Although Gabriel appears to be healthy and active, lying on a bed with toys and a pacifier, investigators fear that Gabriel is holding a medicine dropper in two of the photos.
"Elizabeth told me to give him a bottle in about an hour and then her exact words were to 'Give him more medicine if he started crying to shut him up,'" Urias said.
"Gabriel wasn't acting like a normal baby," she said. "He was acting scared, he didn't want to play. He acted like he was sad."
The photographs were found on Johnson's camera following her arrest Dec. 29 in Miami.
In another claim, Urias said she found a large knife next to the bed in the motel room.
"It looked like a butcher type of knife and, you know, I thought that was weird because why would she have it next to her bed? It's something that would belong in the kitchen," Urias said.
The photographs were date-stamped Dec. 26, the last day anyone saw Gabriel.
Anyone with information about Gabriel Johnson is asked to call the Tempe Police Department at (480) 350-8311.
