PHOENIX -- The newest private investigator to handle the baby Gabriel case tells CBS 5 News several witnesses told him the baby's mom had a male companion starting the first night she was in San Antonio.

Ken Gamble, of Gamble Investigations Inc., was in the audience during a hearing Wednesday morning in Phoenix, when a judge denied a request from the mother of missing baby Gabriel Johnson for a new lawyer.

Johnson, 23, asked for new representation because she said her current attorneys were ignoring her request to ask the judge to reconsider letting her out of jail, according to Judge Timothy Ryan.

Johnson also told the judge she felt her lawyers were pressuring her, but Ryan said it was for her own good.

"The reality is they have a case involving baby Gabriel, and the police want to know where baby Gabriel is located," Ryan told her. "So when your attorneys come to you for information from the police … the reason they're doing that is not to pressure you. It's their ethical responsibility to talk to you about those things."

Gamble wanted to meet with Johnson, but she has yet to agree. But even without that meeting, Gamble told CBS 5 News that there is no evidence that Johnson killed Gabriel. He said everything points to her giving him up in an underground and illegal adoption. Gamble remains confident Gabriel is still in the United States.

Johnson is currently charged with kidnapping and custodial interference in connection with the disappearance of her son Gabriel, who was last seen with her in San Antonio, Texas, on Dec. 26.

Johnson was arrested several days later in Florida and extradited to Maricopa County.

She told police that she gave Gabriel to a couple in San Antonio; however, she told Gabriel's father that she had killed the baby and dumped him in the trash.
