BEAVERTON -- Desiree Young, the birth mother of missing 7-year-old Kyron Horman, called reporters together to read an open letter to the boy's stepmother, Terri Horman, warning her she will "go to jail" if she doesn't cooperate with investigators.
Young and the boy's birth father, Kaine Horman, have previously said they believe Terri Horman is involved in the boy's disappearance. Investigators have not called Terri Horman a suspect, but one of her attorneys admitted in court papers filed this week she is a "de facto suspect" after he disappeared June 4 from Skyline Elementary School.
After the statement, Kaine Horman and Desiree Young met with the press in a series of one-on-one interviews Friday to discuss the case.
The two said they planned to move the wall of hope from Skyline Elementary before school starts. They also planned to mark Kyron's September 9 birthday with rememberances.
Police have received more than 3,700 tips in the case, and the focus of their investigation has been on Kyron's step-mom Terri Horman, but she has not been named a suspect or person of interest in the case.
"It's difficult," Desiree said. "I have a challenge with the people putting their needs before his."
No one has been named as a suspect or person of interest in the case.
Teri Moulton Horman appreared at a court hearing on her and Kaine's divorce proceedings Wednesday. A judge determined she must reveal her attorney funding sources in a hearing set for the divorce on October 7.
Kaine said he wanted to speak out to "have something positive out there" in keeping the focus on Kyron.
The two declined to comment on any details from law enforcement.
"I feel like we're back in the first days of the investigation," Kaine said.
