Austin police have identified the mother of a baby found in a dumpster on Oct. 25 as 27-year-old Althea Johnson.

Althea Johnson, 27.

Johnson was arrested on Tuesday morning on a charge of abandoning a child, according to Austin police.

Johnson’s newborn girl was found in a dumpster at an apartment complex in the 9600 block of Middle Fiskville Road around 7 a.m. as temperatures dropped to 51 degrees in the area.

Medics found the baby in serious, if not critical condition and rushed her to the Dell Children’s Medical Center for treatment. A Child Protective Services spokeswoman said the infant was released from the hospital and returned to her family, though additional specifics were not available.

Austin police officer Destiny Winston, a department spokeswoman, said without the 911 call, first responders may not have arrived in time to save the child.

The day after the child was found, police said they had identified the mother, but did not publicly name her or file charges until Tuesday.

Abandoning a child is a second-degree felony punishable by two to 20 years in prison and a fine of up to $10,000.
