened. Many people believe that Rachel's step dad was the one who held the clues for Rachel's whereabouts. He had several domestic violence problems and failed lie detector tests regarding Rachel.
Was vital information lost in the initial investigation? Can it ever be retrieved to find out what really happened to Rachel? Her case is one that is very strange to me. Maybe someday soon, answers can be found.
