The Tempe Police Department said Sunday that 23-year-old Elizabeth Johnson is being held at the Maricopa County jail on the three felony charges after being extradited from Florida, where she was taken into custody Dec. 30 after failing to show up for a custodial hearing in Phoenix.
Police say she's being held on a cash only $1.1 million bond.
Authorities are trying to determine what happened to Johnson's 8-month-old son, Gabriel, who was last seen with her in San Antonio last month.
Authorities are calling a Scottsdale couple "persons of interest" in the case.
The couple has said they befriended Johnson at an airport and that she wanted to give her son up for adoption.
