"We implore Terri Horman to fully cooperate with the investigators to bring Kyron home," the boy's mother, Desiree Young said, reading at a media briefing from a joint statement with Kyron's father, Kaine Horman.

Terri Moulton Horman is the last person known to have seen the second-grader before he vanished on June 4. Investigators have not named her as a suspect or a person of interest in Kyron's disappearance, but she's been the focus of the probe.

A call to her high-profile defense lawyer, Stephen Houze, was not immediately returned Thursday. She retained him earlier this week.

The statement from Kyron's mother and father, obtained by CBS affiliate KOIN, also said they're hopeful that  Kyron is still alive.

"Keep his face out there, keep looking for him," Young said. "We're optimistic Kyron will be found, and we can't comment beyond that."

She added that Kyron is allergic to bees and has a red birthmark on his forehead.

Anyone with information on the whereabouts of Kyron Horman is asked to call the Multnomah County Sheriff's tip line at 503-261-2847.
