Kyron Horman Update: Parents Plead For Cooperation From Stepmom's Friend

PORTLAND, Ore. (CBS/KOIN/AP) Desiree Young and Kaine Horman, the biological parents of missing 7-year-old Kyron Horman, are pleading with a reported friend of the boy's stepmother to help investigators. In an e-mail sent to media outlets Thursday, the concerned parents, along with Desiree's husband Tony Young, stated that stepmother Terri Horman has been receiving advice that is "not in the best interests of our son" from friend DeDe Spicher (spicer). 

Kyron Horman vanished June 4, and his  stepmother is believed to be the last person to see him, when the boy was walking towards his second-grade classroom after a school science fair. Police began searching for Kyron after the stepmother reported him missing when he did not arrive home on his afternoon school bus.

The family's pointed e-mail states, "Additional information provided shows that she (DeDe Spicher) is refusing to cooperate with law enforcement, she is also going as far as to suggest to others that may have information regarding Kyron's disappearance, not to cooperate as well."

The letter stressed the importance of Spicher's cooperation in the ongoing case to find their son. According to the Associated Press, Spicher did not immediately respond to an e-mail asking for her comment.

In the e-mail, the family indicated that, "...If we find out that through the investigation that she caused a delay in us finding our son due to her lack of cooperation, we will pursue civil remedies in this matter."

Multnomah County Sheriff's spokeswoman Mary Lindstrand declined to comment on the family's email.

Terri Horman has not been named a person of interest or a suspect in her stepson's disappearance.
