OLYMPIA, Wash. -- Most parents don't know what it's like to have a child disappear.
Unfortunately for Melissa Baum, that's not the case.
"Until it happens to you," Baum told KING 5,"you don't have a clue."
Baum's 10-year-old daughter Lindsey vanished while walking home from a friend's house in McCleary, Wash., last June.
Melissa Baum recently wrote an email to the family of the missing 7-year-old from Oregon, Kryon Horman. Baum wanted the family to know there was someone nearby who could relate to what they were going through.
That was something she needed last year.
"I felt a lot more alone before I met with other families," said Baum.
Baum has not heard back from the Horman family.
On Friday, investigators began to ask the public for more information about Kyron's stepmother. She was the last person to see Kyron.
Baum said that does not surprise her. She said in the first days after her daughter's disappearance, investigators asked her to take a polygraph test. She agreed.
"I tried to be pretty open and honest," said Baum, "Because my focus was, don't waste [their] time. Find my kid."
Next Saturday marks the one-year anniversary of Lindsey's disappearance.
Kyron Horman's family has been invited to join Lindsey's loved ones as they mark the anniversary in Olympia.
Lindsey's friends and family will be gathering in Olympia's Heritage Park from 2-8pm Saturday, June 26.
