A woman who crashed her car through a security gate at Phoenix's airport three years ago and drove onto a runway with her infant son in the vehicle has reached a plea deal in which she won't serve any time in jail.

The no-contest plea on a child abuse charge calls for 24-year-old Koko Nicole Anderson to be placed on probation, attend parenting classes, undergo mental health treatment and monitoring. She also must pay unspecified restitution for the 2012 security breach at Sky Harbor International Airport.

Investigators initially suspected Anderson was under the influence of an unknown drug, but ultimately didn't find any traces of illegal substances in her system.

Anderson told KPHO-TV in late 2013 that she has bi-polar disorder and wasn't taking medication at the time because she was breast-feeding.
