The baby, still strapped to her car seat, was found Monday afternoon by some people passing by. Police said the baby was not inside a vehicle and there was no one nearby claiming to be responsible for her.
According to investigators, her father, 33-year-old Jason Buchea of Costa Mesa, had called police to report his daughter missing.
Buchea and the baby's mother, who is a student at the college, were questioned. After the interview, Buchea was arrested for child endangerment. The mother was not arrested.
The baby was taken into protective custody by the Orange County Child Protective Services.
