PORTLAND -- The stepmother of a missing Portland boy is trying to keep her biological son off of the witness stand in a civil lawsuit filed by Kyron Horman's mother Desiree Young.
Kyron was last seen on June 4, 2010 at SkylineElementary School.
Terri Horman is being sued for $10 million by Young, Kyron's biological mom, who claims Horman is responsible for the boy's disappearance.
In court papers, Terri Horman's lawyers suggest they will file a motion to prevent her own teenaged son from testifying in the civil suit. They also want the case postponed. A hearing was set on the issue for August 15.
Desiree Young's attorney said he would use the civil suit to peel back the mystery surrounding Kyron's disappearance by issuing subpoenas for witnesses to testify about what they know.
But Terri Horman's legal team doesn't want her son talking. The 17-year-old is believed to be living with his mother and her parents in Roseburg.
