PORTLAND, Ore. -- The father of missing Portland boy Kyron Horman has filed for divorce and taken out a restraining order against his wife, a source told KGW Monday night.
A source close to the investigation told KGW Monday night that Kaine Horman had moved out of the home with his 18-month-old child.
Family members released a statement Monday saying they were in support of the investigation. The statement was signed by Kyron's father, stepfather and mother, but not Terri Moulton-Horman.
Read the statement
Kyron Horman's photo was on the cover of 'People' for the second week in a row and the story that goes with it focuses on the attention that has been placed on his step-mother Terri Moulton-Horman.
Since Kyron vanished three weeks ago, she has been singled out in a questionnaire sent to parents and staff of Skyline school. A lifelong friend described Terri Moulton-Horman's unhappiness with a second polygraph test.

Terri Moulton-Horman said she was not aware a statement was coming out. A source close to the investigation however, said her husband Kaine and their 18-month-old child had moved out.
Moulton's father, Larry Moulton, 72, told 'People' matter-of-factly that "the finger points at stepmom, she's trying to be cooperative."
He too said she has had two polygraphs, that police have taken her truck twice and questioned her several times, for up to six hours, several times. He also described his daughter as "really good with kids" and pointed to a Halloween outing to pumpkin patches with the family in costume.
Parents grant TV interview
The People magazine cover story comes right after Kyron's mother and father sat down with KGW and answered some of the most commonly-asked questions, including why investigators had focused on Sauvie Island. However, Kyron's parents would not answer questions about Terri Moulton being given lie detetor tests, and they said she would not be speaking to the media.

Questionnaire singles out Terri Moulton
Police scoured scores of questionnaires turned in by parents of Skyline Elementary School children, staff members and even delivery drivers for new clues last week as they tried to untangle the mystery of Kyron's disappearance.
The questionaires contained several questions that were intended to help trigger people's memories about the day that the seven-year-old disappeared.

Among the questions were: "Did your child see Kyron's step-mom, Terri on 6/4/10, at or near the school?" and "Did your child see a white Ford F250 pickup truck on 6/4/10 at or near the school?" Terri Horman, Kyron's step-mother, was driving the white truck on the day he disappeared. The questionnaire also showed photos of Terri and the truck.
Capt. Jason Gates said during a press conference that the photos and questions were an effort to "jog people's memory" in the case, since Terri was the last person who spent time with Kyron.
Gates added that the family was in full support of the decision to circulate the new questionnaire Friday. He read a family statement that said, “Any parent would understand the grief that this causes our family… please know that we fully support the release of this flier and we want Kyron home and we hope that this will do that."

KGW has learned that police over the weekend also asked Terri to take a second lie detector tests as part of the investigation.
A close friend of Terri's told KGW she is a wonderful mother who's known Kyron since he was three days old. She said the extra scrutiny has taken an emotional toll on her.

Gates refused to comment about any possible suspects or "persons of interest" in the case.

The other questions on the form were more generic in nature, including “Did your child see Kyron on 6/4/10?” and “Where did your child see Kyron?”
Case gets national attention
The biological mother of missing seven-year-old Kyron Horman reached out with an emotional letter to her son, hoping and praying that he would return home and read it soon. Desiree Young shared the letter with NBC's 'Today Show' as part of their ongoing coverage of the missing boy case.
