DAYTONA BEACH, Fla. -

The lawyer defending a mother accused of driving her van full of kids into the ocean filed a motion that suggests she was suffering from hypoglycemia at the time of the incident.

The motion filed by Ebony Wilkerson's public defender claims she has low blood sugar and that may have contributed to her state of mind moments before the car went into the Atlantic Ocean.

Wilkerson faces three counts of attempted second-degree murder and child abuse following the March incident.

According to Volusia County sheriff's deputies, one of the children said that Wilkerson, who was 28 weeks pregnant at the time of the incident, locked the doors of the minivan on March 4, rolled up the windows and drove into the ocean, saying she was doing it to "keep all of us safe."

Her children -- ages 3, 9 and 10 -- were not seriously injured in the incident and were rescued by beach officials and onlookers. She delivered her other baby in May.
