ORANGE -- Police in Southern California say they've arrested a woman whose 7-month-old son was tossed from the upper level of a parking structure.
The baby is in critical condition at University of California, Irvine Medical Center.
Orange police Sgt. Dan Adams says 31-year-old Sonia Hermosillo of La Habra was arrested late Monday and booked for investigation of attempted murder. She is being held without bail.
A witness called 911 after seeing the baby falling to the ground just after 6 p.m. on Monday. The baby went over the rail, possibly from the 4th floor, of the parking structure at Children's Hospital of Orange County.
Investigators say surveillance video shows Hermosillo's tan Chevrolet Blazer sport utility vehicle with an empty child restraint seat leaving the parking structure.
La Habra police received a 911 call Monday evening from Hermosillo's husband reporting his wife and infant son were missing.
