No Bond for Georgia Couple After Boy Missing for 4 Years

— -- A judge in Georgia today denied bond to a couple accused of hiding the man's son in a secret compartment in their home where he was found by police four years after being reported missing.

Gregory Jean and his girlfriend Samantha Davis are charged with false imprisonment, cruelty to children and obstruction of justice, according to ABC News affiliate WSB-TV.

The 13-year-old boy had an emotional reunion with his mother after police found him Saturday behind a hidden wall inside his father's garage. He was reported missing by his mother after a visit with his father, according to police.

"I just couldn't believe it," said Daniel Clay with the Clayton County Police Department. "We found him."

Clayton County police also arrested three juveniles inside the home.

The boy was found after sending a text message from a secret smartphone app to his mother, police said.

"We came here to the home and were able to get inside the home, talk to the people inside," Clayton County Police Sgt. Joanna Southerland told ABC News.

But police left the home empty handed. The boy then sent a second message saying exactly where he was hidden.

Police found the boy tucked away behind a fake wall - concealed behind a linen closet - within an insulation area above the garage.

"We opened the compartment where he was," Southerland said "I saw him and asked him to come forward and he was horrified. He was frozen with fear."

The boy was reunited with his mother amid hugs and tears.

"He just kept saying, 'Thank you, thank you, thank you,'" said Clay.

Jean, 37, and Davis, 42, were scheduled to make their next court appearance on Dec. 9.
