“I put him in his crib, and now he’s not there. And there was a knife laying next to my bed.”
This excerpt from a 911 call is Brianna Marshall, an 18-year-old mother who realized her newborn baby had gone missing.
Marshall called police distraught to report newborn Kayden Powell had disappeared.
Also gone, Kristen Smith, her half-sister who's now charged with the abduction.
The FBI says Smith confessed to taking the newborn and leaving him in a plastic storage bin.
Investigators say they found online conversations where she claimed to be pregnant.
