SPANAWAY, Wash. - Diana Smith has no doubt her daughter was murdered. Accepting the death is another matter.
"Please let it be over," Smith said.
Smith's daughter, Misty Copsey, was last seen on September 17, 1992. Twenty years later, Smith is asking the public for help in solving the case.
"I know more than one person knows what happened to her," said Smith.
Early in the evening that late summer night of 1992, Copsey missed the last bus home from downtown Puyallup to Spanaway.
Copsey called her mother from a pay phone and said she needed a ride home. Smith, who was working that night, told her daughter to call her grandmother for a ride.
That was the last time Smith spoke to her daughter.
"When I got home, got in the house, she wasn't there and my heart just dropped," said Smith, "I knew something happened to her."
Police interviewed and even polygraphed a number of Copsey's friends.
But no one looked suspicious to them.
The next year volunteer searchers found clothes that Smith said belonged to Copsey.
No one has ever been named as a suspect in the case.
Smith hopes over the past 20 years someone's conscience might get the best of them.
Smith wants someone to come forward.
"She needs to be put to rest. Where she can rest and I can come and see her," said Smith
