PORTLAND -- The biological mother of a missing Oregon boy says her civil suit against the boy's stepmother should move forward.
Desiree Young says in a motion to be filed in court on Thursday that Terri Horman should not be allowed to delay Young's suit by two years.
"She (Young) believes the defendant (Horman) is responsible for the disappearance of her son, and is entitled--under both the United State and Oregon Constitutions--to pursue these claims in a timely manner," the motion reads.
Horman asked for the delay last month, saying a criminal investigation should conclude before Young's suit goes forward.
Young believes that Horman "seeks to bar all discovery into the circumstances of Kyron's disappearance."
Kyron Horman was 7 when he vanished from a June 2010 science fair and investigators have found no trace of him.
Police have not named Horman as a suspect or filed charges but have focused on her during the investigation.
