Even as police focused attention on missing Oregon boy Kyron Horman’s stepmother, the 7-year-old child’s family maintained a united front – until now.

Within the last two days, Kyron’s father, Kaine Horman, has moved out of the house he shared with wife Terri Moulton Horman, and he brought their 18-month-old daughter Kiara with him, a source tells PEOPLE.

On Monday night, Terri Horman was served with a restraining order and divorce papers, the Oregonian reports.

Meanwhile, Kyron’s mother, Desiree Young, and her husband Tony, have joined Kaine Horman in releasing a cryptic statement saying they’re pulling back from the public eye.

“We understand that we have free access to the media but are limiting statements to the media to keep the integrity of the investigation intact,” the three stated. “Any actions taken by the investigation, or by us, are based on the best interests of Kyron and Kiara and comply with the law. Beyond this, we have no comment on the matter.”

Terri Horman’s name is not included in the statement, and a source tells PEOPLE she is no longer officially speaking for the family as she has in the past.

As recently as last Friday, Kyron’s father said he believed his wife was “committed” to finding the boy.

Terri, who has helped raise Kyron since he was a baby, was the last person known to have seen him, telling police she dropped the second-grader off at a science fair at his Portland-area school on June 4.

Since then, she has taken two polygraphs and deputies sent out a questionnaire asking if anybody had seen Terri or her truck the day the boy disappeared.

Terri Horman’s dad tells PEOPLE in the current issue she’s been interviewed repeatedly, as long as six hours at a time, and that police have inspected her truck twice. Asked if he thought authorities would arrest Terri, her father said it was “50-50.”
