TEMPE, Ariz. -- Logan McQueary laments the day he gave Gabriel back to Elizabeth Johnson.

"I wish I didn't have to bring him back. None of this would have happened," said McQueary at his first public press conference in two weeks.

McQueary expected Johnson would live up to their joint custody agreement; however, police say she kidnapped her boy and ran to Texas. Once there, police say she either killed Gabriel or simply gave him to strangers.

"I think about it every single day whether he's dead or alive. I want to believe that he is alive, I just want her to tell the truth," said McQueary.

McQueary was especially disheartened by hotel room pictures of Gabriel released by Tempe investigators.

They were taken by Elizabeth while on the run in San Antonio. Gabriel can be seen clutching a bottle of baby Tylenol and his eyes appear unnaturally heavy.

"I've never seen him like that. When I saw that picture, I started crying. I've never seen him like that at all. He wasn't just tired, he's never looked like that before," said a tearful McQueary.

On Monday, Elizabeth Johnson told her grandfather, Bob Johnson, that if she's already facing jail time for kidnapping, she may never tell the truth.

Person of interest Tammi Smith, who planned to adopt Gabriel, has already lied about falsifying Johnson's paternity paperwork. According to her criminal record in Louisiana, Smith spent a night in jail for forging her second husband's signature on his checks.

McQueary thinks Tammi Smith and her current husband Jack know more than they are saying, but came forward today to get their faces out of the news.

"This is about Gabriel and I want to find my son. Everybody's been concentrating on the Smiths and I don't think it's about them. It's about finding my son," said McQueary.
