Police said Tuesday they are making progress in the case involving a missing 8-month-old boy and are continuing to investigate conflicting statements made by a couple named as persons of interest.
The results of a polygraph test taken Friday by Jack and Tammi Smith of Scottsdale, who wanted to adopt Gabriel Johnson, came back as "inconclusive," according to Tempe police Sgt. Steve Carbajal.
The Smiths were named persons of interest by police last week because investigators believe they are withholding information that could possibly lead them to the whereabouts of the child. However, police would not release specifics of any progress that was made in the case as about 35 tips come in a day, police said.
The baby's mother, Elizabeth Johnson, was extradited late Saturday from Florida to a Maricopa County jail, where she is being held on a $1.1 million cash bond. Johnson remained uncooperative with authorities about the child's whereabouts and also is facing charges of kidnapping and child abuse, police said.
The Tempe woman claimed she killed Gabriel and left him in a dumpster, but police believe the child is still alive. The child's disappearance has sparked a nationwide search.
Gabriel was last seen with his 23-year-old mother Dec. 26 at a hotel in San Antonio. She lost custody of her son to the boy's father, Logan Scott McQueary, two days later when she failed to show up at a custody hearing.
Johnson was arrested Dec. 30 at a youth hostel in Miami Beach, Fla., and held while awaiting extradition. She told McQueary that she killed the baby and left him in a trash bin. But police have said they believe Gabriel is alive, and they are investigating whether she gave him away.
Results from a polygraph test can be "deceptive," "truthful" or "inconclusive," Carbajal said. In this case, the results came back inconclusive.
"It doesn't really clear things up," Carbajal said of the Smiths' polygraph results. "We're still investigating and asking for leads and looking at everything."
Kim Hale, commander of investigations for Tempe police, said Monday that Johnson was "very quiet and standoffish" when aboard the plane back to Arizona from Florida.
"She was not forthcoming with any information - and she's been that way since she was arrested," Hale said. "At this point, the baby could be anywhere. When asked if she wanted to be helpful in locating where her baby was, she had nothing to say."
Authorities appealed to whomever may have Gabriel, saying the child can be turned over to a fire station or hospital if that person is afraid to come forward.
If anyone has any information about the boy's whereabouts, they can call the National Center for Missing and Exploited Children at (800) 843-5678.
